Importance of Social Media in the Image Formation of Tourist Destinations from the Stakeholders’ Perspective

This research aimed to provide a more informed and systematic basis on which to develop the positioning strategy in social media due to the interactive capacity and influence that social media has in the success of tourist destinations. In particular, we investigated the role of stakeholders. We carried out an exploratory study using a mixed method which included interviews and an analysis of the activity conducted on the official social media accounts (Facebook, Twitter, and Instagram) of the Spanish regions of Andalusia, Catalonia, and Valencia. The findings provide insight into how tourist destinations promote their image through the use of social media. Social media was found to be a strategic platform for enhancing brand image and achieving tourist engagement. Additionally, the role of stakeholders in supporting and facilitating the image destination strategy is worth highlighting. This study shows that the results achieved by social media can be improved by identifying all stakeholders and defining a content generation strategy by integrating and adding value.


Introduction
Tourism is an economic activity that represents an important revenue source globally and is the third most important activity in the exportation category. According to the Spanish Instituto Nacional de Estadística (INE) [1], Spain banked 87,856 million EUR in tourist revenue, an increase of 3.3% compared with 2017.
The economic significance of tourism, along with the spread of globalization, given the constant demand for information in this sector, makes the promotion of tourist destinations fundamental. Yet, the speed of accessing information and the fast updating of technologies increasingly alter the behaviours of users and directly affect the business models of tourist destinations.
According to INE [1] data, currently, over 80% of users search for information on products and services prior to making a purchase [1]. This is the case when it comes to travel. Thus, the process of planning the trip is increasingly being more dominated by online tools and travellers' opinions.
The tourist industry is one of the sectors where the use of new communication technologies has had the greatest impact [2,3]. Therefore, global tourist destinations are competing to attract tourists. The main aspects involved in attracting travellers and enhancing the visibility of cities are having an online presence and successfully managing social media. However, it is not enough just to understand how tourist destinations use social media to promote themselves. It is necessary to know how stakeholders contribute to the promotion of tourist destinations and brand image.
According to the Annual Social Media Report [4], eight out of every 10 users consider social media to be a good setting to interact with brands. Due to the economic crisis and the rise of social media, destinations have increased their online communication investment to the detriment of traditional methods. This is the reason why this study solely focuses on the online dimension of promoting tourist destinations.
It is well known that the literature about destination image [5][6][7][8][9][10][11][12][13][14] and social media in tourism [15][16][17] is very extensive. Especially, there has been an increase in studies in recent years, as both concepts have been adopted together [18]. However, to date, there has been little research focused on the tourist destination brand image development concept from the stakeholder point of view. Many studies have been based on how destinations use social media to promote themselves and boost their image [19], the image perceived by tourists as a consequence of social media strategies carried out [20], or how tourists become co-creators of the image of a destination though social media platforms [21][22][23]. However, there are other stakeholders that have been unnoticed or simply not studied through a holistic and integrated manner. This is the reason why our work uses the triple helix model to address this issue as a central axis.
The main objective of this research work is to provide insight into how tourist destinations promote their image through the use of social media and how they communicate with stakeholders.
We also consider what type of content is shared to the public.
This study is divided into six sections. After this introduction, a review of the previous literature focused on social media used by tourism destinations is made and some research questions are asked. Secondly, an approach based on the stakeholder perspective using a mixed method is introduced in the methodology section. Specifically, qualitative content analysis and interviews are combined with quantitative data obtained using online tools. The fourth section deals with the empirical work and shows that social media can be used as strategic platforms to enhance brand image and generate value. The fifth part contains the main contribution. It should be pointed out that the role of stakeholders supports destinations in their image strategies. In addition, all content generated by users (UGC) involves tourists who help to form the image of a destination through social media. Finally, some limitations of the research and tips about the use of social media by tourism destinations are proposed.

