In paid advertising, does a brand achieve higher conversion efficiency by boosting creator-produced content compared to boosting brand-produced content, and to what extent is the difference driven by perceived trust and reduced ad skepticism?
Creator-produced content generally achieves higher conversion efficiency than brand-produced content in paid advertising, with the advantage substantially driven by greater perceived trustworthiness and reduced persuasion knowledge activation, though these effects are contingent on maintaining perceived authenticity and are moderated by influencer size, content-creator fit, audience brand attachment, and platform context.
Meta-analytic evidence indicates that creator-produced content achieves higher conversion efficiency than brand-produced content in paid advertising, with social media influencers demonstrating a small but significant advantage over brand-only advertising (d=0.16, p=.004). Field studies corroborate this finding, with influencer marketing generating more than twice the sales of sponsored advertisements in direct comparisons, and directed consumer-generated content yielding superior conversion rates and return on ad spend. The advantage is substantially driven by trust mechanisms: influencer trustworthiness significantly predicts purchase intentions (b=.41, p<.001), and user-generated content is trusted 3.2 times more than brand-created claims. Reduced ad skepticism operates through lower persuasion knowledge activation—user-generated content does not trigger defensive processing or negative affect, leading to higher purchase intention.
However, the creator content advantage is contingent on several boundary conditions. The effect is strongest for mega-influencers (d=0.33 vs. celebrities) but reverses for nano-influencers (d=-0.46), depends on high content-influencer fit, and disappears or reverses for consumers with high brand attachment who perceive influencer partnerships as norm violations. Platform context also matters: creator content advantages are robust on Instagram and YouTube but celebrity endorsements outperform influencer content on traditional media. Sponsorship disclosure presents a double-bind, with platform-initiated disclosures reducing trustworthiness while self-generated disclosures can enhance authenticity perceptions. Thus, while creator-produced content generally achieves superior conversion efficiency through trust and reduced skepticism mechanisms, effectiveness depends critically on maintaining perceived authenticity and appropriate matching of influencer characteristics to brand and audience contexts.
