Google’s Generative AI Shields Users from Billions of Ads

In a significant victory for online safety, Google announced it blocked over 8.3 billion malicious ads in 2025 using its generative AI model, Gemini. This represents a fundamental shift from reactive security to proactive threat neutralization.

Ahead of the Curve with Generative AI

Gemini’s ability to understand ad intent rather than just matching keywords means that over 99% of violating ads were intercepted before reaching users—in many cases, before they even appeared in search results. This is particularly crucial for countries like Nigeria, where millions rely on Google daily.

Impact in Nigeria and Beyond

As scammers increasingly use AI to create convincing fakes, Google’s response offers a critical defense:

• Intercepting scams: 602 million scam ads targeting Nigerian users were blocked, along with over 4 million associated accounts
• Protecting legitimate businesses: Account suspension errors for genuine advertisers have decreased by 80%
• Combating AI-powered threats: Gemini now identifies and stops complex fraud schemes in under a second

Google has also implemented stricter verification measures, including ID checks and selfie verification, to combat fake identities among advertisers.

A More Secure Digital Future

The company suspended 24.9 million accounts, rolled out 35 policy updates, and handled four times more user reports than the previous year—demonstrating a comprehensive approach to online safety. By leveraging generative AI as its core defense, Google has raised the bar for digital security in Nigeria and worldwide.