Social Media in the Development of Destination Image
The World Tourism Organization [24] defines a tourist destination, from a merely geographical perspective, as follows: "a place where demand travel to consume the tourist product" (p. 20). Although tourist destinations have been widely explored in different studies, it is recognized that, as a multiactivity grouping, they compete based on a spatial cooperation strategy to offer integrated tourist products that are assessed and judged by potential tourists; this is significantly broader than the previous definition [25]. Others, such as Murphy, et al. [26], consider tourist destination to be products but offer an unparalleled experience to tourists. Gunn and Var [27] uses the term "experience" when attempting to understand what a tourist destination is. This is the result of a process where tourists use multiple tourist services during their visit.
Therefore, a tourist destination should not be based simply on a geographical definition [14,24] or on an agglomeration of services or products [26]. Tourist destinations contain the six As: attractions, accessibility, amenities, available packages, activities, and ancillary services [28].
From a tourism stakeholder approach, a destination is defined as an open system of multiple interdependent stakeholders, among whom different interactions occur and whose decisions and actions have different levels of influence and impact on others [29].
Destination image has acquired a special key role in diverse research fields such as anthropology, sociology, geography, and marketing due to the impact that it has on human behavior [30]. starting conversations and listening is also needed, not merely [telling the users] things because what they want is to be allowed to be involved in opinion forming" (p. 70). Based on the above, the following research questions were formulated: RQ1. What kind of content is shared by the official profiles of destinations selected in social media? RQ2. How is social media used to promote tourist destinations? RQ3. How does social media management affect the official profiles or accounts analyzed in terms of engagement?
The appearance of Web 2.0 has allowed tourists to have access to and control powerful mouth-to-mouth electronic tools and has given them the opportunity to express personal opinions to an audience of millions of possible other tourists [15,57].
DMOs can use social media as a place where they can obtain information about their needs as consumers and establish the relationship between the brand and consumers at an insignificant cost [58,59]. It can even be used to promote their brand image or create the idea that their destination is the next destination that a tourist needs to visit [7,60] In line with Ren, Pritchard and Morgan [61], tourism destination brand image development helps to improve marketing effectiveness and attract visitors [61][62][63] Social media is also recognised as a communication and public relations tool [64] and, as such, it allows effective communication of destination brands and aids in the development of a relationship with users [65]. Furthermore, many studies reinforce the idea that conversations between users and tourist accounts in social media help to create territories and allow the latter to identify with the users [66][67][68]. This shows that social media has positive effects on the relationship between a user and a brand, which leads to greater credibility and loyalty [68]. In recent studies [16,22], the impact of destination branding has been highlighted. Destination image is a factor that influences tourist destinations in a positive way [8][9][10]. As a consequence, social media should be considered as an active component in the development of destination image [69,70].
Social media is considered a useful tool for DMO even though its use is often limited or not fully exploited [18,71]. A greater and better effort may be needed to bring people to the brand community based on social media and to retain them as loyal consumers [72]. This leads us to propose the following hypotheses:

H1.
Tourist destination promotes its image on social media through its icons and main attributes.
H2. Social media supports the management of destination image, generating useful content for tourists.
The communication department takes this concept in account. The Andalusian Tourism Promotion Plan of Junta de Andalucía [73] acknowledges that "social media now plays a key role in the everyday life of a great part of the population, both in Spain and abroad. All economic sectors consider social media to be a fundamental factor to promote their business and that is no less true for tourist activity" (p. 75).

User-Generated Content
The impact of the content generated by users is growing rapidly and its role has become increasingly more fundamental for the success of a destination [12,74]. This was partly explained by De Bruyn and Lilien [75] who reinforced the idea that this type of content is under high demand and creates expectations about a tourist destination [75,76]. User-Generated Content (UGC), especially regarding tourist experiences, is transmitted through social media [6], allowing tourists, particularly younger people, to be involved in forming the image of any travel destination [16,71,77].
UGC in social media can be highly useful for understanding the needs and wants of tourists and specific suggestions for the products/services they consume [78]. Assessing individuals' motivations allows their choices, needs, and expectations to be understood, and this has been widely explored in tourism [79,80]. Blogs, social media, and videos are some of the elements that allow the users themselves to become influencers [81]. According to Standing et al. [82], travel 2.0 has been revolutionized because there is a large amount of UGC in the form of travel blogs and online travel reviews (OTR) that allows other users to experience the events that travellers share first-hand through social media platforms during their stay at a destination.
Theoretical frameworks allow us to accept that all content created by users takes part in the processes of building and promoting destination image [12,23,55,77,83,84].
According to Marine-Roig and Clavé [85], tourism data are considered to be a good source of information for national tourism organizations (NTOs) and other policymakers, destination marketing organizations (DMOs), and stakeholders, because they consist of opinions that are freely expressed by tourists who have visited the destination (p. 203).
At this point, another research question emerges: RQ4. User-generated content is the key to RQ4.1 Gaining more interactions RQ4.2 Understanding stakeholders' interests and expectations

Role of Tourism Stakeholders
Definitions of the term range from those that only understand stakeholders as actors of organizations [86,87] to other authors who include any actor [88].
One of the first authors to offer a broad stakeholder vision was Freeman [89], who stated that a stakeholder is "any group or individual who can affect, or is affected by, the achievement of a corporation's purpose" (p. vi). Furthermore, there are those who differentiate stakeholders into strategic and moral stakeholders [90]. A reviewing about classifications of other authors has been carried out (Table 1). Table 1. Types of stakeholders identified by authors. Source: Own elaboration.

