Broad Match Drift Auditor

Broad match and AI Max stretch your keywords further than ever. Paste your search terms report with the keyword column and see exactly how far the matching drifts, what the far end costs, and which terms to negate. Nothing is uploaded; it all runs locally.

1 · Paste your search terms report, with the keyword column
Columns we look for: search term · keyword · match type · clicks · cost · conversions
or paste below. Either way, the report stays on your machine.
Drift = how little of the keyword survives in the search term.

Drift is a budget question, not a purity question

Modern broad match is genuinely good, and that's precisely why it needs auditing. When matching worked badly, waste was obvious. Now the drift is plausible: your wooden furniture keyword quietly funds shed bases, tarpaulins and memorial engraving, each only a few pounds a week, each defensible in isolation. Our n-gram analyzer catches the recurring words; this tool answers a different question: how far from your keywords is the money actually going? Seeing that a fifth of a campaign's spend lands on terms sharing barely a word with any keyword changes the conversation, both about negatives and about whether the keyword deserves broad match at all.

How to use this tool

  1. In Google Ads, open the search terms view, add the Keyword column, set 30 to 90 days, and download or copy the table.
  2. Paste or upload it above.
  3. Read the split: how much spend sits close to your keywords versus in far drift, and how much of the far end converts.
  4. Tick the wasteful terms, copy the phrase-match negatives, and add them to a shared negative list. Keywords with heavy unconverting drift are candidates for phrase match or tighter theming.

FAQ

Is my account data uploaded?
No. The report is parsed and scored entirely in your browser, it never leaves your machine and we never see it.
How do I get the keyword column in my report?
In the search terms view, add the Keyword column via the columns menu before downloading, or build the report in Report Editor with search term, keyword, match type, clicks, cost and conversions.
How is drift measured?
Word overlap between the search term and its triggering keyword, with light stemming so gardens matches garden. If most keyword words survive in the term it's close; if almost none do, it's far drift. It's a lexical measure, so judge intent yourself before negating.
Is far drift always bad?
No, sometimes broad match finds genuinely incremental converting queries that share no words with your keyword. That's why converting far-drift terms aren't pre-ticked. The problem is far drift with spend and nothing back, which is exactly what gets flagged.
Drift under control but performance still off? Match type is one lever of many. Our free audit checks them all.
