Brands Bribe Creators to Whisper Into ChatGPT's Ear. Correlation Is Not Causation. They Don't Care.

Brands are folding creator partnerships into their AI search strategies, hoping influencer content shapes what chatbots surface. OpenAI begins serving ads across 31 European markets on August 24. Four agency executives told Digiday that no direct link between creator campaigns and AI visibility has been proven yet. Kristina Coughlin, SVP at Trevant, reports clients now request AI visibility tracking in nearly every pitch.

This illustrates what I would call the Contamination Theory of AI Search. Large language models train on web content. If creators publish about your brand, that content enters the training corpus and subsequent retrieval. The mechanism is probabilistic influence, not guaranteed placement. You are essentially seeding the soil and hoping something grows. The fact that brands cannot prove causality but pursue the strategy anyway tells you everything about the primitive state of AI search optimization.