Authors Stakeholders Identified
Timur and Getz [91]; Sun [92] Government bodies, tourist and hospitality firms, tourists (the key pieces to the tourism industry) and residents García, Gómez and Molina [93] Local residents of the destination, employees, investors, tourists, and travel intermediaries like airlines, travel agencies, and so on Sheehan, Ritchie and Hudson [94] Three pertinent destination stakeholders-the city or government, hotels, and the destination marketing organisations (DMOs) Bitsani and Kavoura [95] Tourism hosts a community including locals who are also tourism entrepreneurs Simpson [96] Government, private sector, national government organisations (NGOs) and communities Clarkson [97]; Dodds and Ko, [98] Multiple primary and secondary tourism stakeholders Six large groups of stakeholders common to all were identified (Table 2): the public sector, private sector (tourism companies and other local businesses), tourists (international and domestic), civil society [29,99], and opinion leaders and universities [100].  [89], the knowledge of the different agents that interact in the participatory procedures of tourist destinations is necessary for the understanding of their interests and expectations, as well as the interdependencies and interactions that occur between them.
In tourism, considering the role of stakeholders in communication management is important to achieve a positive image of the destination [49,101,102]. Thus, the following research question is proposed:

RQ5. How do stakeholders participate in the promotion of a tourist destination?
Sautter and Leisen [103] claimed that, in destination management, all stakeholders should be considered and this will lead to significant returns of tourism in the long term [104,105]. Stakeholder management of investor, tourist, and resident attractions first requires the identification of expectations and their interests [106].
As Saxton and Waters [107] noted in their recent work, the increasingly wide adoption of social media offers the opportunity to observe stakeholders' online engagement corresponding to organizational communication. Capriotti [108] stated that the use of indicators is key when analyzing and auditing the corporate image perceived by the different stakeholders as well as the quality of the interactions and the real effects of the corporate identity.
Gartner [34] made important contributions by proposing destination image as a cyclical process in which stakeholders play a key role [109]. Chon [110] suggested that it depends particularly on tourists' cognitive perception, while other authors [14] considered that both operate together to produce a composite destination image. The current trend in the tourist market is that tourists have become creators of original content for tourist destinations and, therefore, have become very powerful and influential stakeholders [14,111,112].
Marketing efforts should be tailored to the needs of each stakeholder (tourists, residents, tourism sector and government); thus, diluting the image of each of the various stakeholders is essential for the success of destination promotion [11,113].

Methods
All information was gathered using a qualitative approach through interviews combined with a quantitative approach with the data obtained through online tools and content analysis. The goal of these mixed methods was to provide useful practical recommendations for all Spanish tourist destinations on the use of social media. Mixed methods are a research design (or methodology) in which a researcher collects, analyses, and mixes (integrates or connects) quantitative and qualitative data in a single study or a multiphase program of inquiry [114].
Bryman [115] also suggested several practical reasons to consider mixed methods such as attractivity to stakeholders, improving the chance of getting funding, etc. In addition, Cai [116] highlighted the fact that the use of mixed methods could be a way to make both researchers and research distinctive in this research field.
In spite of the fact that a mixed methods approach was used, the qualitative part played the main role in this research. Its application is recommended for the studied phenomenon [9,21]. Quantitative analysis was chosen to classify and measure the main social media metric, engagement [60], while the qualitative method was used to gain depth in issues that could be lost during statistical processing [18].
This study began with a content analysis, an ideal tool for quantitative research, in order to use certain types of data to formulate reproducible interferences in other contexts [117]. Its usefulness for compiling, processing, and assessing large amounts of information [118] and its frequent use when describing the components of the media messages [119], made this the most appropriate investigation method for our work. We also took the model of de las Heras-Pedrosa et al. [120] into account, as this is a useful way to identify stakeholders in tourist destinations and to determine the research techniques to be applied in each case. The analysis process was partly based on the interactive model of Miles and Huberman [121], using the phases of data collection, data reduction, data display, and conclusions. These phases are shown in Figure 1. destinations on the use of social media.

These phases are shown in Figure 1. Social media from the official tourism websites of Andalusia, Catalonia, and Valencia were analysed. These destinations were selected as they are the main Spanish mainland tourist destinations according to data from INE [1], as shown in Figure 2. The cases selected may be representative of national tourist, as they include data taken from a large-scale study. The empirical evidence showed that there are extensive relationships and logic among the constructs [122]. Analysing this content means the public sector is taking government-determined actions further with tourism policies that represent government initiatives to develop tourism [123].

