What is the best length for an Amazon title?

80 to 120 characters in 2026. Amazon truncates differently per device; keep the most important keyword in the first 40 characters.

How many backend keywords does Amazon allow?

250 bytes per ASIN. Lower-case, no commas, no duplicates of front-end terms. Include misspellings, synonyms, and translations if you ship internationally.

Should I use A+ content?

Yes. A+ content increases conversion 5-10% on average. If you have Brand Registry, use it on every ASIN.

Can AI rewrite my Amazon listing better than I can?

AI is faster, not necessarily better. AIAdKing uses Claude to propose rewrites that respect Amazon best-practice rules and your category's competitor patterns. You approve before publishing. Many sellers use it for first drafts and then edit.

Amazon listing optimization: the 2026 playbook

Title structure

Format: Brand + Primary Keyword + Differentiator + Size/Color. 80–120 characters. Primary keyword in the first 40 characters because mobile truncates.

Example: "Bracketron Universal Phone Mount, 360° Adjustable, Vent Clip for Car Dashboard, Black"

Bullet rules

Five bullets. Each leads with a benefit and supports with a feature. 200–250 characters each. No all-caps. No emojis. Use semicolons sparingly.

Description and A+ Content

A+ content beats plain description for conversion every time. Use the comparison-chart module to anchor your ASIN against your other ASINs. Use the brand-story module if you have Brand Registry.

Backend keywords

250 bytes per ASIN. Lower-case. No commas. No duplicates of front-end keywords (that wastes the budget). Include misspellings, synonyms, and (if relevant) translations.

Image stack

Seven images minimum. Image 1 must be white background per Amazon policy. Images 2–7: lifestyle, infographic showing features, scale image (in someone's hand), packaging, FAQ image (text on white). 1600px+ on long edge for zoom.

Drift detection

Listings change when team members edit them or when Amazon's category requirements update. Audit weekly. AIAdKing surfaces every drift from your last approved version so you can re-approve or re-edit.
