Quick answer
Marketplace search can only match words in your listing. Paste your title, bullets and description, then your target keywords, one per line. The checker shows which phrases appear exactly and which are missing, with a coverage score. Add missing phrases naturally to bullets or the description, not by stuffing the title.
How to use this calculator
- Copy your full listing text from the product page or seller panel.
- Paste your target keywords, one per line.
- Add missing phrases where they fit naturally.
Formula
Coverage = keywords found ÷ keywords checked × 100
A keyword counts as found when the exact phrase appears in the listing text
This checks exact phrase matches. Marketplaces may also match plurals and synonyms.
Frequently asked questions
Where do I find keywords for my product?
Use marketplace search suggestions, competitor titles, and the search terms report in your ad console.
Does the backend search terms field count?
On Amazon, yes, hidden search terms are indexed. Paste them into the listing text box to include them.
Does keyword stuffing help?
No. It hurts readability and can break title rules. Cover each phrase once in a natural sentence.
