Google 2025 ads safety report - Nigeria

Google 2025 ads safety report - Nigeria

Google has released its 2025 Ads Safety Report, revealing a fundamental shift in how we protect the internet using generative AI.

In 2025, Gemini-powered tools reached a new milestone, blocking over 99% of policy-violating ads before they could be seen by a single user.

While digital scams and sophisticated “AI-charged” threats continue to evolve globally, these defenses are providing a vital shield for the millions of Nigerians who rely on Google for reliable information and business growth.

The global report highlights several critical breakthroughs that are keeping the Nigerian digital ecosystem safe.

1. Stopping Scams in Real-Time (602 Million Ads Removed)

Scams remain a top concern for Nigerian internet users. In 2025, Google removed 602 million ads and suspended 4 million accounts specifically associated with scams. By using Gemini to understand the intent behind an ad rather than just keywords, we are catching deceptive lures that were previously designed to evade detection.

2. Protecting Nigeria’s Small Businesses from Incorrect Suspensions

For the thousands of Nigerian entrepreneurs using Google Ads to reach customers, a mistaken account suspension can be devastating. Last year, AI-driven precision helped Google reduce incorrect advertiser suspensions by 80%. This ensures that legitimate local businesses can stay online while enforcement remains laser-focused on actual bad actors.

3. Fighting “AI with AI” to Block Sophisticated Threats

Bad actors are now using generative AI to create deceptive content at scale. Google is meeting this challenge head-on by deploying Gemini to analyze hundreds of billions of signals—from account age to behavioral cues—to neutralize threats in less than a second.

4. Stronger Identity Verification (Selfie Checks)

To make it harder for scammers to operate, Google has strengthened its advertiser verification program. This includes new measures like selfie checks and immediate suspension for anyone providing false documents. This ensures that the people behind the ads Nigerians see are who they claim to be.

5. Responding 4x Faster to User Reports

Community feedback is vital for staying ahead of local threats. In 2025, Gemini helped safety teams act on four times as many user reports as in the previous year.

When Nigerian users report a harmful ad, Google’s systems can now process that feedback and neutralize the threat with unprecedented speed.

Google 2025 Ads Safety Report by the Numbers:

  • 3 billion+ ads blocked or removed in 2025.
  • 99% of policy-violating ads stopped before they were ever seen by a user.
  • 602 million+ ads removed for scam-related policy violations.
  • 09 million+ advertiser accounts suspended for scam-related activity.
  • 9 million advertiser accounts suspended.
  • 80% improvement in enforcement precision through AI.
  • 480 million+ web pages blocked or restricted.
  • 35 policy updates made to stay ahead of emerging tactics.
