In 2025, Google reported blocking over 8.3 billion ads and suspending 24.9 million advertiser accounts due to rising malicious advertising activities. The majority of these ads were linked to scams, with 602 million specifically identified as harmful. Google attributed this success to its Gemini AI models, which analyze numerous signals to detect and block ads before they are published. The company noted a significant increase in the sophistication of scams, particularly those utilizing generative AI to create deceptive ads. Despite the high number of blocked ads, the suspension of advertiser accounts decreased, indicating a shift towards targeted ad blocking rather than outright bans. Google aims to enhance its ad safety measures further by expanding the use of Gemini across more ad formats. The company processed a record number of user complaints, which helped improve response times to suspicious ads. This ongoing battle against malvertising reflects the evolving tactics of cybercriminals in the digital advertising landscape.
