AI Tool for Amazon Listing Copy: Bullets, Search Terms and Checks

Write the title yourself first, in 75 characters or fewer, then use AI for the bullets, the Item Highlights and the backend search terms, giving it your product facts and a hard limit for each field. Afterwards, review what is live in Manage All Inventory, because Amazon's own AI can replace an over-length title.

From 27 July 2026, Amazon caps product titles at 75 characters, spaces included, in every category except media, and adds a separate, searchable field of up to 125 characters called Item Highlights. A title that used to carry brand, product, size, colour and three keywords now has to carry a lot less, and an AI tool that does not know the limit will happily hand back a 140-character title. Telling it the limit, and counting the result, is the whole discipline.

Where each piece of copy lives now

A listing has several fields, and each does a different job. Putting the right words in the right field matters more than polishing any single one.

Two caveats. First, the title and highlights limits come from Amazon's announcement of the 27 July 2026 change, which exempts media; open your category's listing template before you trust any other figure, mine included. Second, the search terms field has its own limit, measured in bytes rather than characters. Amazon's staff guidance puts it at 250 bytes, with plain letters and digits counting one byte each, so a list with accented letters may run out sooner than a character count suggests. If you write for several marketplaces, the tutorial on multichannel listings and their different rule sets shows how to keep them apart.

A main worked example: a stainless steel water bottle

Illustration only. Say a two-person homeware seller has a 750 ml insulated stainless steel bottle. Their facts, all verified from their own spec sheet and a test of the product:

• Brand: [your brand]. Volume 750 ml. Double-wall vacuum insulated, 18/8 stainless steel.
• Keeps drinks cold 24 hours and hot 12 hours in their own test at a stated room temperature.
• Fits most car cup holders (base diameter 7 cm). Leak-proof lid with carry loop. Powder-coat finish, five colours.
• Dishwasher safe for the bottle body but not the lid. BPA-free lid.

Their old title was 168 characters, so it is one of the listings Amazon would otherwise rewrite. They write the new title themselves:

[Brand] 750ml Insulated Water Bottle, Stainless Steel, Leakproof Lid

Counted with a six-letter brand name in place of the placeholder, that is 67 characters, inside the limit with room to spare. They do not hand title writing over to the tool, because it is the highest-stakes line on the page: it decides what the product is and what Amazon indexes first. They ask the tool for three alternative titles only so they can compare wording.

Then the prompt for the rest of the copy:

You are writing Amazon listing copy for a 750 ml insulated stainless steel water bottle.
Use ONLY the facts below. Do not add claims, numbers, certifications or comparisons that are not here.
Facts: [paste the list above]
Write:
1. Item Highlights: materials and recommended uses only, under 125 characters including spaces. Show the count.
2. Five bullet points. Each: a one- or two-word capitalised description, then one plain sentence of 100 characters or fewer.
3. Ten backend search term candidates (words not already in the title or bullets), one per line.
Rules: no medical or health claims, no "best", "number one" or "guaranteed", no competitor names,
no promotional words such as "sale" or "free shipping", no emojis, plain category wording.
Mark any fact you were unsure of with [CHECK].

Illustrative output the seller might get back, and what they change:

Item Highlights: 18/8 stainless steel, double-wall vacuum insulated, powder-coat finish. For commuting, the gym and car cup holders.   (98 characters)

Bullet 1: INSULATED - Double-wall vacuum insulation holds ice for up to 24 hours in our test conditions. [CHECK]
Bullet 2: HOT DRINKS - ...12 hours for tea or coffee...

The highlights line is actually 115 characters, not the 98 the tool reported. It still fits, but it shows why the count comes from a spreadsheet, never from the assistant. The assistant did correctly flag the temperature claim. The seller edits "holds ice for up to 24 hours" to "keeps drinks cold for 24 hours in our own test", because "holds ice" is a different claim they never tested. They also remove a bullet saying "perfect for hikers", which sounded fine but is an unsupported use claim, and replace it with the car cup holder dimension, which is a fact. That kind of edit, where an invented flourish becomes a real specification, is most of the human work.

