A base bid is a control, not a complete explanation of the final CPC. Sponsored Products offers fixed and dynamic bidding, as well as placement and other applicable adjustments. The useful question is how much a particular ASIN can afford to pay for a click from a particular search intent.
Calculate the economic ceiling first
Deduct product cost, referral and fulfilment fees, and expected variable returns cost from attributable order revenue. If €12 remains before advertising on a €40 order, a ten percent click-to-order conversion implies a simplified €1.20 break-even cost per click. Customer acquisition may justify another threshold, but make that decision explicit.
Audit in sequence
Separate branded, generic, competitor and product targets. Export search terms, placements, bids, CPC, clicks and attributed sales for the same period. Identify whether a change came from CPC, conversion or order value. Test one material lever at a time, and inspect stock, price and Featured Offer status. Avoid turning off discovery from a very short zero-sales window.
