In 2025, Google's safety teams leveraged Gemini-powered tools to significantly enhance their ability to detect and stop malicious ads, catching over 99% of policy-violating ads before they were served. These advanced AI models analyze hundreds of billions of signals—such as account age, behavioral cues, and campaign patterns—to identify threats proactively, surpassing earlier keyword-based systems by understanding intent and spotting evasive malicious content.
Blocking Ads with Greater Precision
Gemini's proactive approach led to the blocking or removal of over 8.3 billion ads and suspension of 24.9 million accounts, including 602 million ads and 4 million accounts linked to scams. Complementing this technology is an expansive advertiser verification program that validates identities to prevent bad actors from entering the system, thereby building trust in the ads and businesses people encounter.
Working Faster Than Scammers
With bad actors increasingly using generative AI to create deceptive ads at scale, Gemini enables real-time detection and blocking. By the end of 2025, most Responsive Search Ads in Google Ads were reviewed instantly, with harmful content blocked at submission—a capability planned to expand to more ad formats. Gemini also improved processing of user feedback, allowing teams to act on over four times as many user reports compared to the previous year, enabling rapid neutralization of threats that slip through automated defenses.
Stopping Threats While Supporting Businesses
Gemini’s nuanced analysis goes beyond images and text patterns to distinguish credible offers from intricate lures. This precision helped reduce incorrect advertiser suspensions by 80% in 2025, balancing the removal of harmful content with support for legitimate businesses to keep their ads running.
As threats evolve, Gemini continues to keep Google's defenses ahead, ensuring safer ad experiences. Further details are available in the 2025 Ads Safety Report.
