Paste your keyword list
Copy your keywords from a spreadsheet, keyword research tool, or text file and paste them in.
Select separator type
Choose whether your keywords are separated by commas, line breaks, or spaces.
Remove duplicates
Click to deduplicate. The tool removes exact and case-insensitive duplicates (e.g., "Yoga Mat" and "yoga mat" are treated as the same keyword).
Copy the clean list
Copy the deduplicated keyword list and paste it into your Amazon backend search terms field or Etsy tags.

Amazon automatically indexes words in your product title, bullet points, and description. Repeating them in backend search terms wastes space. Use backend terms exclusively for keywords not appearing in your visible listing content.
Yes. Etsy allows 13 tags per listing, each up to 20 characters. Running your tag list through this tool ensures you're not wasting any of your 13 tag slots on duplicates.
