Keyword & Tag Gap Analyzer

How it works

Describe your product → Paste your listing → See what's covered

We split your listing into words and short phrases. A concept counts as covered when its words appear together in one place — in any order, ignoring little words like 'for' and 'the', and treating simple plurals like 'teacher' and 'teachers' as the same word. We don't guess synonyms: 'mom' and 'mother' are different words to us, so add other wordings if you use them. When words are close but we can't be sure — different accents, words split across different parts of your listing, or similar words that can mean different things — we say Check this instead of guessing.

Plural rules and little words like 'for' and 'the' work in English only. Other languages are matched word by word, and some writing systems get Check this instead.

This tool analyzes up to 500 characters of a title, 200 per tag, 1,000 per keyword field and 20,000 of a description. These are limits of this tool, not of any platform.

Everything you type stays in your browser. Nothing is uploaded, saved, or sent to us.

What a possible gap means — and doesn't

A possible gap means you told us this idea matters and we couldn't find it in the parts of your listing you pasted. It doesn't mean those words would help your listing appear in search.

This tool doesn't research keywords, use search data, look at other sellers' listings, or predict rankings, traffic or sales.

This counts the concepts you entered. It isn't a score, and it can't predict how a listing will do in search.

We show a platform's published numbers only while SimpleLifeCalc's record of them is verified, so a number is left out rather than shown as current when it isn't.

Platform checks come from SimpleLifeCalc's verified record of each platform's help pages. The source and the date it was checked appear with each check.
