Amazon Banned Words & Restricted Terms (2026): What Gets Listings Suppressed | UltraWordCounter

Amazon Banned Words & Restricted Terms

One wrong word and Amazon can suppress your listing overnight, with no warning and no clear reason. Here are the banned and restricted terms that trigger it, why they get flagged, and how to catch them before you hit publish.

๐Ÿ’ก Quick answer: Amazon prohibits promotional claims (best seller, #1, free shipping, guarantee), unverifiable health and safety claims (cure, treats, FDA approved), and competitor brand names. It also gates whole categories, so terms tied to supplements, medical devices, pesticides, or hazmat can trigger an approval requirement. Any of these can get a listing suppressed, so scan your title, bullets, and description before you publish.

Why a single word can sink your listing

Amazon's systems scan every listing, and when they catch a prohibited claim they can suppress the listing, hide it from search, or block it from going live at all. The worst part is how quiet it is. There is usually no clear message telling you which word caused it, so you lose sales and ranking while you guess. Catching these words before you publish is far easier than untangling a suppression afterward.

Promotional claims Amazon bans

Amazon does not let you claim a ranking or a deal you cannot prove, or make your listing read like an ad. These are the most common triggers:

AvoidWhy
best seller, #1, top rated, bestUnverifiable ranking claims
free shipping, free giftShipping and promo claims belong in Amazon's system, not the copy
sale, discount, cheap, dealPricing claims that Amazon controls, not the listing
guarantee, guaranteed, 100%Promises Amazon cannot verify
eco-friendly, non-toxic (unqualified)Environmental and safety claims need real certification

Health and safety claims to avoid

Any claim that your product diagnoses, treats, cures, or prevents a condition is high risk, and often not allowed without approval. Words like cure, treat, heal, prevents, anti-bacterial, antimicrobial, FDA approved, and clinically proven can flag your listing or trigger a demand for documentation you may not have. If you sell anything touching health, tread carefully.

Restricted and gated categories

Beyond banned words, Amazon gates entire categories. Using terms tied to these can trigger an approval requirement before your listing can go live, which costs you time and sometimes money you did not plan for:

CategoryTrigger terms
Supplements & dietarysupplement, probiotic, collagen, dietary
Medical & drugFDA approved, medical device, thermometer, sterile
Pesticide & antimicrobialdisinfect, sanitize, kills germs, repellent
Hazmat & flammableflammable, aerosol, lithium battery, corrosive

Competitor and brand names

You cannot use another brand's name in your listing to ride their traffic, and you cannot use trademarked terms you do not own. Amazon treats this as a policy violation, and brand owners report it. Describe your product on its own merits instead.

This guide lists the words. It does not scan your listing.

Reading a list is not the same as checking your actual copy against it, and it is easy to miss a word buried in a bullet. The Amazon FBA Listing Optimizer scans your title, bullets, and description live, flags banned and risky words in red, and warns you when a term could send you into category approval, all before you publish. The preview at the top of this page shows exactly what that looks like. This page only counts; the tool does the checking.

What words are banned on Amazon? โ–ผ
Amazon bans promotional claims like best seller, #1, free shipping, and guarantee, unverifiable health claims like cure, treat, and FDA approved, and competitor brand names. It also restricts terms tied to gated categories such as supplements and pesticides.
Why was my Amazon listing suppressed? โ–ผ
Suppression is usually triggered by a prohibited claim in your title, bullets, or description, a restricted term, missing required attributes, or an image issue. Amazon rarely names the exact cause, so scanning your copy for banned words is the fastest first check.
Can I say "best seller" on Amazon? โ–ผ
No. "Best seller," "#1," "top rated," and similar ranking claims are prohibited in listing copy because they cannot be verified. Amazon awards its own Best Seller badge based on real sales; you cannot claim it yourself in the text.
What is a gated category on Amazon? โ–ผ
A gated or restricted category requires Amazon's approval before you can list in it, common for supplements, medical devices, pesticides, and hazmat. Using terms tied to these categories can trigger an approval requirement, so it helps to know before you write.
