Verified affiliate terms for 6 AI writing assistants and SEO tools: Writesonic, QuillBot, Surfer, Semrush, SE Ranking and Mangools. Each row is copied from the program's primary terms as recorded in AffilMap. The table is in no particular ranking.
Of these programs, 3 state a recurring payout (lifetime, ongoing or a set number of months), 2 are recorded as one-time and 1 does not state a payout period. 2 of the commission texts give an “up to” rate or amount, which is a ceiling rather than a guaranteed rate. Compare the Commission and Recurring columns together and check the notes below the table.
Rows come from each program's primary T&Cs or partner page, copied as recorded in AffilMap. They were last verified between 2026-09-06 and 2026-10-05 (each row shows its own date). AffilMap does not invent or estimate rates; open a program page for its source link.
