Optimising Amazon Listings with AI: Titles, Bullets and a Compliance Check

AI can speed up Amazon listings, but the order has to be reversed from how most people do it: lock the product facts and the platform limits first, then generate copy candidates. Give a model one photo and a few keywords and it will happily invent a material, a performance claim or a target user. The copy looks complete; the risk is higher than before.

This playbook is built around the 2026 title change Amazon announced for the US marketplace. Per Amazon's notice, from 27 July 2026, outside media categories, titles must stay within 75 characters, with a new Item Highlights field of up to 125 characters. Rules keep moving; check the current category guidance in Seller Central before you edit.

Use the tool: the Amazon Title Checker checks a 75-character title and 125-character Item Highlights against the new rules, splits an old long title into both fields, and checks up to 500 titles at once.

Understand the new split: title identifies, highlights explain

Sellers used to cram brand, spec, material, use case and a pile of keywords into the title. The new structure pushes the title toward "the name that lets a shopper identify this product", with extra material or use-case detail moving into Item Highlights.

Think in three layers:

• Title: brand + product type + the single most important differentiating attribute, within 75 characters;
• Item Highlights: material, use case, or whatever a shopper needs to compare, within 125 characters;
• Bullet points: function, evidence, what's in the box, and the limits of use.

Those are character counts including spaces, not "words". Count them with a real counter after generation; never accept a model's verbal assurance that a string is under 75 characters.

Step 1: build a product truth sheet

Every SKU gets one table before any copy is written:

Fields with no evidence stay blank. Blank is not an invitation for AI to fill in; it's a note that someone owes you a document.

Step 2: generate title candidates, then check them mechanically

A workable prompt:

You are an Amazon listing editor. Use only facts present in the Product Truth Sheet below.
Generate 5 English title candidates.
Rules: each title max 75 characters including spaces; no promotional words, subjective superlatives,
competitor trademarks, or attributes not supplied; output the title and its exact character count.
Product Truth Sheet: ...

Then count with a spreadsheet formula or a script. Prioritise what a shopper needs to identify the product; don't sacrifice readability to fit another keyword.

Step 3: move what the title lost into Item Highlights

Item Highlights is not a second keyword box. It should answer "what else does a shopper need when comparing similar products": material and suitable environment, compatible models, size or capacity, which core parts are included.

Same rule: only facts from the truth sheet, and check the 125-character limit. Delete anything that repeats the title; use the space for new decision information.

Step 4: write bullets as evidence chains

Each bullet can follow one structure:

Verifiable attribute → what it does for the buyer → the condition or limit

Don't just write "Long-lasting battery". Reference the real test condition and figure; if there is no test condition, state only the confirmed capacity or usage guidance.

When AI generates the bullets, require an extra column naming the source field for each sentence. Any sentence that can't be traced to the truth sheet gets cut or sent back for confirmation.

Step 5: run compliance as a separate pass

Never let one prompt both write the copy and audit it. The second pass only looks for risk:

Review the listing draft below. For each sentence, flag:
1. attributes not present in the truth sheet;
2. absolute, medical or safety claims;
3. misuse of competitor trademarks;
4. numbers, units or compatibility that conflict with the truth sheet;
5. title or Item Highlights over the character limit.
Do not rewrite. Output location, why it's risky, and the suggested action.

The listing risks AI creates most often

• guessing material, colour names or accessories from the product photo;
• turning "works with" into "officially certified compatible";
• adding best seller, perfect, guaranteed;
• repeating the same word to cover search terms;
• rewriting a supplier's lab figure as a consumer usage promise;
• putting promotions, shipping or price in the title.

Pre-publish checklist

• title matches current marketplace and category guidance in Seller Central;
• both 75 and 125 character limits verified by an actual counter (the Amazon Title Checker does both);
• title, highlights, bullets and backend attributes don't contradict each other;
• every performance number traces to a document;
• variation colour, size and model line up with the child ASINs;
• images, box contents and text agree;
• nothing copied from a competitor listing or reviews;
• the truth sheet and final review record are saved for the next update.

Worked example: splitting one long title

Take a fictional kitchen brand, Bramblecut, and a lunch box listing as an example. The old title, written before the change, is 108 characters:

Bramblecut Lunch Box Stainless Steel Bento Leakproof Microwave Safe Kids Adults Office School 2 Compartments

The truth sheet for this SKU confirms: stainless steel body, silicone lid seal, two compartments, 1.2 L capacity, removable divider and folding spoon in the box. It has no test document for "leakproof", and the product owner notes the steel body must not go in a microwave.

The title prompt returns five candidates. The one the editor keeps is 59 characters:

Bramblecut Stainless Steel Lunch Box, 2 Compartments, 1.2 L

What a person changes along the way:

• "Microwave Safe" is cut. It contradicts the truth sheet, and the compliance pass flags it as a conflict.
• "Leakproof" is held back. With no test basis, it stays out until someone supplies a document.
• "Kids Adults Office School" is dropped. It is a list of search terms, not information that identifies the product.

Item Highlights then carries what the title lost, within 125 characters:

Silicone lid seal, removable divider and folding spoon included, steel body not for microwave use

The bullets pick up the evidence chain from there: capacity and compartments first, then what's in the box, then the care and use limits.

FAQ

Does the 75-character limit apply to every category? Per Amazon's notice it applies outside media categories, and rules vary by marketplace and category. Check the current guidance in Seller Central for your own listing.

Can I use Item Highlights for the keywords that no longer fit in the title? No. It works best as decision information a shopper needs to compare products. Repeating title words or stacking search terms wastes the space.

Should AI write and check the listing in one go? Keep them as two passes, as in Step 5. A prompt that wrote the copy is poor at finding its own invented claims.

AI's value here is fast structured candidates and contradiction-spotting. It doesn't take on your responsibility for accuracy.