The social media selected for the analysis were the Facebook, Twitter, and Instagram accounts of the aforementioned destinations, because they are the most frequently used according to the Annual Social Media Report for Spain [4].
Destinations were specifically chosen as comparable destinations due to their similarities. Moreover, all DMOs manage their official social media accounts in Spanish. On the other hand, the Summer Vacation Value Report 2018 of TripAdvisor [124] revealed the 10 main international and national destinations for Spaniards and the three main sun and beach destinations used in this study stood out.

Content Analysis
Content analysis is one of the most frequently used techniques to research the promotion of social media tourist destinations. It is the set of procedures that is used to interpret communication products (messages, texts, or speech) that come from previously recorded communication processes that seek to prepare and process relevant data on the very conditions in which those texts have been produced [125].
The qualitative method mainly used in this work focused on observing, directly and inversely, the posts on the official profiles of the selected tourist destinations on Facebook, Twitter, and Instagram, along with the corporate blog of each one. A total of 1721 posts were quantified from the three communities over a 60-day period, from March 1 to April 31 (2018), a period of great tourist influx due to the Fallas and Holy Week-events and festivities that attract large numbers of tourists. The development of these festivities is considered to be the peak season, and it can represent what happens in destinations at other times of the year. In total, exactly 200 publications, taken randomly within the sample, were analysed. They were typed and recorded, and aspects such as general data, tourist destinations, social media, dates, and posts and their content were analysed. The content included the resources used (photos or videos) and what was transmitted, for example, information and suggestions.
The analysis of the data was based mainly on interview transcripts with the support of Atlas.ti software for qualitative analysis. This IT tool is useful for understanding the behavior and strategies of tourism destinations in social media.

The analysis of the data was based mainly on interview transcripts with the support of Atlas.ti software for qualitative analysis. This IT tool is useful for understanding the behavior and strategies of tourism destinations in social media. The analysis of interviews was based on the grounded theory approach [126][127][128]. First, all publications were quantified, and the frequency and types of content shared were the focuses. Finally, the level of engagement was stored and coded. Codification was conducted using the following procedure: these topics were linked with tags (word or sentences) that described the essence of the specific question. This meant that the most relevant topics from previous literature were used to support this proposal. The grounded theory approach, together with the proposed data structure, showed the dynamic relationships between concepts, themes, and dimensions. In the conclusion and discussion sections, the resulting model is compared with the existing empirical framework to highlight the contribution of this research work to the phenomenon of social media management in order to promote destinations.
Furthermore, the aim of this study was to delve further into the most promoted areas in social media and, therefore, six specific categories to be observed in the posts or tweets were defined ( Figure 3): nature, tangible heritage, urban landscape, intangible heritage, leisure, sun and beach, businesses, sports, technology, service, tourism agenda, and non-tourist information. Additionally, words such as happiness, thrilling, daring, energetic, imaginative, and charming were used to analyze the alleged emotions transmitted in each of the posts.

The categories and datasheet used for the content analysis were based on the proposal by Paniagua et al [129]. They were both applied specifically when identifying the theme of each social media post and the types of tourism promoted. In addition, the specific codes selected to determine the above categories were deduced from this study. To ensure inter-coder reliability in this analysis, in accordance with Olson et al [130], two researchers independently coded the content of the official SM accounts studied. After the whole process, a selected number of content units were compared to test the reliability.

Interviewing Experts in Promoting Online Destinations
Interviewing experts is one of the most common qualitative techniques used. In this case, we opted to use interviews to allow in-depth contact to be collected from the architects of the implementation of social media strategies (Table 3). All interviews were carried out by telephone.

Questions Objectives
The first questions were on the personal details of the person being interviewed: name and surname(s), professional profile, and institution to which they belong.
These initial questions identified the experts.
Block 1: How important do you believe it is to implement a social media strategy for tourist destinations?
The aim of this question was to get an overall picture of how the interviewees perceived the management of the social media communication.
Block 2: Score the social media strategy established for each of the selected destinations from 1 to 10.
This question sought to establish the experts' and professionals' Assessment of social media management Block 3: What are the reasons for using social media to a great extent when promoting a destination (most effective content for each type of social media, tone etc.)?
The aim of this section was to analyse the interviewees' perceptions of how a tourist destination should use social media.
Block 4: How would you identify that stakeholders are taken into account when plotting destination strategies?
This aim of this question was to identify the way in which stakeholders are considered when promoting a tourist destination. Interviews were based on the triple helix model [131,132], a collaborative model between the private and public sectors and the university. This model was used to analyse new aspects of knowledge based on collaborative relationships between the three entities.
In this case, the triple helix method was fundamental when choosing whom to interview ( Figure 4) to ensure that the interviewees represented all stakeholders. In total, eight interviews from experts belonging to the public sector, the private sector, and university were conducted.

