In 2024, Google blocked over 39 million advertising accounts, a figure three times higher than in 2023. This was achieved through an intensified effort against ad fraud. The company leveraged artificial intelligence, including large language models (LLM), to detect suspicious activities such as fake payment data and business impersonation. Most accounts were blocked before their ads could even be displayed, as reported by TechCrunch.

Google implemented over 50 improvements based on LLM to bolster security across its platforms. Additionally, over 100 experts from various divisions, including Ads Safety, Trust and Safety, and DeepMind, were involved in the review processes. They focused particularly on combating deepfake advertising that uses images of public figures. This resulted in the blocking of over 700,000 accounts linked to such ads, leading to a 90% reduction in complaints.

The highest number of accounts blocked was in the United States — 39.2 million. Major violations included fraud in the ad network, trademark abuse, false medical claims, personalized advertising, and gambling. In the U.S., Google also removed 1.8 billion ads.

The company paid special attention to election advertising — in 2024, it verified over 8,900 new advertisers and removed 10.7 million election ads. In total, Google blocked 5.1 billion ads, removed 1.3 billion pages, and restricted the display of an additional 9.1 billion ads.

Google acknowledges that the large volume of blocks raises questions about fairness, which is why it has established clearer communication with advertisers and an appeals mechanism that includes human review. The company believes that the decrease in harmful ads indicates the effectiveness of its new methods for detecting and blocking violations.
