Google's War on Deceptive Ads: 5.1 Billion Ads Blocked in 2024

Google has published its annual advertising security report, revealing unprecedented efforts to combat deceptive advertising practices. The tech giant blocked a staggering 5.1 billion ads and suspended over 39.2 million advertiser accounts throughout 2024. This dramatic increase in moderation activities stems primarily from emerging threats posed by generative AI technologies and a surge in fraudulent activities across the platform.

AI-Generated Celebrity Scams Lead New Wave of Fraud

A particularly concerning trend highlighted in the report is the rise of AI-generated fraudulent videos featuring celebrities. These sophisticated fakes frequently serve as bait for financial scams and cryptocurrency schemes. In response, Google implemented stricter information policies and blocked more than 700,000 accounts involved in creating advertisements with fake celebrity images.

To effectively combat these emerging threats, Google assembled a dedicated team of hundreds of specialists tasked with analyzing fraudster behavior patterns and developing robust countermeasures. This strategic approach yielded impressive results, with user complaints about such deceptive ads dropping by an extraordinary 90% during the year.

AI as Both Problem and Solution

While artificial intelligence tools have created new avenues for deception, Google has simultaneously leveraged AI as a powerful defensive technology. Throughout 2024, the company implemented over 50 improvements to its machine learning models, enabling faster identification of emerging threats—often before users even reported them. This proactive approach has significantly enhanced Google’s ability to prevent malicious content from reaching users.

Categories Most Affected by Ad Removals

Google’s report provides a detailed breakdown of removed ads by category:

Financial Services Lead Ad Removals

2. Gambling and betting services – 146 million ads removed
3. Adult content – 122.5 million ads removed
4. Health-related advertising – 104.8 million ads removed

Broader Platform Protection Measures

The company’s security efforts extended beyond individual advertisers to encompass partner sites within Google’s advertising ecosystem. The report documents the removal of 1.3 billion web pages and 220,000 websites for policy violations.

Special Focus on Political Advertising

A Shift from Reactive to Proactive Protection

The 2024 report signals a significant transformation in Google’s approach to advertising security—evolving from reactive responses to active user protection.
