Key Facts:
- Google banned all horse racing affiliate sites and comparison ads effective immediately.
- Existing certifications for racing aggregators were revoked, and new applications closed.
- Licensed operators may still advertise their own racing product.
- The move aligns with Google’s tightening of gambling rules ongoing since 2024.
Google’s latest update to its Gambling and Games policy removes horse racing affiliates from every major part of the ad network. Advertisers promoting racing through aggregators, tipster portals, or comparison sites can no longer target US consumers through search, display, or video.
Google has revoked all existing certifications, effective immediately and shut the door on any new requests. This cut off a traffic source that many in the racing affiliate have come to rely on.
Licensed Operators Still Have Access
Google drew a bright line between licensed racing operators and third-party promoters. Operators, such as sports book brands and major racebooks, may continue to advertise their own horse racing products, provided they hold the appropriate gambling certifications and adhere to responsible gaming policies.
But affiliate style advertising, even when pointing to fully licensed and compliant partners, is now strictly prohibited. This layer of affiliates has historically helped those operators reach new bettors and driven significant market revenue.
Google Shifts Policy
Google has made several key changes to its policies pertaining to gambling, both in the US and around the world, over the past two years. But it has seldom provided public reasoning. Quietly, they’ve raised documentation thresholds for gambling-related ads, and most recently reclassified sweepstakes casinos as gambling rather than social gaming.
Analysts say this move likely reflects a reduced appetite for the higher-risk referral-driven acquisition model, forcing operators to undertake more of their own marketing, which will simplify compliance issues, especially in jurisdictions where the rules are changing rapidly.
US Market Only, For Now
Because the US market is the one most in flux from new regulations, Google started here and acted very quickly. However, it’s essential to note that Google continually reviews and rolls out country-specific updates, so the jurisdictions aren’t completely off the hook just yet, as the company experiments with what works.
Ironically, in several states, Google had earlier rolled out some expanded allowances for racing operators. Those slightly relaxed rules appear to have remained in place, but only for operators.
Conclusion
The broader point is that Google didn’t eliminate horse racing ads, but rather gutted the affiliate ecosystem that had grown up around them. Licensed operators can still use all of Google’s toolbox for availability, but those comparison sites and tipsters that at one time drove huge amounts of traffic have been eliminated.
For affiliates of all stripes, the December rule change isn’t a tweak; it’s a catastrophe. And unless Google decides to change course, going down the home stretch, the era of paid traffic racing aggregators might be finished for good.
