## Amazon search-term n-gram analyzer

Your search-term report hides patterns one term at a time. Paste it here and the tool rolls every term up into 1, 2 and 3-word phrases, so the words quietly draining budget — and the ones worth more — jump out.

### What an n-gram analysis actually shows you

An “n-gram” is just a word or short phrase. The tool takes every customer search term in your report, breaks it into its individual words, pairs and triples, and adds up the spend, sales and ACoS everywhere each one appears. So instead of scanning thousands of search terms one by one, you see that — for example — the word “cheap” shows up across 40 different terms and has burned $310 with zero orders.

That is the point: negating one search term fixes one term. Negating one wasteful _word_, once you can see it pattern across everything, fixes all of them at once. The flags help you triage, but the rule for negating is **irrelevance, not just a high ACoS**. “Negate?” means a word spent with no orders — check the terms, then negate the truly irrelevant ones. “High ACoS” means it converts but inefficiently, so lower the bid rather than cut it off.

Pair it with your target ACoS from the [break-even calculator](https://autron.ai/tools/acos-calculator) and you have a weekly routine for defending your margins.

FAQ

### Common questions

### What is n-gram analysis for Amazon PPC?

N-gram analysis breaks every customer search term into its component words (1-word, 2-word and 3-word phrases), then totals the spend, sales and ACoS for each. It surfaces patterns a term-by-term view hides — for example, that every search containing the word 'cheap' converts poorly, even across dozens of different terms.

### How do I get my search-term report?

In Amazon Ads, open Reports and run a Search Term report for Sponsored Products, or download a Bulk file. Export to CSV or copy the rows, then paste them in. The tool auto-detects the customer search term, spend, sales and orders columns.

### What should I do with the wasteful n-grams?

Add the worst offenders as negative keywords (negative phrase or negative exact) at the campaign or ad-group level. A single negative on a wasteful word can stop spend across many search terms at once. Re-check after a couple of weeks.

### Is my report data safe?

Yes. The analysis runs entirely in your browser — nothing is uploaded to a server. Close the tab and the data is gone.
