Three things, in order
of how much they cost you
1. Can Amazon read it
Words stuck together with no spaces, or separated by commas, can stop the whole field from working. It also checks you are under Amazon’s 250-byte limit.
2. What is wasting space
Repeated words, filler like “the” and “for”, singular and plural pairs, and words already in your title or bullets, which Amazon indexes anyway.
3. The fixed version
A cleaned keyword string, correctly spaced and under the limit, with the bytes you freed up shown so you know how much room you have for new terms.

Common questions
Should backend keywords be separated by commas?
No. Amazon says to separate search terms with spaces and that punctuation such as commas is not needed. Commas still use up bytes. The cleaned version this tool gives you uses single spaces.
How long can Amazon backend keywords be?
Amazon asks you to keep the Search Terms field under 250 bytes. Most letters and numbers are one byte each, but accented letters take two or more. Amazon staff have said to use one Generic Keyword field only, so the “Add More” button does not give you extra room.
Should I repeat words from my title in the backend?
No. Amazon already indexes the words in your title and bullets, and its guidance says not to repeat information that is already captured in other fields. Use the backend for words that are not on the page: synonyms, alternate names and spelling variations.
Does this tool suggest new keywords?
No. Good keyword suggestions need real search data, and this tool does not have it, so it does not pretend to. It checks that the keywords you already have are set up so Amazon can use them, and frees up space for new ones.
Do you see my keywords?
The check runs entirely in your browser. If you ask for the fixed version we receive your email and a short summary of the result, such as how many bytes you used, so we can follow up. We never ask for Seller Central access.
