Repeat order rate is the share of new customers who order again within a year (Shopify average ~28%). Accept gift is % of creators reached. Seed to affiliate conversion is % of seeded creators (those who accepted a gift) who post and join as affiliates. In any month, only some affiliates sell; the rest stay in the program and may sell later. UGC savings start a set number of months after usable creator videos arrive, since brands usually run both before switching off paid UGC.
Affiliate rate can't be higher than the accept rate.
