Google and the Impact of AI Gemini on Advertising Security

In its latest annual report, Google revealed impressive figures regarding online advertising security. Thanks to its artificial intelligence named Gemini, the tech giant managed to block 8.3 billion fraudulent ads over the past year. This AI has demonstrated remarkable efficiency, intercepting 99% of malicious ads before they even reached users.

This report highlights Google's considerable efforts to strengthen its defenses against advertising fraud. By using Gemini, the company was able to detect and eliminate threats at the source, which allowed for the removal of billions of ads and the closure of millions of fraudulent accounts. This approach has also reduced blocking errors for legitimate advertisers, ensuring a better user experience.

Impressive Global Figures

The statistics provided by Google reveal the extent of the problem and the measures taken to address it. In addition to the 8.3 billion ads removed, 24.9 million accounts were suspended worldwide. Among these figures, 602 million ads and 4 million accounts were specifically linked to scams.

In Europe, the effort has also been significant, with 1.6 billion ads removed and 2 million advertising accounts closed. These actions demonstrate Google's commitment to maintaining a safe and reliable advertising environment.

A Double Security Barrier

Gemini is not the only line of defense implemented by Google. The company also enforces strict identity verification for advertisers wishing to run ads on its platform. This preventive measure aims to weed out fraudsters early in the process, even before they can create an ad. This double security barrier helps make the ads displayed to users more trustworthy and secure.

AI Facing New Threats

In the field of cybersecurity, fraudsters have also adopted AI to create misleading ads at an unprecedented scale and speed. To counter this threat, Google relies on the speed and efficiency of Gemini. By the end of 2025, the majority of so-called "responsive" ads were analyzed and validated in real-time, allowing harmful ads to be rejected immediately. Google plans to extend this system to other advertising formats over the course of the year.

A Quick Response to Reports

Gemini also plays a crucial role when users report suspicious ads. The AI enables Google's teams to process these alerts much more quickly than before. By 2025, the number of reports that received a concrete response quadrupled compared to 2024. The few malicious ads that slip through the automatic filters are thus handled more efficiently, while human experts can focus on the most complex cases.

A Benefit for Legitimate Advertisers

The improvement in filter accuracy also benefits harmless advertisers. In the past, legitimate ads were sometimes mistakenly blocked due to overly rigid filters. Thanks to Gemini, which analyzes the true meaning of an ad rather than just its form, Google is able to better distinguish authentic commercial offers from disguised scams. By 2025, unjustified suspensions dropped by 80%, thereby reducing false positives and more effectively eliminating bad ads.

In conclusion, Google's AI Gemini has intercepted 99% of harmful ads before their dissemination, demonstrating the company's commitment to protecting users while supporting legitimate advertisers.
