Why banned words matter
Amazon's A9 algorithm is unforgiving. Use the wrong word in your title or bullets, and your listing gets demoted, suppressed, or removed entirely. The worst part? Amazon doesn't tell you. You just notice your sales tank.
We analyzed 500+ top-performing Amazon listings and cross-referenced them with Amazon's official Style Guide updates from 2024-2026. Here's the definitive list.

Tier 1: Auto-suppression triggers
These will get your listing removed within 24 hours:
Tier 2: Demotion triggers
These won't remove your listing but will tank your search ranking:
Tier 3: Format violations
Not technically banned words, but Amazon will demote:

The bottom line
Amazon's algorithm is a black box — but the rules around language are clear. Stick to descriptive, factual, benefit-focused copy. Avoid superlatives. Let your product specifications speak for themselves.
A title like "Stainless Steel Water Bottle 32oz, Vacuum Insulated, Leak-Proof Lid, BPA-Free" will outrank "BEST Water Bottle - AMAZING Quality - #1 Rated!" every single time.
That's not opinion. That's the algorithm.