Analysis Based on Data from Online Tools
The quantitative part of the analysis was based on different tools that can provide data to be interpreted in order to take stock and put forward proposals. Those tools, or rather the data in social media profiles obtained with them, were used to establish the activity of the users with those profiles and that of their administrators.
It would not be the first time that online tools have been used to analyse the social media activity of tourist destinations, as they have been used to measure data quantitatively and assess the effectiveness of social media engagement [133].
On this occasion, Keyhole was used to analyse Instagram and Fanpage Karma to study the interactivity and impact of the content shared in Facebook. Finally, Twitonomy was used to analyse Twitter content, which provided very interesting data on the use of links or profile visibility, among others.

Type of Content Shared on Social Media
A content analysis of all posts was warranted to begin to establish the real activity of the official tourism social media accounts of the three destinations and the communication strategies implemented. Therefore, the content was first analysed according to the attitude deduced from the post, and it was noted that nearly half of the posts sought to provide information to the followers, questions were asked in 19%, and, to a lesser extent, queries were answered and thanks given.
Photographs were the most frequent type of content shared, and they were often accompanied by links to official tourism websites ( Figure 5). Computer graphics, which were a mixture of image and text, came in third place and were particularly used for events and other types of calendar activity. However, contrary to what might have been expected, videos were not placed in a top spot.

However, contrary to what might have been expected, videos were not placed in a top spot.  Similarly, it should be mentioned that many posts focused on nature (27.2%), and 11% focused on architecture. Monuments (10.2%) were also a central topic of the posts, along with history (4.1%) and religion (8.8%). Museums featured less (2.7%), despite being a major tourist attraction in many cities.
The data showed that over half of the posts referred to popular culture and traditions, an example of which would be the Fallas in Valencia or Holy Week in Andalusia, which were centre stage for longer periods of time in each of the social media analysed. However, gastronomy was also prioritized, and, as a main tourism attraction, in a great number of Spanish cities, it was covered by nearly 35% of the publications.
Regarding the types of tourism, most posts (58%) were on cultural and calendar aspects ( Figure 6). Likewise, coastal images, followed by beaches, the sea, and the sun were identified as the most commonly promoted aspects (13%). Just over 10% of the total posts analysed were about mountains or inland tourism. There were fewer posts with religious, sports, and culinary themes. The tourism industry should continue to promote tourist destinations using iconic and unique experiences, and this should incorporate native flora and fauna as well as distinctive built and natural attractions [3]. Each theme covered by the posts then had to be considered and analysed in greater depth. Many of the posts (37%) focused on places that could be visited within each of the destinations in question.

Just over 10% of the total posts analysed were about mountains or inland tourism. There were fewer posts with religious, sports, and culinary themes. The tourism industry should continue to promote tourist destinations using iconic and unique experiences, and this should incorporate native flora and fauna as well as distinctive built and natural attractions [3]. The study also analysed the number of times that new technologies were mentioned, and over 60% of posts included hashtags or referred to technologies such as "timelapse" in some way.
Hashtags were used to organise events and activities or to organise the information and curious facts about different events and traditions. Posts also recommended and retweeted some television programmes or other third-party content, particularly in Valencia.
A very important aspect to analyse was whether the posts were to do with events on the calendar, contained basic tourist information, or whether they were institutional or had nothing to do with tourism. Over half (60%) of the content studied was information of tourist interest. However, 20% referred to calendar activity. It is also significant that the same percentage was non-tourist information; in other words, the posts were, for example, "Good morning" updates.
In general, the activity of the three official accounts focused on proposing plans or providing information on scheduled events. They also directly recommended visiting a specific place in the The study also analysed the number of times that new technologies were mentioned, and over 60% of posts included hashtags or referred to technologies such as "timelapse" in some way.

They also directly recommended visiting a specific place in the selected regions. This means that the studied DMOs prioritise showcasing the tourist attractions over promoting their own brands as a destination and triggering emotional impacts to establish an in-depth relationship with the public. Furthermore, the posts mention tourist entities and other local or provincial tourism accounts. This may be because their mutual promotion of each other provides greater visibility.

Expert Assessment of the Promotion of Tourist Destinations
It was considered relevant to compare the data collected in the content analysis period with the assessments of experts whose day-to-day work means they are familiar with promoting tourist destinations through social media.
The experts began by assessing the importance of implementing a strategy to promote tourist destination using a particular type of media. They were asked why they considered the management of the social media profiles of the destinations to be essential. There was a great variety of answers, which can be seen in Figure 7.

