Google relies heavily on Gemini to validate its ad ecosystem, saying the AI improves fraud detection while reducing false positives for legitimate advertisers. The numbers also show how quickly ad security is becoming an AI arms race.
Driving news. In its Ads Safety 2025 report, Google said it blocked or removed 8.3 billion ads worldwide and suspended 24.9 million advertiser accounts last year. More than 99% of ads that violate the policy are stopped before they are shown, according to the company.
Google also said Gemini helped:
- reduce negative ad placements by 80%,
- process 4 times more user reports than last year,
- and catch scams faster by better understanding the ad’s intent.
In numbers:
- 602 million Scam related ads have been removed
- 4 million accounts linked to the scam have been suspended
- 4.8 billion Ads are limited
- 480 million blocked or restricted web pages
- 245,000+ used publisher sites
- 35 policy updates made in 2025
In the US: Google said it has removed 1.7 billion ads and suspended 3.3 million advertiser accounts in the United States by 2025. Top policy violations include:
- Abusing an ad network
- Misrepresentation
- Sexual content
- Personal violation
- Dating and friendship ads
Why do we care. Strong AI-driven enforcement can now directly affect whether your ads perform well or get flagged. Google says Gemini improves accuracy and reduces false positives, which can mean less unexpected interference with legitimate products. At the same time, strong automated reviews mean that advertisers need to stay on top of policy compliance, as enforcement becomes faster and more effective.
However, this may mean a lot of work for advertisers as several advertisers in the UK and US have reported receiving multiple ad disapproval warnings without any real problems being detected.
How Gemini is changing the practice of law. Google says Gemini can analyze hundreds of billions of signals — including account age, behavioral patterns, and campaign activity — to identify bad intent before older keyword-based programs.
The company said that by the end of 2025, the majority of Responsive Search Ads were being reviewed immediately upon submission, with harmful ads blocked before they were served. Google plans to expand that capability to more formats this year.
Yes, but. Aggressive enforcement can be a double-edged sword for marketers, especially when false positives derail campaigns. Google says Gemini’s better understanding of nuance has helped reduce false positives — a key problem for brands that rely on ad runtime.
An important point. Google is making Gemini the center of ad security – both to stop the growing scams and to assure advertisers that law enforcement will never lose legitimate campaigns.
