so, i promised some data after testing two of the big ones. posted about it a while back but wanted to wait for the payout cycle to finish. my spreadsheet says betfair's commission structure is better for tier 2 geos, especially eastern europe. their backend lets you see per-country conversion rates, which is insane for optimization. but bet365's affiliate platform is a nightmare to navigate. like, genuinely awful. they pay slower and their reporting feels like it's from 2005. however, they have way more brand recognition, so the initial ctr on my native ads was almost double. ended up running both simultaneously for 90 days. attached a screenshot of the final roi comparison. betting programs are weird because the players stick around longer, so revshare can actually beat cpa if you're patient. lmao at anyone who says one is universally better.