They were asked why they considered the management of the social media profiles of the destinations to be essential. There was a great variety of answers, which can be seen in Figure 7. The following questions focused on the central area of the research, aiming to analyse the content. First, the majority of the experts agreed that video is the most effective type of content to share on the official profiles of destinations, which coincides with the forecast of the 12th Cisco Visual Networking Index [134], which stated that video would lead the way and would represent 70% of all Internet traffic in Spain by 2021, compared with 60% in 2016. However, they stressed that each type of content has to adapt to each social media platform.

Facebook was the social platform that the experts identified as being the most appropriate and effective when promoting tourist destinations. The academics also considered that in addition to information being offered on the available services, interactivity with the general public should be also facilitated and enhanced.
The professionals of the public sector also expressed their opinions on the most effective types of content to use according to the attitude of the message. It was highlighted that a suggestive attitude is the most optimal way to promote a place as a destination. Meanwhile, the comments of the private sector were more decisive. Even though they differed in that regard, they all expressed the same opinion: that experiences need to be enhanced by using a narrative style including feelings and experiences, for example, words such as happiness, thrilling, and daring.
The experts were encouraged to comment on the importance of sharing information from an official and specialist tourism blog through the official profiles of the destinations. Above all, both the academics and the Public Sector professionals considered that tourists are demanding more information on destinations to aid them in preparing their own travel plans, and blogs greatly help to create loyalty if useful information can be found there. Thus, blogs help to enrich the narrative and convert users into influencers based on their experiences.
An aspect in which interviewees from the private and public sectors coincided was that interactivity between the social media profiles of the destinations and their audiences is fundamental for their visibility. Thus, regarding the importance of the customer service channel, they considered it to be important but not vital.
Lastly, all experts interviewed agreed that tourist destinations use social media, above all, as an information channel to disseminate tourist content rather than a way of interacting with tourists to promote specific services of the tourist industry or deal with queries.

Data Obtained Using Online Tools
Within the period analysed, the images, links, and videos were the types of content with the most comments, reactions, and shares on Facebook (Table 4). Catalonia had the greatest number of followers with over two posts per day and a very strong weekly evolution (23%). The interaction was striking, with 0.87%, compared to the Facebook analysis of other communities. Catalonia nearly always posted images on Facebook, as was the case with the other regions analysed.
On Twitter (Table 5), Valencia was in second place with a large number of fans; however, it was the one that posted the most tweets, on average. The past performance of the account of Catalonia was very different; it obtained more "likes" per post even though it had fewer fans. Valencia was the winner in terms of the number of fans, but the fact that it did not obtain many retweets was remarkable. Retweeting from the official Twitter accounts of the three destinations was to local or regional tourism accounts, which could be to promote each other. The main type of activity conducted by all of them was, above all, showcasing plans through Twitter.
On Instagram (Table 6), significant engagement was achieved. In the same way as with the results obtained from the content and expert analysis, images were the content that best functioned on Instagram and, specifically, carrousel photos, which are several images put together in a single post, were used. Catalonia was the region that achieved the greatest engagement on Instagram with an average of 5035 likes and 24.1 comments per post.
Quantitative analysis allowed us to determine the content generation focus of these official tourism accounts and how they use their own icons or attributes to promote destinations. @ComunitatValenciana suggested the use of the hashtag #navidadenvivo or #semanasanta for their followers, while @CatalunyaExperience chose #Terresdelebre. The most popular hashtags are shown in the following Figures 8-10. All regions used hashtags chosen according their popularity and their coincidence with the names of specific cities, for example, #tarragona in Catalonia or #sevilla in Andalusia.

Thus, the great capacity of interactions to drive a destination brand is not being optimized. An association between interactions (likes and comments) and followers was predicted using the Chi-Square Test of Independence (α = 0.05). Since the p-value was less than our chosen significance level α = 0.05, we can reject the null hypothesis and conclude that there is an association between the number of followers and the total number of interactions (likes and comments).

