A listing that looks complete is not the same as a listing that's optimised. Amazon's search algorithm and your conversion rate respond to different signals — and most sellers optimise for one while ignoring the other. This checklist covers both: what Amazon's A9/A10 algorithm needs to rank your listing, and what shoppers need to click "Add to Cart."

Use this checklist before every product launch, after every major category change, and as a quarterly audit tool for your existing catalog. Listings decay — what ranked well 18 months ago often needs a structural rebuild today.

Title optimisation

Primary keyword in first 60 characters. Mobile truncation cuts titles after roughly 60–80 characters depending on device. If your main search term isn't visible in that window, mobile shoppers (now over 60% of Amazon traffic) never see it. Front-load the keyword, then add brand name, key attribute, and size/quantity.

Stay under 200 characters total. Amazon indexes approximately 200 characters of your title for search. Anything beyond that is wasted. Some categories cap at 150 characters — check your category's style guide in Seller Central.

Avoid keyword stuffing. Titles that read like a search term dump ("Dog Bed Large Dog Bed Washable Dog Bed Orthopedic Dog Bed Memory Foam") may index broadly but convert poorly. Shoppers scan titles in under 2 seconds — if yours doesn't read like a coherent product name, they scroll past.

Include the variant. If this is a child ASIN in a variation family, include the specific variant (size, colour, count) in the title so the correct version appears in search results.

Bullet points

Lead with benefits, support with features. "Sleeps cool all night — 3-inch gel memory foam distributes weight evenly" converts better than "3-inch gel memory foam construction." Every bullet should answer a customer question or objection.

Each bullet addresses a different concern. Map your bullets to the top 5 purchase decision factors for your product. For a supplement: ingredients, dosage, certification, taste/experience, guarantee. For electronics: compatibility, battery life, durability, setup, warranty. Don't repeat information from the title.

Include secondary keywords naturally. Bullets are indexed for search. Weave long-tail keywords and related terms into benefit-driven sentences. "Works with all standard crib mattresses (28" x 52")" naturally includes the dimension search term without forcing it.

Five bullets minimum. Use all available bullet points. Shorter bullet counts leave conversion on the table and can signal a thin listing to Amazon's algorithm.

Backend search terms

No repetition. Amazon indexes each word once across your entire listing (title + bullets + backend). Repeating "waterproof" in backend when it's already in your title wastes characters. Use backend exclusively for synonyms, alternate spellings, and terms you couldn't fit naturally into visible content.

250 bytes maximum. Not 250 characters — 250 bytes. Accented characters and non-Latin scripts consume more than one byte per character. Stick to lowercase, no punctuation, spaces between terms. Every byte counts.

No competitor brand names. Including competitor brand names in your backend terms violates Amazon's Terms of Service and can trigger listing suppression. Amazon audits these fields.

Use relevant terms shoppers actually search. Pull your backend terms from your Search Term Report, Brand Analytics, and keyword research tools — not assumptions. Include common misspellings, Spanish/alternate language terms if relevant, and complementary product terms ("goes with," "compatible with").

Images

Main image requirements: Pure white background (RGB 255, 255, 255), product fills 85%+ of the frame, no text overlays or lifestyle elements, no watermarks, minimum 1000×1000 pixels for zoom functionality.

Minimum 6 images in this order:

7th image as video placeholder. If you have product video, use the 7th slot. Video increases time on listing and correlates with higher conversion rates across most categories.

A+ content (Brand Registered sellers)

Lead with a hero banner that communicates your brand story and key differentiator in one image. This is the first thing shoppers see below the fold — make it count.

Comparison charts convert. Amazon's comparison module (showing your product vs. your other products) keeps shoppers within your brand family rather than bouncing to competitors. Use it on every A+ listing.

Feature modules with lifestyle images. Three to four modules highlighting specific benefits with imagery performs better than text-heavy layouts. Match each module to a bullet point for messaging consistency.

A+ content is indexed for search on some markets. While Amazon's official guidance varies, evidence consistently shows that A+ text content contributes to organic discoverability. Write it for humans but include relevant keywords naturally.

Pricing and Buy Box readiness

Competitive price check before launch. Being 15%+ above category average suppresses conversion regardless of listing quality. Run a competitive price analysis in your category before setting your launch price.

Maintain pricing parity across channels. If your product is cheaper on your own website or on Walmart, Amazon may suppress your Buy Box eligibility. Pricing automation helps, but audit it manually at least monthly.

Common mistakes that kill otherwise good listings

Flat file overwrites. Uploading partial flat files can overwrite clean content with blank fields on certain templates. Always maintain a master flat file and test on a single ASIN before bulk upload. This is a catalog control fundamental that most sellers learn the hard way.

Broken variation structures. Orphaned child ASINs, wrong parent-child relationships, and mixed variation themes (colour and size in the same family) cause listing instability, review fragmentation, and browse node issues.

Category mismatches. A listing in the wrong browse node loses relevant browse traffic and shows up in the wrong sponsored placement categories. Compare your browse nodes against top competitors for your primary keywords.

Stale content. Search behaviour shifts over time. Keywords that drove traffic 12 months ago may no longer match current search patterns. Compare your current title and bullet keywords against your most recent Search Term Report — divergence above 30% signals a rewrite is due.

Run this checklist before every launch and every quarterly catalog review. The brands that maintain listing quality systematically — not reactively — compound their organic rank advantage over competitors who only optimise when something breaks.
