Why n-gram analysis matters more in 2026

With AI Max for Searchand modern broad match, Google matches your ads to a far wider set of queries than your keywords suggest. That's often good — and sometimes quietly expensive. Individual search terms rarely have enough data to judge, but the words inside themrepeat. N-gram analysis aggregates cost and conversions by recurring 1-, 2- and 3-word patterns, so "cheap", "jobs" or "how to" reveal themselves as budget drains long before any single query would.

How to use this tool

  1. In Google Ads, open Insights & reports → Search terms, select your date range (30–90 days), and download or copy the table.
  2. Paste it above — we auto-detect the columns, whether tab- or comma-separated.
  3. Start with 1-word n-grams and at least 5 clicks; move to 2-word for phrasing patterns.
  4. Tick the wasteful patterns, copy the list, and add it as phrase-match negatives — ideally to a shared negative keyword list.

FAQ

Is my account data uploaded?
No. Parsing and analysis happen entirely in your browser — the report never leaves your machine.
Which columns do I need?
At minimum: search term, clicks, cost, and conversions. Extra columns are ignored. Currency symbols and thousands separators are handled.
Should I negate every zero-conversion n-gram?
No — check search volume and intent first. Low-click patterns may just need more data, and some assist conversions upstream. When in doubt, that's exactly what our free audit looks at.
