With frequent exposures of influencer false advertising and persona fabrication, “authenticity” has become an increasingly critical consumer demand. However, existing research employs inconsistent perspectives on “authenticity” (encompassing both consumer-perceived authenticity and influencer strategic authenticity) and remains fragmented, focusing narrowly on specific experiential dimensions such as positive emotions and social identity without systematic integration across the full customer journey. Therefore, this study adopts meta-analysis, systematically searching Chinese and English databases including Web of Science, Google Scholar and CNKI (2015–2026), and incorporates 170 effect sizes from 56 studies with 63 samples (
n = 22,563) to systematically examine the effects of strategic authenticity (SA) and perceived authenticity (PA) on the customer experience journey (affective experience, cognitive experience, physical experience, and social-identity experience). Publication bias tests (fail-safe
N > 5k + 10) indicated no significant bias. The results reveal that affective experience is more driven by strategic authenticity (ρ = 0.535), whereas cognitive experience (ρ = 0.591), physical experience (ρ = 0.355), and social-identity experience (ρ = 0.515) are more significantly influenced by perceived authenticity. Regarding influencer type moderation, virtual influencer SA exerts a stronger effect on social-identity experience (ρ = 0.574) than human influencer SA (ρ = 0.170, QB = 3.980,
p = 0.046); conversely, human influencer PA shows a stronger effect on social-identity experience (ρ = 0.571) than virtual influencer PA (ρ = 0.016, QB = 8.189,
p = 0.004). Regarding cultural differences, individualistic cultures exhibit stronger PA effects on physical experience (ρ = 0.419) and social-identity experience (ρ = 0.742); long-term orientation cultures show stronger SA effects on social-identity experience (ρ = 0.574). These findings contribute to the authenticity literature and offer actionable insights for influencer marketing practices.
