When selling on Amazon, using the wrong keywords in your title, bullets, backend search terms, or PPC ads can lead to:
- Listing suppression
- Search term removal
- Ad disapproval
- Account health warnings
- Policy violations
Amazon strictly monitors certain restricted and prohibited keywords — especially those that make false claims, misuse trademarks, or violate compliance rules.
This guide covers the most important restricted keyword categories you must avoid.
1️⃣ Medical & Health Claims (Highly Restricted)
Amazon does NOT allow unverified medical claims unless your product is officially approved.
❌ Avoid Words Like:
- Cure
- Treat
- Heal
- Prevent disease
- FDA approved (unless truly certified)
- Guaranteed results
- Anti-cancer
- Pain relief (for non-medical products)
- Weight loss guaranteed
- Burn fat fast
Even phrases like:
- “Clinically proven”
- “Doctor recommended”
- “100% safe”
Can trigger suppression without proof.
2️⃣ COVID-19 & Pandemic-Related Claims
Amazon strictly restricts pandemic-related marketing.
❌ Restricted Examples:
- Kills coronavirus
- COVID protection
- Virus shield
- Anti-virus mask
- Prevent infection
Only approved medical sellers can use compliant wording.
3️⃣ Trademark & Brand Misuse
You cannot use another brand’s name in your listing unless you are authorized.
❌ Examples:
- “Better than Nike”
- “Apple compatible original”
- “Like Samsung charger”
Using competitor brand names in:
- Titles
- Backend keywords
- A+ Content
- Sponsored ads
Can lead to listing removal or legal complaint.
4️⃣ Superlative & Misleading Claims
Amazon restricts exaggerated or unverifiable claims.
❌ Avoid:
- Best in the world
- #1 product (without proof)
- Guaranteed results
- No side effects
- 100% risk free
Instead, use:
- “Top-rated” (if based on real reviews)
- “Customer favorite”
Stay factual.
5️⃣ Adult & Offensive Language
Explicit terms are not allowed in most categories.
❌ Includes:
- Sexual terms
- Vulgar language
- Hate speech
- Discriminatory language
Even indirect phrasing may cause listing suppression.
6️⃣ Weapons & Dangerous Claims
Restricted wording related to violence or harmful usage.
❌ Avoid:
- Weaponized
- Military-grade (unless certified)
- Explosive
- Tactical assault
Some categories require special approval.
7️⃣ Environmental & Certification Claims
You cannot claim certifications without proof.
❌ Restricted:
- Eco-certified
- USDA Organic (without certification)
- CE Certified (without proof)
- Energy Star approved
False certification claims can permanently suspend accounts.
8️⃣ Time-Sensitive Phrases
Amazon discourages promotional time-based language in listings.
❌ Avoid:
- Limited time offer
- Best price today
- Sale ends soon
- Free shipping (if not Prime-based)
Keep promotional messaging inside advertising, not product titles.
9️⃣ Guarantee & Refund Claims
Amazon controls return policies.
❌ Do NOT Include:
- Money-back guarantee (unless compliant)
- Lifetime warranty (without proof)
- No questions asked refund
Returns are governed by Amazon policy, not seller claims.
🔟 Backend Search Term Violations
Even if not visible, backend keywords must follow rules.
❌ Do NOT:
- Add competitor brand names
- Repeat keywords unnecessarily
- Use commas excessively
- Add irrelevant trending keywords
Backend misuse can silently suppress your ranking.
Examples of High-Risk Keyword Categories
| Category | Risk Level |
|---|---|
| Medical claims | Very High |
| Weight loss | Very High |
| Supplements | Very High |
| Competitor brand names | High |