Discussion and Conclusions
This research work provides a number of new insights into the field of destination management through social media, paying particular attention to image creation and promotion as well as stakeholder contribution. First, we revealed that social media effort is concentrated on showing, persuading, and attracting tourists to the icons and attributes of a destination. In some way, destination image is based on this and the social media content reproduces and enhances these features. However, tourist sites and monuments share centre stage with characteristic events and traditions. This finding is in line with studies by Cantos et al. [38] and Bregoli [47] that highlighted the cultural and natural heritage of a region as being fundamental attributes that define its identity and contribute to the formation of its image as a tourist destination. Moreover, special emphasis is placed on experiences, how to enjoy the destination, and the ways in which to do this, depending on who the tourist is (familial, focused on nature, etc.). Consequently, the first hypothesis was validated, giving further support to previous literature results. Baloglu and McCleary [14] highlighted these components as being key factors in the destination image, and more recent research works showed that these factors make up the core of the content on social media [17,18,22,30].The value of events was also suggested by Ghazali and Cai [6], and Pike [35] drew the same conclusion about experiences as this study.
Second, the content analysis and statistical correlations support hypothesis 2. Social media platforms are interactive and dynamic, and they allow destinations to manage their image [15,68]. The content producers are aware of the strategic contribution of social media for their image, and they try to generate useful content for tourists. The empirical analysis provided evidence that more than 20% of the content shared is focused on proposing plans or providing information about scheduled events. We found that the number of followers, as a direct consequence of attractive content, rather than the number of posts, is not a major factor in whether a positive relation with interactions and interest in the destination on their social media is attained. This issue agrees with the findings of Sanders and Stappers [68] and Luo and Zhong [72] regarding the types of social media content that ensure customer interest and positive effects on relations between users and brands,

This issue agrees with the findings of Sanders and Stappers [68] and Luo and Zhong [72] regarding the types of social media content that ensure customer interest and positive effects on relations between users and brands, thereby leading to greater levels of credibility and loyalty, but it also highlights that DMOs should be consistent in creating value in social media to create a positive image for all stakeholders [17,[66][67][68].
All of the abovementioned information also answers our first two research questions. This study provides a better understanding of how social media is used by destinations by identifying the main common topics and strategies of engagement with tourists.
It should be stressed that there were very similar behaviour patterns in the management of social media of the three accounts analysed. The accounts focused on places of interest in the image strategies; moments or events of special tourist interest; lifestyle attributes or motivations for tourists, such as biking, sailing, or gastronomy, and the use of words to link positive feelings related to travel. As a result of the content analysis, the interactions of the posts in social media were found to differ from what they could be; this has also been a common finding in other studies [18,71]. Referring to content shared by each official account, large numbers of photographs, banners, and images were found with a lot of reactions, comments, and shares. Despite this, videos were the type of content that stood out with regard to interactions, albeit to a lesser extent because much fewer were posted. Videos were the most frequently used type of content. According to the experts interviewed, they are the most effective type of content to share on the official profiles of the destinations. Furthermore, videos are the most reliable way to provide information and are relevant for users who browse the web [135]. It is important for the tourist destinations to continue working on good social media management practices due to their interactive capacity and the influence they have on tourist decision-making [71,77]. This finding is in line with Huertas and Marine-Roig [17], and it also highlights that DMOs should be consistent in generating valuable content in social media to create a positive image among all stakeholders.
Furthermore, the promotion of the whole destination overall should be further encouraged, rather than focusing on the cities separately, while the image continues to be decisive in the differentiation of these and is crucial for value creation. Regarding engagement, it was shown that tourists are motivated to participate when a destination offers a broader and more varied range of attractions and activities, the community interaction is higher, and the content is relevant for their interests and profile (style of travelling). Likewise, gaining tourist involvement through content related to destinations is suggested as an effective resource for building and promoting a destination's image. As result of this, attention should be paid to content generated by tourists on destinations' official accounts as well as outside of these [22].
These conclusions coincide with and complement those of Stepchenkova and Li, [7], because they reinforce the identification of key issues for tourists related to destination choice. Moreover, in line with Huertas and Marine-Roig [17] and Leung et al. [15], it should be emphasised that being present on social media is a great way to promote destinations at a very low price. In any event, this study, as also stated by Usakli et al [19], shows that destinations are still facing challenges in using social media management to showcase their potential and achieve greater success with their strategies. The analysis allows us to conclude that further analysis is needed due the exploratory focus of this study.
The final finding is related to UGC (RQ4), and it is one of the main contributions of this study. Previous literature focused on how UGC is a key factor for managing destination image and general strategies [5,[83][84][85]136]. UGC is a fundamental way to involve tourists in forming image destination through social media [12,71,74,77,137]. It allows their needs and expectations [78][79][80] regarding their experience in each destination to be understood and indicates the types of content they value in social media from official accounts and DMOs in charge of promoting destinations [21].
However, the extent analysis was carried out on collaborative and external platforms, which means sources outside of destinations' official accounts. This is the main difference and the source of the novelty in the analysis of the UGC issue in this study. Tourists generate content for destinations' social media as result of posts proposed by DMOs. Currently, destinations are aware of content created by users [13,85], but they are not working hard enough on motivating tourists to contribute to the formation and improvement of a destination's image. This factor cannot be analysed separately, and an integrative and coordinated effort should be used as a brand strategy. As Hidalgo Alcazar et al. [136] discerned, "tourism destinations need to disseminate favorable experiences to tourists, and these experiences include advice and comments from other travellers" (p.162). However, as claimed in this study, the benefits from including evaluations and experiences of tourists on destinations channels can reinforce and improve the engagement with and attractiveness of destinations. Thus, this content becomes a source of information and recommendations since tourists use it to share their experiences [138]. Moreover, the content generated by users is actually the key to gaining more interactions [22], and this content is more reliable than a destination's own content [81]. To sum up, one of the keys to the promotion of a tourist destination is the content generated by users. Consequently, it is proposed that DMOs should strengthen and prioritise two-way communication with tourists to better promote their image. It possible to take a similar approach to that described by Roca [56], who recommended the use of a concerted effort to create a structured model for image promotion in order to obtain maximal results from social media.
Last, but not least, some reflections about stakeholders are presented. Stakeholders are a main issue of the initial focus of this study. Although tourism literature has widely discussed the roles of stakeholders and their capacity to construct a positive destination image [49,91,[100][101][102], this study introduced stakeholders' roles in the interactivity of social media. Moreover, the application of the triple helix model for the analysis of stakeholders provides a clear distinction from previous literature. The interviews carried out allowed us to answer RQ5. A better understanding of the crucial role of stakeholders in content creation was also obtained. Most research works have focused on the role of tourists as central stakeholders, but other groups involved in destination activity should be taken into account, especially if the destination image is being analysed [29,98]. Based on the results, different stakeholders are valuable sources of trust, and content generated by them could attract potential tourists and contribute to the promotion of a destination. An interesting insight drawn from the study is that all stakeholders seem to be related and, consequently, they do not have to be approached separately. For example, it appears that universities can be a key partner for the creation and promotion of a destination's image in collaboration with DMOs and can be used as a source of knowledge for tourists.
In short, this paper demonstrates that social media platforms are strategic tools for destination branding and image formation and promotion. However, the novel factor of this study compared with previous literature is the acknowledgement that stakeholders play a main role. Tourists are not the only group to take into account. DMOs should have a wide and holistic vision of stakeholders. Therefore, their identification should be aligned with their involvement in social media strategies to achieve the goal of differentiation through a destination's image. If social media has an impact through its content, user contributions could increase and destinations will be able to exploit their attractions (icons, events, experiences) further and improve their positioning in the minds of tourists. Further, the insights provided in this exploratory study demonstrate the challenges that DMOs face in social media management.

