Why you need this tool.
Amazon's backend field is far smaller than sellers assume, and using it wrong costs you the indexing entirely.
Duplicate keywords
Amazon reads the terms as a bag of words. Writing a word twice adds nothing to indexing — it only burns bytes.
Prohibited and wasted terms
Brand names, ASINs, subjective claims like "best", and stop words are either a policy violation or never indexed at all.
Going over the byte limit
The 250-byte cap is the total across all generic keyword attributes, not per field. Go over and Amazon does not truncate — it indexes none of the field.
How it works?
Paste keywords
Paste your list or a Cerebro/KeySpy export as-is — volume and CPC columns are stripped for you.
Process
Deduplication, cleaning, and blocked word check run automatically.
See what was dropped and why
Duplicates, blocked words, stop words, subjective claims, ASINs, brands and plurals — every removal is reported with its reason.
Fill 249 bytes and copy
The packer fills the budget to the last byte, lists what did not fit, and hands you a one-click paste for Seller Central.
