Surfer SEO vs Synthflow affiliate programs
Surfer SEO is an AI SEO tool and Synthflow is an AI agents tool. Both run affiliate programs. Surfer SEO lists 75%-125% of first payment (tiered CPA) through PartnerStack; Synthflow lists 20% through PartnerStack. One of the two does not state a cookie window, so the attribution windows cannot be compared. aifilliate records each program from a cited vendor source and does not rank the two.

What these terms mean in practice
A customer who stays subscribed for two years pays out on every qualifying renewal with Synthflow, and once with Surfer SEO. Which produces more depends on plan price and retention, neither of which appears in published terms.
What is not published
Anything below has to be confirmed with the vendor before either offer can be modelled. aifilliate records it as unknown rather than estimating it.
- Neither vendor publishes a cookie window or a payout threshold.
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.
Surfer SEO pays one-time commission and Synthflow pays recurring, 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 Surfer SEO and Synthflow. 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.
