Is AI making ad fraud worse?
Yes, generative AI is lowering the cost of ad fraud: it can mass-produce plausible websites and apps, write fake reviews and create bots that browse more like humans. Verification firms such as DoubleVerify have reported sharp rises in new fraud schemes they attribute partly to AI. The same techniques also strengthen detection, so it is an arms race rather than a lost cause.
AI-written content farms can spin up thousands of made-for-advertising sites pages overnight, feeding traffic arbitrage schemes. AI-driven browser agents can mimic scrolling and reading, making bot traffic harder to separate from people with simple rules. Deepfake video and voice are also used in scam ads, a growing malvertising problem on social platforms.
On the defense side, machine learning helps fraud detection systems find subtle patterns across billions of events, cluster coordinated devices and adapt to new schemes quickly. Buyers should expect verification vendors to explain how their models catch AI-generated sites and agentic traffic, and should also decide how to treat legitimate AI agents that browse on a person's behalf.
