Amazon Listing Linter — Character Limits, Byte Budget & Risk Words in One Pass
Paste your title, bullet points, description and backend search terms in one place. The linter checks the 75-character title rule, 500/250-character bullet limits, the 2,000-character description cap, the 250-byte search term budget, words that waste bytes because the front copy already indexes them, and a severity-ranked sensitive-word sweep. Everything runs in your browser — nothing is uploaded.
Paste any section to start — results update as you type.
Title: 75 characters or fewer in all categories from July 27, 2026 (media stays at 200). Bullet points: 500 characters hard limit each, 250 recommended so mobile doesn't fold them. Product description: 2,000 characters. Backend search terms: 250 bytes UTF-8 (3 bytes per CJK character). Words repeated between search terms and title/bullets are already indexed from the front copy — filling them again just burns bytes. Sensitive words are grouped by disease claims, guarantees, superlatives and more, ranked by severity; high-risk terms can trigger suppression. All checks run locally in your browser.
