Will Cleaning Search Terms Lower My CPC?
← Back to Why Did My Amazon Ads CPC Increase?
Quick answer
Search term cleanup is an Amazon Ads optimization practice that removes irrelevant or underperforming queries from your campaigns. When unprofitable terms stop consuming budget, less spend is wasted and average cost per click can stabilize or decline over time. The effect is not immediate and depends on auction competition, match types, and bid structure, but cleaner targeting often improves click efficiency and gives budget back to terms that actually convert.
Cleaning search terms is not a magic reset, but it is one of the most direct ways to remove budget pressure caused by low-intent clicks. If your CPC has been increasing, this process can create more room for profitable searches.
How search term cleanup affects CPC
Amazon Ads CPC rises when clicks become more expensive or when budget is spent on auctions that do not produce results. Cleaning search terms removes queries that are unrelated, too broad, or consistently underperforming. That can reduce the number of low-quality clicks your campaign pays for, which often brings blended CPC down even if individual auction prices stay the same.
However, lower CPC is not guaranteed. If remaining keywords are highly competitive, or if bids are already high, cleanup alone may only slow the increase.
Building a practical cleanup list
Start with the Amazon Ads Search Terms report and look for queries with meaningful spend but no sales, or spend that far outpaces return. A practical cleanup queue usually includes:
- Terms with clicks but zero orders over a relevant date range
- Queries with ROAS well below the campaign target
- Search terms that match the product loosely and waste clicks
A read-only tool like Amazon Negative Keyword Tool by Todoza can rank these terms by spend, clicks, sales, and ROAS before your team approves negative keywords. Over-filtering can reduce useful reach, so review the list before applying it.
When this matters most
Search term cleanup is most useful when CPC increases after broad campaign expansion, automatic targeting, or a long period without negative keyword maintenance. If rising CPC is driven mostly by seasonality or increased competition, cleanup can still help but may not fully offset market pressure.
