The advent of AI influencers in the product marketing space is changing the landscape of endorsement and consumption. The research conducted assesses the impact of endorser credibility, examining it for trustworthiness, expertise, and attractiveness; and the influence on purchase intent and consumer perception of AI-generated influencers by using Ohanian’s (1990) Source Credibility Scale [1]. It further evaluates whether AI influencers can offer a more feasible marketing solution, thereby replacing the human endorsers in digital marketing. A 5-point Likert scale questionnaire was given to 384 respondents from three private institutions; after that, a confirmatory factor analysis (CFA) and structural equation modeling (SEM) were employed to validate the model and test hypotheses. Research findings confirmed that the endorser’s credibility influences purchase intent significantly, with trustworthiness and expertise lending more credence than attractiveness. Additionally, it also indicated that AI influencers can have a larger impact on the market through credibility-building strategies—improving authenticity, being relatable, and engaging more with consumption patterns. The research findings contribute to changing the digital marketing space, addressing a critical gap in influencer marketing research, and highlighting how AI influencers can optimize purchase intent and consumption.
