Duplicate Words Remover (Amazon Keyword Cleaner)

What this tool does

Paste a competitor’s title, bullets, and description. With one click, the tool removes duplicate words and noise so you get a clean list of unique keywords you can use in your title, bullets, description, or backend search terms. Nothing is uploaded—everything runs in your browser.

How to use it

1. Paste the listing text into the input box.
2. Choose your options:
   • Case: Original, lowercase, or UPPERCASE for the output.
   • Clean-up: Remove stopwords (common filler words), numbers, split hyphenated terms, and set a minimum word length.
   • Output: Keep order, Alphabetical, or By frequency (includes a frequency table + CSV download).
   • Exclude words: Add brand names or terms you don’t want.
   • Backend Search Terms mode: Shows a live 249-byte counter and a one-click trim button.
3. Click Remove Duplicates and then Copy Output.

Options explained

• Remove stopwords: Drops common words like “and, for, with” to tighten your keyword list.
• Split hyphenated: Turns “bag-strap” into “bag strap” so both words are counted and deduped.
• Exclude words: Use this to scrub competitor brand names or restricted terms.
• By frequency view: Shows which words occur most often so you can prioritize relevance.
• Backend mode (249 bytes): Counts UTF-8 bytes, not characters, and lets you trim to fit.

Best practices

• Do not include competitor brand names or restricted claims in your listing.
• Use “Keep order” when building titles; use “Alphabetical” for quick scanning; use “By frequency” when prioritizing terms.
• For backend search terms, avoid punctuation and stay under 249 bytes (spaces count).
• Mix exact keywords and long-tail variations in bullets and description for broader coverage.

Glossary

• Backend Search Terms: Hidden keywords (generic_keywords) used by Amazon to index your product.
• Byte counter: Measures UTF-8 bytes; some characters can take more than one byte.
• Stopwords: Common filler words that usually don’t help with search relevance.
• Frequency: How often a word appears in the text you pasted.

FAQs

What problem does this tool solve?

It condenses messy listing text into a unique, clean set of keywords—ready for titles, bullets, descriptions, and backend search terms—without duplicates or noise.

How does the 249-byte limit work for backend search terms?

Amazon evaluates the field in bytes (UTF-8), not characters. Spaces count. If the field exceeds the limit, Amazon may ignore it. Use Backend Mode to see the live byte count and trim to fit.

Should I remove stopwords?

Usually yes for backend search terms (to save bytes). For titles and bullets, keep words if they improve readability and conversion.

What’s the difference between “Keep order”, “Alphabetical”, and “By frequency”?

Keep order preserves the first-seen order (good for titles). Alphabetical sorts A→Z for quick review. By frequency ranks terms by occurrence and shows a downloadable table.

Can I exclude competitor brand names?

Yes. Add brand names or sensitive words to the Exclude box and the tool will remove them from the output.

Does the tool store my text?

No. Everything runs in your browser; no text is uploaded or saved.

Is this only for Amazon?

No. The logic works for Shopify, Flipkart, and other marketplaces when you need a clean keyword list.
