Amazon Banned Words List 2026: The Complete Guide for Sellers
Using the wrong word in your Amazon listing can get it silently suppressed — no warning, no email, just zero impressions. Here's every word and phrase that triggers suppression across Amazon, eBay, Walmart, and Shopify in 2026.

What happens when you use a banned word
Amazon doesn't always tell you when your listing is suppressed. The product stays in your catalog, your inventory is still counted, but it stops appearing in search results. You'll see impressions drop to zero while your dashboard shows everything is "active."
Silent suppression is the most common outcome, but banned terms can also trigger:
- Full listing suppression: Listing removed from search entirely until the term is removed
- Category review: Amazon flags the listing for manual review, which can take 1–7 days
- Account-level warning: Repeated violations accumulate and may lead to account suspension
- ASIN deactivation: For severe violations (medical claims, counterfeit-related terms), the ASIN is delisted
The tricky part: many of these words seem harmless. "Guarantee," "free shipping," and "#1" are all commonly used in everyday marketing copy. But on Amazon, they're policy violations.
Amazon Banned Words & Restricted Phrases
These terms apply to titles, bullet points, descriptions, and A+ Content. "Suppression" means the term will likely cause your listing to be removed from search. "Warning" means the term is discouraged and may be flagged during review.
| Word / Phrase | Risk | Why It's Banned |
|---|---|---|
| #1 | Suppression | Unsubstantiated ranking claims violate Amazon product listing policies |
| number one | Suppression | Unsubstantiated ranking claims violate Amazon product listing policies |
| best seller | Suppression | Only Amazon can award Best Seller badges — claiming this status is prohibited |
| guarantee / guaranteed | Suppression | Guarantee claims require substantiation and are restricted by Amazon policies |
| 100% guaranteed / 100% natural | Suppression | Amazon prohibits absolute claims paired with subjective qualifiers ('100% guaranteed', '100% natural', '100% effective'). Material composition like '100% cotton' is fine. |
| free shipping | Suppression | Shipping terms are controlled by Amazon — mentioning shipping in listing content is prohibited |
| act now | Suppression | Urgency-based pressure tactics are not allowed in Amazon product listings |
| limited time | Suppression | Time-sensitive claims create false urgency and violate listing policies |
| FDA approved | Suppression | FDA approval claims require official authorization and are strictly regulated |
| clinically proven | Suppression | Medical efficacy claims require clinical evidence and regulatory clearance |
| cures / treats [disease] | Suppression | Amazon's Disease Claims policy bans cure/treat/mitigate/prevent paired with disease or condition names. Pet 'treats' as a product name and benign uses of 'cure' are fine. |
| Emojis | Suppression | Emojis are not allowed in Amazon product listing content — use plain text only |
| cheap | Warning | Undermines perceived value and can trigger quality concerns during review |
| buy now | Warning | Transactional CTAs in listing content are discouraged by Amazon style guidelines |
| hurry | Warning | Urgency language is discouraged and may be flagged during listing review |
Backend keywords too: These rules also apply to your backend search terms field. Amazon's 250-byte limit for backend keywords is strictly enforced, and banned terms in the backend field can suppress the entire listing.
Special categories with additional restrictions
Some Amazon categories have even stricter rules:
- Health & Personal Care: No disease names, treatment claims, or "anti-" prefixes without FDA approval
- Supplements: Cannot claim to "boost," "enhance," or "improve" specific bodily functions
- Baby & Children: Cannot reference safety certifications you haven't obtained (CPSC, ASTM)
- Electronics: Cannot claim compatibility with brands you aren't authorized to reference

eBay Restricted Terms
eBay enforces terms through the VeRO (Verified Rights Owner) program. Counterfeit-related words are the most dangerous — they can trigger immediate listing removal and account suspension.
| Word / Phrase | Risk | Why It's Banned |
|---|---|---|
| fake | Suppression | Implies inauthenticity — eBay VeRO program strictly prohibits counterfeit-related terminology |
| replica | Suppression | Replica listings violate eBay counterfeit goods policy and may result in account suspension |
| counterfeit | Suppression | Counterfeit references violate eBay VeRO intellectual property policy |
| knockoff | Suppression | Implies the product is an unauthorized copy, which violates eBay listing policies |
| unauthorized | Suppression | Suggests the item is not legitimately sourced, creating trust and policy issues |
| #1 / guarantee / 100% | Suppression | Unsubstantiated claims are not permitted on eBay listings |
| free shipping | Warning | Shipping terms should be configured in listing settings, not mentioned in description text |
| act now / limited time | Warning | High-pressure urgency language is discouraged — eBay auctions already have natural urgency |
| Emojis | Warning | Emojis may render inconsistently across eBay platforms and are best avoided |
eBay item specifics matter: Banned terms in item specifics (structured attributes) are flagged just like those in the description. Since Cassini (eBay's search algorithm) weights item specifics heavily for ranking, getting these right is critical.