Writing bullets that survive review

Amazon's selling guidance suggests opening each bullet with a one- or two-word description and following it with an explanation of 100 characters or fewer, written as a fragment. The patterns that fail are easy to recognise, and AI produces them readily when left alone:

• Claims you cannot support. "Clinically proven", "eco-friendly", "BPA-free" without a basis. Remove or document each one.
• Superlatives. "Best", "premium", "ultimate". They do not help the buyer and can trigger review.
• Price and promotion talk. "Great gift deal", "limited offer".
• Shipping or seller information. Belongs elsewhere.
• Repeated keywords. The same phrase stuffed into every bullet reads badly and does little.

A tidy bullet pattern for any product: benefit first, then the fact that proves it, then the number or measure. For example, "Fits car cup holders. The 7 cm base fits most standard holders, so the bottle stays upright." Notice the fact is checkable and the wording is plain.

A second illustrative case, to show the same approach on a different product. A small pet-supplies seller has a collapsible silicone dog bowl. The tool offers "Perfect for all dogs and all adventures", which the seller replaces with "Folds flat to 2 cm and clips to a lead or bag, so it travels in a coat pocket." The first sentence says nothing a buyer can act on, and the second gives size, method and use.

Backend search terms: what to put in, what to leave out

Search terms are the hidden keywords field. Their job is to cover words and phrases a buyer might type that are not already in your visible text. Repeating the title in the field wastes space. Treat these as the working rules, and check them against Seller Central's current help page, which is the authority:

1. No repeats. Amazon's staff guidance says information already in other fields, such as the title or brand, does not improve placement here, and that words should not be repeated within the field.
2. No other companies' brand names and no competitor terms. Your own brand already sits in the brand field.
3. Spaces, not punctuation. Separate words with spaces; the same guidance says semicolons, colons and hyphens are not needed.
4. No subjective or temporary words such as "best", "new" or "sale". The field is meant for generic words that help a buyer find the product.
5. Include real alternatives: synonyms, abbreviations and alternative names, such as "flask" or "tumbler" for a bottle.
6. Stay inside the byte limit. Plain letters and digits count one byte each; other characters may count for more, so a list that fits by character count may not fit by byte.

A prompt that gets useful suggestions without stuffing:

Here are my title and bullets: [paste]. List 15 words or short phrases a buyer might type
to find this product that are NOT already in that text. Group them: synonyms, use cases,
spelling variants. Do not include any brand names, claims, or words about price or quality.

For the bottle, the tool returns "flask", "thermos style", "gym bottle", "commuter", "sports", "tumbler" and "cup holder friendly". The seller drops "thermos style" because Thermos is another company's brand and a brand name that is not theirs, keeps the rest, and pastes them as space-separated words in the search terms field. They note the date and the list in a spreadsheet so they can compare against the search term report later. A related tutorial, how small sellers use AI for listings and reviews, covers where this fits with review replies.

Check the title length, honestly

Counting characters by eye does not work. Four ways to do it reliably:

• Paste the title into a spreadsheet cell and use =LEN(A1). It counts spaces, which Amazon also counts.
• Use a character counter in your browser or text editor.
• Ask the AI to count, then do not believe it. Language models routinely miscount characters. Use the spreadsheet as the judge.
• Treat Seller Central's own check when you save as the one that decides.

A small sheet with one row per listing is worth making: columns for ASIN, current title, =LEN() result, a pass or fail flag (=IF(C2>75,"SHORTEN","OK")), and the date checked. Run your whole catalogue through it once, and you know which listings need attention.

