Is your biggest affiliate your most expensive leak?

Ranked by value: Solid Hybrid first (score 83, ROI +58%, payback 1.9 months, the hybrid deal shares risk and the traffic retains), Revshare Grinder second (score 42 but ROI +76% because the 35% GGR share means cost tracks value), Volume Monster last (score 8, ROI minus 90%, payback 30 months). Volume Monster: the problem is not one KPI, it is the deal. A flat €250 CPA on traffic where only 22% ever deposit again means you pay top rate for bonus tourists. 6% duplicates and 1.2% chargebacks on top. Fix: stop the campaign, claw back confirmed duplicates, and only restart on a 2nd-deposit-qualified CPA at half the rate. Revshare Grinder: quality is mediocre (30% second deposits, 27% bonus cost) but the deal self-corrects. Biggest lever: the rev share is on GGR while bonus cost runs high, so you pay commission on revenue the bonuses destroy. Shift the basis to NGR at renegotiation. Compliance: Volume Monster needs a fraud review before the next invoice (duplicates plus chargebacks plus 78% KYC pass). Nobody else flags. Portfolio: reallocate the Monster's budget to partners with Hybrid's profile. You are buying volume where you should be buying players.
