How to read these two records
Both rates are stated as percentages of customer payments, so the figures share a basis. They may still cover different plans, billing terms, and eligibility rules.
GPTZero pays recurring commission and Surfer SEO pays one-time, which typically matters more than the headline rate over a customer's lifetime. One of the two does not state a cookie window, so the attribution windows cannot be compared.
aifilliate publishes no ranking between GPTZero and Surfer SEO. Which program earns more depends on plan price, conversion rate, retention, and refund reversals in your own audience — none of which appear in published affiliate terms. Confirm eligibility, paid-search and trademark rules, and payout timing with each vendor before promoting either.