Reviewing AI rewrites in Manage All Inventory

Amazon now offers AI-powered title and Item Highlights recommendations, and its announcement says titles still over 75 characters after 27 July are switched to the AI recommendation gradually, while the listing stays active. Third-party tools can also push changes to your catalogue. Amazon names two places to look. In Manage All Inventory, find the listing, choose Edit from the drop-down and click View enhancements. If you are the brand owner, Review Listings Changes gives you 14 days to review, modify or approve AI recommendations before they are applied. A routine that takes ten minutes for a small catalogue:

1. Start with Review Listings Changes if you own the brand. Anything waiting there can still be edited before it goes live, so it is the cheapest place to catch an error.
2. Open View enhancements for each long-title listing and read the recommended title and highlights side by side with your original copy.
3. Check facts. Is the size, material and quantity still right? A rewrite that turns a "pack of 2" into a "set" can cause returns.
4. Check that nothing was added. A new claim, a certification or a comparison is a red flag.
5. Check variations. If the product comes in colours or sizes, open at least two child listings as well, because a change aimed at one listing is easy to miss on its siblings.
6. Restore if needed. Keep your approved text in a spreadsheet so an unwanted change can be reversed in minutes.

A realistic mistake: a seller accepts an automatic suggestion that changes "750ml" in the title to "25 oz" to match another market's habit. The bottle is the same, but the bullets still say 750 ml, and now the listing disagrees with itself. Buyers email asking which size they are getting. The fix takes two minutes, but only if the seller checks the live page after the change.

Another example: a three-bullet fix for a thin listing

Say a candle seller has a listing with a short title and three thin bullets: "Soy wax candle", "Smells great", "Gift idea". Their facts: 220 g soy wax, cotton wick, burn time about 40 hours in their test, six fragrances, hand-poured, lid included. They write the new title by hand ("[Brand] Soy Wax Candle 220g, Lavender, Cotton Wick, Lidded Jar", about 61 characters with a six-letter brand), then use the assistant for bullets. The first draft says "Smells amazing for hours". The seller changes it to "Lavender scent from lavender essential oil blend [CHECK: confirm supplier statement]" and then asks the supplier, because a fragrance description is a claim as much as a number. No supplier statement means no claim.

The finished bullets are specific: wax weight, wick type, burn time with the test condition, and care advice such as trimming the wick before each burn. The listing now answers questions that buyers would otherwise send as messages, which also helps conversion without adding a single keyword.

Title variants that fit in 75 characters

When you need alternatives, ask for them with the structure spelled out. A good template for most products is: Brand, product type, key attribute, size or count, colour or variant. Four illustrative examples across product types, each within 75:

• [Brand] Yoga Mat, 6mm Non-Slip TPE, 183x61cm, Teal
• [Brand] Ceramic Plant Pot 15cm with Drainage Tray, Matte White, Set of 2
• [Brand] USB-C Charging Cable 2m, Braided Nylon, Fast Charge, Black
• [Brand] Notebook A5, Dotted, 120gsm Paper, Hardcover, Green

Rewrite the lengths with your real brand name. Short brands leave more room; long brands may mean dropping one attribute and moving it to Item Highlights, which is exactly what the new 125-character field is for. Put attributes that buyers filter by, like size or material, in the title only if they identify the product, and everything else in the highlights.

A review loop that fits a small team

For a catalogue of fifty listings or so, this routine is realistic and cheap:

1. Keep one "facts sheet" per product in a spreadsheet: dimensions, materials, test results, certifications with document references, what is in the box.
2. Save the prompt above in a Claude Project or ChatGPT Project so every product is written the same way. The tutorial on writing product descriptions with AI covers the longer text.
3. Write the title yourself, then paste the facts and generate bullets, highlights and search terms.
4. Run the length checks in the spreadsheet.
5. Have a second person read the bullets against the product in their hands.
6. Publish. Come back after a few days and open Manage All Inventory to confirm what is live.
7. Look at your search term and conversion reports after a few weeks and adjust, rather than rewriting daily.

Expect the first listing to take an hour and later ones perhaps twenty minutes of your attention each, mostly in gathering facts and checking. The tool saves drafting time. It cannot replace knowing your own product.

