Search Term Wasted Spend Analysis and Negative Keywords

A significant chunk of your Google Ads budget may be flowing to irrelevant search terms you never noticed. Search term wasted spend analysis helps you pinpoint the queries that never convert, block them with negative keywords, and redirect your budget toward the searches that actually matter.

A search term is not the same as a keyword

A keyword is the target you want to trigger your ad. A search term is the exact phrase a user actually types into Google. When you use broad match, a single keyword can trigger hundreds of different search terms—and some of them may have nothing to do with your business.

How does wasted spend happen?

• Irrelevant queries trigger your ad and rack up click costs without ever converting.
• Intent-mismatched terms like “free,” “jobs,” or “what is” burn through your budget.
• Non-branded broad terms drive high spend with low conversion.

How to run a wasted spend analysis

1. Pull the search terms report (with clicks, cost, and conversion columns).
2. Isolate the terms with high cost but low or zero conversions.
3. Add the intent-mismatched ones as negative keywords.
4. Turn the high-performing terms into dedicated, targeted keywords.

Done in seconds with AI

Doing this analysis by hand can take hours. With Opus Growth, you simply tell Claude or ChatGPT to “find the search terms wasting money and suggest negative keywords.” The connector pulls the search terms report, spots the wasted spend, and presents its recommendations as a preview. Once you approve, it adds the negative keywords for you.

A solid negative keyword strategy

• Build shared negative lists at the account level.
• Use match types (exact, phrase, broad) deliberately.
• Revisit the report on a regular cadence (weekly or monthly).
