Repeat a word from your title and you burned a byte for nothing. Paste your listing and keyword list. Get a clean space-separated string packed to the limit, with indexed words, duplicates, and regular plurals stripped, and the exact byte count reported.
Packed to 249 bytes · indexed words stripped · duplicates killed
The backend search-term field is invisible to shoppers and it is where the words you cannot fit into readable copy go to do their indexing work. You get one field, 249 usable bytes, and a set of rules most sellers never learned. The biggest leak is repetition: every word already in your title or bullets is already indexed, so retyping it in the backend is a byte spent on nothing.
The rest of the waste is subtle. Regular plurals get stemmed by Amazon, so "knife" already covers "knives" in most cases, and typing both wastes space. Commas and connecting words do nothing. Brand names and competitor names are prohibited. This tool runs your candidates through all of it and hands back a packed string plus a full account of what it cut and why.
Your title, bullets, and the words you want to rank for. It reads the visible copy first.
Already indexed, prohibited, wrong-intent, duplicate, and low-value words all get cut.
A clean space-separated string at the byte limit, plus what was cut for space and on purpose.
Your text is sent to our server, processed once by the AI to build the string, and not shared with anyone. We keep your email and a short usage summary so we can send you the results. Your listing text is not resold, published, or used to train anything.
The tool counts bytes, not characters, and standard letters are one byte each, so the count is reliable for plain English terms. Accented or non-Latin characters run two or more bytes, so if you include those, confirm the final count in Seller Central before saving. Value ranking is a judgment call the tool makes without your live search-volume data.
Your title and all five bullets so the tool can strip words already indexed there, plus any keyword list you want to rank for. If you only have keywords, paste those and it still filters and packs them, but it works best when it can see the visible copy too.
Amazon already indexes every word in your title and bullets. Repeating them in the backend field is the single biggest way sellers waste their 249 bytes. The tool pulls the indexed word set from your visible copy and leaves those words out, so every backend byte adds a term you were not already ranking for.
