Amazon Sponsored Products are cost-per-click ads: you choose targeting and a maximum bid, and you are charged when a shopper clicks. Amazon says Sponsored Products have no monthly or upfront fee and campaigns use advertiser-controlled budgets.
Budget control
Set a daily budget that matches your testing plan and monitor spend, clicks and resulting sales data rather than judging performance from impressions alone.
Targeting
Keyword and product targeting can be tested against genre, comparable titles and reader intent. Negative targeting can help reduce irrelevant spend.
Before advertising
A strong cover, description, price and retailer page matter because advertising can generate visits but cannot fix a weak product page.
Official sources
Platform fees and rules can change. Use the source links below when making a final publishing decision.