Practical Implications
This research work provides the main practical implications for destination image management. DMOs can better manage and differentiate their social media content strategy through useful content, and the reinforcement of icons from the destination contributes highly to the formation of an image. Likewise, based on experiences and connections between a style of travelling and the type of content can improve performance in terms of a destination's competitive advantage. User-generated content is essential for promotional and marketing activities, as it is an effective way to create trust in tourists' minds. However, the involvement of all stakeholders should be appreciated and taken into account to achieve a successful result for image promotion. The analysis of destination image and the understanding and management of stakeholders' contributions indicated that operational strategies should be established to improve a destination's image promotion and to establish a deep relationship with the public.

Limitation and Future Research Directions
The current study contributes to the importance of social media in destination marketing and image formation from the perspective of stakeholders in several ways. To delve into a better understanding of the phenomenon it could be suggested to include the visitor point of view.
It is likely that not all factors that influence the creation of the image of a tourism destination by visitors using social media management were included in the conceptual model of this research.
Third, the active role of social media and the benefits associated with its incorporation into marketing and communication strategies needs to be further examined, since the literature shows that companies have not achieved the full potential of social media, not to mention the limited research that has been done in the tourism sector [139][140][141].
In addition, despite the results of this exploratory approach with a mixed method, further studies are required.
Some additional areas of study are proposed. Future research could explore how visitors perceive tourist destinations through social media using surveys. This could provide the opportunity to establish a comparison between visitors and the public and private sectors. Secondly, future scholars could analyse the importance of the dimensions of process quality and the quality of results. For example, longitudinal research should emphasize the interactions that occur between the public and the social media of tourist destinations, as this could ultimately give more information about image creation. Social media allows effective communication of destination brands and the development of a relationship between users and these brands [34].
Finally, future studies might consider the association between image representation and other factors that could lead customers to decide to visit one tourist destination over another.
