Listing Word Checker
Paste your product title or description and instantly spot trademarked brand names, prohibited absolute claims, medical claims and restricted words that get listings suppressed on Amazon, Etsy and other marketplaces — before you publish. Runs in your browser.
⚠️ This is an automated helper based on a built-in list of commonly flagged words and brands — it is not legal advice and the list is not exhaustive. Rules vary by marketplace, category and country. Always confirm against the platform's own policies, and note that a flagged word isn't always wrong (e.g. "compatible with [Brand]" may be allowed if done correctly).
What this checks for
- Trademarks / brand names — using a brand you don't own (or even "for iPhone / compatible with Nike") is the #1 cause of takedowns and IP complaints.
- Absolute & superlative claims — "best", "#1", "100%", "guaranteed", "perfect" are restricted because they can't be substantiated.
- Medical / health claims — "cure", "treat", "FDA approved", "anti-bacterial" turn an ordinary product into a regulated one.
- Restricted promo words — "free", "sale", "% off", "cheapest" are often banned in titles and can suppress a listing.
