Both findings come from Google’s 2025 Ads Safety Report and together reflect a broader change in enforcement. While more problematic ads are being stopped, fewer advertiser accounts are being suspended — suggesting a growing emphasis on blocking individual ads.

Google said the rise in blocked ads also reflects the growing use of generative AI by scammers to produce deceptive content at scale, with its Gemini models helping detect patterns across large campaigns and block them earlier.

The shift also mirrors a wider push by Google to integrate its Gemini models more deeply into its core products and infrastructure, including advertising, where the company is increasingly using AI to automate campaign creation, detect policy violations, and respond to emerging threats in real time.

Among the blocked ads and suspended accounts, 602 million ads and 4 million advertiser accounts were linked to scams, the company said.