Audit an old listing before you rewrite it

Often the quickest win is not new copy but removing what should not be there. Paste your current title and bullets into the assistant and ask it to act as a reviewer, not a writer:

Review this Amazon listing text against these rules: title 75 characters or fewer; no promotional
words; no unsupported superlatives; no medical or safety claims without evidence; no competitor names;
each bullet makes one point. List every problem as: location, quote, rule broken, suggested fix.
Do not rewrite anything I did not ask about. Text: [paste]

A realistic result for an older yoga mat listing might read like this (illustrative):

• Title, "BEST Yoga Mat Ever - Premium Non Slip Exercise Fitness Mat for Women Men Pilates Gym Workout Floor - FREE Strap": rule broken, superlative and promotion, and far over 75 characters. Fix: move "free strap" out of the title and into the box contents.
• Bullet 2, "Cures back pain and improves posture": health claim with no evidence. Fix: describe the cushioning thickness (6 mm) and leave outcomes out.
• Bullet 4, "Better than [competitor]": comparison naming another brand. Fix: delete.

Three problems, found in under a minute, each with a quote you can verify yourself. Then you write the new title by hand and ask for replacements for the flagged bullets only. This is a safer use of AI than a full rewrite because you are editing a listing that already has a sales history, and a smaller change is easier to undo.

Sums that tell you whether this is worth your time

Illustrative figures, so replace them with your own. A seller with 40 listings spends about 45 minutes per listing writing copy by hand, including checking: 30 hours. With a fact sheet and a saved prompt, the drafting falls to around 10 minutes per listing, while checking and entering the copy still take about 20. That is roughly 30 minutes a listing, or 20 hours in total, so about ten hours saved on the first pass, and more on every later product because the fact sheet and prompt already exist.

The cost side is small. A chat assistant on an individual plan is a flat monthly fee (see the vendor's pricing page for the current figure), and the character-count sheet is free. The real cost is the second-person check, which is worth keeping even though it is the part people drop first when they are busy. If a single wrong claim leads to a suppressed listing for a week, the cost of one missed review is bigger than a month of the saving.

Variants and bundles: where copy goes wrong quietly

Listings with colour or size variations are where a batch of AI edits can do harm. The parent carries shared text, and each child changes only an attribute. Two checks help:

1. Never write the child title with a colour that is not the child's colour. If the parent title says "Teal" and the child is "Black", a buyer sees a mismatch.
2. For bundles ("Set of 2"), write the count in the title and in the first bullet, then check the count in the box contents.

A quick check is a spreadsheet export of all child titles, a column for the attribute, and a formula such as =ISNUMBER(SEARCH(B2,A2)) to confirm the attribute appears in the title. Any row returning FALSE needs looking at.

What I would not hand to AI

• The title, until you have counted it yourself.
• Anything with a certification, safety, health or legal claim.
• Comparison statements about other brands.
• Compatibility lists, such as "fits model X". One wrong model number means returns.
• The final decision to publish.

Used as a drafting partner with a fixed fact sheet and hard limits, an AI tool helps you produce clean, consistent listings faster. Used as an autopilot, it creates a quiet stream of small errors that you only notice when the returns arrive.

Amazon listing and AI questions sellers ask

Does the 75-character limit apply to my existing listings?

Yes. Amazon's announcement says titles in all categories except media must be 75 characters or fewer, spaces included, from 27 July 2026, and titles still over the limit are switched to Amazon's AI recommendation gradually. Find your long titles in Manage All Inventory and rewrite them yourself before an automatic change does it for you.

Can AI-written bullets get a listing suppressed?

Amazon judges listing text by what it says, whoever wrote it. Health claims, other brands' names, promotional wording and superlatives you cannot back up are the first things to strip out. Read the content policy for your category and check the text against it before you publish, whether a person or a tool wrote it.

Should I let Amazon's own generator rewrite my listing?

Use it as a source of drafts, not as an automatic publisher. Brand owners get 14 days to review, change or approve Amazon's AI title and Item Highlights recommendations before they apply. Compare each one with your product facts, accept only what is correct, and keep a copy of the original text so you can restore it.

How often should I update search terms?

Review them whenever you change the product, add a variant, or see a search-term report show new buyer phrases. A quarterly check is a sensible habit for a small catalogue, with a quick look after any listing edit, because edits can overwrite fields you did not mean to touch.
