Google on Wednesday said it suspended 39.2 million advertiser accounts on its platform in 2024 — more than triple the number from the previous year — in its latest crackdown on ad fraud. By leveraging large language models (LLMs) and using signals such as business impersonation and illegitimate payment details, the search giant said it could suspend a “vast majority” of ad accounts before they ever served an ad. Last year, Google launched over 50 LLM enhancements to improve its safety enforcement mechanisms across all its platforms.
