How to use it
Copy your title, bullet points, description and backend search terms from Seller Central. Paste all five bullets into the first box and they split automatically.
Title length, promotional words, ALL-CAPS, repeated words, bullet length and the 249-byte search-terms limit are checked live in your browser.
Click Get AI review for a score per section, the most important fixes, a shorter rewritten title and two improved bullets you can copy.
Amazon checks listings against style rules that differ by category, and some mistakes are silent. A title stuffed with promotional words can be suppressed. Backend search terms over the byte limit are not rejected with an error — the extra words are simply ignored, so you never find out they aren't working.
This analyzer covers the checks sellers most often get wrong: title length (many categories are moving toward shorter titles, so check your category's style guide), banned promotional claims like "best seller" or "free shipping", prices and emoji in the title, ALL-CAPS words, words repeated more than twice, bullets that are too long or all start the same way, and backend search terms measured in bytes rather than characters.
The instant checks are deterministic rules that run in your browser. The AI review reads your listing the way a listing specialist would — clarity of the product type, benefit-led bullets, and wasted search-term space. Your text is analyzed and not stored. Rules change and vary by marketplace, so always confirm the final details in Seller Central.
Most categories allow up to 200 characters, but many are moving to shorter titles and mobile search shows far fewer. This tool flags titles over 75 characters as something to check — the right length for you depends on your category's style guide in Seller Central.
Promotional or subjective claims such as "best seller", "#1", "sale", "free shipping", "100% guaranteed" or "limited time", plus prices, emoji, and special characters like ! $ ? ~ * (unless part of your brand name). Repeating the same word more than twice is also generally not allowed.
Amazon's search-terms limit is measured in bytes (249 in most marketplaces). Plain English letters are 1 byte each, but accented and non-Latin characters can take 2–4 bytes. Anything past the limit is silently ignored, so it's worth measuring in bytes.
No. Words already in your title, bullets or brand are already indexed, so repeating them wastes bytes. Use the space for synonyms, alternate spellings and use cases — and never competitor brand names.
No. The instant checks run entirely in your browser. If you request the AI review, your text is sent for analysis and not stored.
Yes, the analyzer is free with no sign-up. There is a fair-use limit on AI reviews per hour. zonfy's full listing generator — which writes the whole listing plus gallery images and A+ Content — is a paid plan.
