In these analyses, the data research follows how often gambling brands appear across leading affiliate websites, with a focus on betting and casino verticals in key Eastern European markets.

The top advertisers (gambling websites) on affiliate websites – Eastern Europe – Q1/2026

The first visible chart gives a broad Eastern Europe view of which gambling brands show up most often on affiliate websites.

• Cross-vertical visibility is the heart of this chart. It looks at how often brands appear across both betting and casino affiliate sites, which makes it easier to spot the names with the widest regional footprint.
• Global brands clearly have the upper hand in this comparison. The overall ranking suggests that large international operators are still better placed to secure broad affiliate exposure across several markets at once.
• Betano and Unibet stand out most strongly in the overview, while Superbet and a few regional names also stay visible.

The second visible chart narrows the view to betting-focused affiliate sites and shows a slightly sharper competitive picture. Here, the strongest brands are the ones that manage to appear consistently across several national affiliate ecosystems rather than only in one country.

• Betting-focused exposure drives this ranking. The chart is built around appearances on sports betting affiliates, so it reflects promotional reach and partner presence more than brand awareness alone.
• Country spread matters a lot in this view. Brands that show up across the Czech Republic, Hungary, Poland, and Romania naturally rise higher than operators with a more local or uneven footprint.
• Betano and Superbet come through as the strongest names in the regional betting picture, with Unibet also firmly in the mix.
