Sponsored Products Strategy and Optimization
Sponsored Products is the workhorse format: keyword- and product-targeted ads for individual ASINs that appear in search results and on product detail pages. Structure campaigns for control - separate automatic and manual campaigns, separate prospecting from harvesting, and consider single-theme ad groups (one product or tight product set) so bids and negatives can be managed precisely. Automatic campaigns are discovery engines: mine the search term report for converting queries, promote them to exact-match manual targets, and add non-converting or irrelevant terms as negatives.
Optimization levers include bid adjustments by placement (top of search, product pages), match-type strategy (broad and phrase for reach, exact for control), and negative keyword hygiene. Watch for the traps: judging a keyword on too little data, over-negating terms that drive assisted conversions, letting automatic and manual campaigns compete for the same query, and ignoring placement modifiers when top-of-search is expensive but converting. Also distinguish click-through rate from conversion rate - a high CTR with low CVR signals a listing or relevance mismatch.
Rule of thumb: give a target roughly 10 or more clicks before making a bid or negation decision, and move proven search terms from auto to exact manual in a dedicated ad group. Worked example: a search term with 15 clicks, 2 orders, and a $1.00 CPC spent $15 to earn 2 × $20 = $40 in sales, an ACOS of 37.5% - if your target ACOS is 30%, lower the bid or improve conversion before scaling.
