Why keyword cleanup matters
Amazon advertising keyword lists often come from many sources: competitor research, auto campaigns, search term reports, browser extensions, manual brainstorming, and listing audits. If those terms are imported directly, campaigns can become noisy and hard to read. Repeated keywords, unrelated terms, trademark risks, and mixed intent groups make it difficult to understand whether performance problems come from traffic quality, listing conversion, price, or image quality.
This cleaner normalizes raw input, removes duplicates, filters negative terms, and formats the remaining list into Exact, Phrase, Broad, and long-tail groups. Use Exact for high-intent terms, Phrase for controlled expansion, and Broad for discovery when you have the budget and discipline to review search terms regularly.
FAQ
Should Exact, Phrase, and Broad all run at once?
They can, but small budgets are easier to manage with Exact and Phrase first. Add Broad only when you are ready to review search term reports and add negatives frequently.
