If you run a site about poker, sports betting or online slots, you will hit the same wall sooner or later: AdSense revenue on those pages is low, or zero. That is not a bug. Google treats gambling as a restricted category on both sides of its ad business.
The publisher side: restricted content
Google's publisher policies separate content that is banned from content that is restricted. Gambling-related content, such as pages that promote online casinos, sports betting or lottery products, falls into the restricted group. AdSense can still serve ads there, but fewer advertisers are eligible to bid, so earnings fall. Pages that send visitors directly to gambling operators can lose Google demand entirely.
The advertiser side: certification
On Google Ads, gambling operators must hold a licence in each country they target and apply for Google's gambling certification before they can advertise. Meta has similar rules requiring written permission. The result is a smaller, licensed group of advertisers who pay high prices for the placements they can get.

Better options for gambling pages
- Affiliate programs with licensed operators, paid by revenue share or CPA. See our comparison.
- Specialist gambling ad networks that sell display, native and video to licensed operators. See gambling ad networks for publishers.
- Direct deals with sportsbooks and casinos for sponsorships, odds widgets and reviews. See where to find prospect advertisers.
A split set-up
Mixed sites, such as a sports news site with a betting section, often keep AdSense or another general network on news and evergreen pages, and use gambling partners only on the betting section. That keeps the account healthy and puts high-value advertisers where the readers are. If you are still applying, read AdSense application requirements first.
