Start with the qualifying action and commission basis. Is credit earned on a click, install, completed onboarding, new paid subscriber, renewal, or license sale? Is the percentage calculated from gross price, net revenue, or revenue after an app marketplace fee? Ask which plans, countries, and customer types qualify.
Then check attribution and payment: link or code, cookie or app attribution, first-click or last-click rules, attribution window, validation period, refund treatment, minimum payout, schedule, currency, and payment methods. Reporting should distinguish early interest from results that are actually commissionable.
Finally, read the rules on self-referrals, paid search, branded keywords, coupons, incentives, claims, screenshots, spam, and misleading comparisons. A program can reject traffic or commissions that break its terms. Save the terms you joined under and recheck them before a major campaign.
