On December 1, 2025, Google enacted a significant update to its Gambling and Games policy, targeting horse racing affiliate and comparison sites in the United States. This policy change marks a decisive step in the tech giant’s ongoing push to tighten control over gambling-related advertising, particularly concerning third-party promoters and affiliate businesses.

Immediate Impact on Affiliates

According to Google, the new rule prohibits the promotion of online horse racing content from aggregators, tipster platforms, and other third-party promoters via Google Ads. These affiliates had previously used paid traffic to direct users to various online racebooks and related gambling services. As part of the change, Google immediately revoked all certifications for horse racing aggregators, leaving them unable to continue advertising on its platform. Furthermore, applications for new certifications will no longer be accepted.

However, the policy does not extend to licensed operators. Companies legally authorized to operate in the U.S. and offer horse race betting under state pari-mutuel laws can still advertise through Google Ads, provided they meet specific requirements, such as adhering to responsible gambling guidelines and obtaining the necessary certifications.

This move is part of Google’s broader strategy to minimize high-risk, referral-driven gambling promotions, which often involve affiliate links and third-party content. By restricting ads from affiliates, Google aims to ensure that gambling ads remain more closely tied to licensed operators, thereby improving accountability and reducing the potential for misleading promotions.

The update is also consistent with a series of earlier policy shifts from Google, which in recent months has cracked down on affiliate-driven ads across the gambling sector. In February 2025, the company introduced stricter documentation standards for licensed gambling advertisers and ramped up its monitoring of affiliate content. This tightening of rules follows mounting concerns over deceptive marketing practices in the gambling industry.

What This Means for Affiliates and Operators

For affiliates who had relied on Google Ads to drive traffic to horse racing platforms, the policy change represents a major setback. Many of these websites must now reimagine their advertising strategies, potentially shifting focus to organic traffic or exploring opportunities in jurisdictions with more lenient advertising regulations. This shift could significantly alter the competitive landscape, benefiting licensed operators while weakening the market position of smaller affiliates.

In other parts of the world, Google has also expanded its advertising restrictions. A recent policy update saw the company extend its ban on offline gambling promotions to 42 additional countries, including Algeria, Egypt, and Morocco, to comply with local laws and prevent unauthorized promotions of physical gambling venues.

The new horse racing advertising restrictions come as part of a broader trend in the U.S. gambling market, where rapid changes in regulation and federal scrutiny of gambling ads continue to shape the industry’s advertising practices. In addition, a federal judge’s recent ruling against tech giants like Apple, Google, and Meta Platforms in California over illegal gambling promotions has further heightened the pressure on these companies to regulate gambling ads more strictly.
