The bid ceiling we use on our own affiliate campaigns: commission per order × conversion rate × 0.5, with worked examples from programmes we ran in 2026.
An 18% conversion rate still lost money on a 3% commission. What our own 2026 campaigns show about commission per order, conversion and return on ad spend.
AffWorth shows commission per order, the break-even bid and the real brand-keyword bid for each programme. 100 rows a day are free, no account needed.