Walmart Marketplace Restricted Terms
Walmart has one unique rule that catches many sellers off guard: you cannot mention Amazon, Prime, or any competing marketplace in your listing content. Sellers who cross-list from Amazon often forget to remove these references.
| Word / Phrase | Risk | Why It's Banned |
|---|---|---|
| Amazon / Prime | Suppression | References to competing marketplaces are strictly prohibited on Walmart listings |
| cheap | Suppression | Walmart positions on value, not cheapness — use 'affordable' or 'great value' instead |
| best seller / #1 | Suppression | Unsubstantiated ranking claims are not permitted on Walmart Marketplace |
| guarantee / 100% | Suppression | Guarantee claims require substantiation — use specific warranty terms instead |
| limited time / free shipping | Suppression | Promotional urgency language and shipping references are not allowed in product content |
| FDA approved / clinically proven | Suppression | Medical claims require regulatory authorization documentation |
| Emojis | Suppression | Emojis are not allowed in Walmart Marketplace listing content |
Shopify & DTC Store Restricted Terms
Shopify stores aren't subject to marketplace enforcement, but the FTC and advertising standards boards still apply. These terms create legal liability and erode customer trust on your own storefront.
| Word / Phrase | Risk | Why It's Banned |
|---|---|---|
| cure / clinically proven | Suppression | Medical claims are prohibited for non-pharmaceutical products — violates FTC guidelines |
| FDA approved | Suppression | FDA approval claims require official regulatory authorization — misuse carries legal liability |
| buy now or miss out | Suppression | Aggressive scarcity CTAs erode trust on DTC stores — use value-driven CTAs instead |
| miracle | Suppression | Superlative claims without evidence are flagged by advertising standards |
| 100% guarantee / guaranteed results | Suppression | Absolute guarantee claims are risky for FTC compliance and consumer protection laws |
| cheap | Warning | On DTC stores, 'cheap' undermines brand perception — use 'affordable' or 'great value' |
| hurry / limited stock | Warning | False scarcity claims violate FTC truth-in-advertising guidelines unless factually accurate |
Cross-Marketplace Comparison
If you sell on multiple platforms, these terms are banned or restricted everywhere:
| Term | Amazon | eBay | Walmart | Shopify |
|---|---|---|---|---|
| #1 / number one | Banned | Banned | Banned | — |
| guarantee(d) | Banned | Banned | Banned | Banned |
| 100% [absolute claim] | Banned | Banned | Banned | Banned |
| free shipping | Banned | — | Banned | — |
| act now / limited time | Banned | — | Banned | — |
| FDA approved | Banned | — | Banned | Banned |
| clinically proven | Banned | — | Banned | Banned |
| cures / treats [disease] | Banned | — | — | Banned |
| cheap | — | — | Banned | — |
| emojis | Banned | — | Banned | — |
| fake / replica / counterfeit | — | Banned | — | — |
| Amazon / Prime | — | — | Banned | — |
The universal takeaway: unsubstantiated claims (#1, guarantee, 100%) and medical claims (FDA approved, clinically proven, cure) are restricted on virtually every platform. If you sell on multiple marketplaces, these should never appear in your base listing copy.
How to check your listings automatically
Manually scanning every listing for banned terms isn't practical, especially if you have dozens or hundreds of SKUs. Here are three approaches:
Option 1: Manual search (free, slow)
Open your listing in Seller Central, use Ctrl+F to search for each banned term one at a time. Effective for 1–5 listings. Impractical beyond that.
Option 2: Spreadsheet formula (free, medium)
Export your listings to CSV, use a SEARCH or REGEX formula to flag rows containing banned terms. Works for bulk scanning but requires maintenance as policies change.
Option 3: Automated scanning (recommended)
Use a tool that maintains an up-to-date banned terms database and scans your listings automatically. SellerAide's free Chrome extension does this in one click — navigate to any Amazon or eBay listing, click the extension, and get an instant compliance report with a 0–100 quality score.
