Google blocked a record 8.3 billion ads in 2025, up from 5.1 billion the year before, crediting its Gemini AI models for the jump

Google's 2025 Ads Safety Report found that AI-driven enforcement, particularly its Gemini models, caught more than 99% of policy-violating ads before they were shown to users, with 602 million blocked ads and 4 million suspended accounts linked specifically to scams. Despite the surge in blocked ads, advertiser account suspensions actually fell, a shift Google attributes to more granular AI enforcement targeting individual creatives rather than entire accounts, which the company says has also reduced incorrect suspensions by 80% year over year. Google said the rise in blocked ads partly reflects scammers using generative AI to produce deceptive content at scale, creating an enforcement arms race the company says its Gemini models are increasingly equipped to handle.
