A new Red Lab study has found that artificial intelligence-generated display ads can perform as well as, and in some cases better than, human-created ads when run in real advertising campaigns.

The research, which analysed more than 300,000 ads, over 500 million impressions and more than 3 million clicks, compared the effectiveness of AI and human creatives across several key sectors — including personal finance, food & drink and education — under identical targeting and campaign conditions.

According to the study, ads created by AI matched the performance of human-made ads in terms of engagement metrics such as click-through and conversion rates. Crucially, this totalised evaluation took place in live market environments, rather than controlled laboratory settings, underlining the practical validity of the findings.

Contrary to concerns that AI ads might generate low-intent or curiosity-driven clicks, the research found that quality of engagement remained strong. Call-to-action response and downstream conversion quality held up even at scale, suggesting that AI-generated creative can deliver meaningful results.

One of the most notable findings was that perceived authenticity — how human or artificial an ad appears — matters more than whether it was actually made by a human or by AI. Ads that looked more human-crafted tended to perform better than those that appeared overly artificial, regardless of their actual origin.

The study also highlighted that visual cues such as human faces play a strong role in driving trust and engagement, while overly polished or symmetrical imagery — often associated with AI — may reduce effectiveness.

Results varied by category. In fast-decision markets such as personal finance and food & drink, AI ads showed strong performance, while in high-trust categories such as education, responses were more measured.

Industry observers said the research underscores that AI is no longer just experimental in advertising but can be a competitive tool when guided by principles of authenticity and audience relevance.
