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.
“While these AI models are very, very important to us and have delivered a series of impressive improvements, we still have humans involved throughout the process,” said Alex Rodriguez, a general manager for Ads Safety at Google, in a virtual media roundtable.
The executive told reporters that a team of over 100 experts assembled across Google, including members from the Ads Safety team, the Trust and Safety division, and researchers from DeepMind. They analyzed deepfake ad scams involving public figure impersonations and developed countermeasures.
The company introduced technical countermeasures and over 30 ads and publisher policy updates last year. These moves helped suspend over 700,000 offending advertising accounts, leading to a 90% drop in reports of deepfake ads, the company claims.
In the U.S. alone, Google said it suspended 39.2 million advertiser accounts and took down 1.8 billion ads last year, with key violations tied to ad network abuse, trademark misuse, healthcare claims, personalized ads, and misrepresentation.
India, the world’s most populous country and the second biggest internet market after China in terms of users, saw 2.9 million account suspensions last year, Google said, making it the second-highest after the U.S. The company also removed 247.4 million ads in India, with the top five policy violations related to financial services, trademark misuse, ad network abuse, personalized ads, and gambling and games.
Of all the advertiser account suspensions, Google said it suspended 5 million accounts for scam-related violations.
Overall, the company removed almost half a billion ads related to scams.
Google also verified more than 8,900 new election advertisers in 2024, which saw half of the world’s population go to the polls, and removed 10.7 million election ads. However, Rodriguez noted that the volume of election ads compared to Google’s overall ad numbers was relatively small and would not significantly impact its safety metrics this year.
