Updated 18 October 2026. New guide to Amazon's 75-character title limit and item highlights field, with copy-paste prompts for every part of a listing and the AI tools now inside Seller Central.
To write an Amazon product description with AI, give the model your verified product facts and Amazon's current rules, then generate each part of the listing separately: a title of 75 characters or fewer, item highlights, at least three bullet points, a plain-text description and backend search terms. Separate prompts beat one big request because each part has its own limits, and the title rules changed recently.
Amazon's own Seller Central tools can also draft a listing from a few words, an image or a URL, and suggest fixes to live listings. Whoever writes the words, you are responsible for every claim, so run the result through the compliance checklist below. The rules come from Amazon's US help pages, checked on 18 October 2026; other Amazon stores can differ.
Amazon listing rules at a glance (US, October 2026)
| Listing part | Amazon's rule | What to tell the AI |
|---|---|---|
| Title (Item name) | 75 characters or fewer including spaces, except media. No promotional phrases, no word more than twice, no all caps. No exclamation marks, dollar signs, question marks, underscores, curly braces, carets, ¬ or ¦. | Brand, style, product type, key attribute, color, size or pack count, model number. Use numerals. |
| Item highlights | Up to 125 characters, shown below the title in search results and on the product page. | Comma-separated phrases for details that did not fit in the title. |
| Bullet points | At least three; limits vary by product type. No emojis, symbols such as ™ or ®, guarantees, ASINs, links, company details, abbreviations or all caps. | Capital first letter, a short header with a colon, a sentence fragment, no end punctuation. |
| Description | No HTML or other code, though line breaks are allowed. No contact details, prices, reviews or time-sensitive information. | Short plain-text paragraphs that answer buying questions. |
| Search terms | Under 250 bytes per Amazon's search pages, or Amazon Search ignores the field. One Amazon error page cites 200 bytes. | Lowercase synonyms; no brands, ASINs, "new" or "best". Stay under 200 bytes. |
| A+ Content | For ASINs registered to your brand. Basic allows 5 modules, Premium 7. No pricing, promotions, guarantees, competitor comparisons, links or shipping details. | Paragraphs of three sentences or fewer; spell out numbers under 10. |
What changed: 75-character titles and item highlights
Amazon's US title page now says titles "must not exceed 75 characters, including spaces," for all product types except media, in every store except Saudi Arabia, Egypt, Türkiye and the United Arab Emirates. The reason given is that mobile screens truncate long titles. Older guides that quote 200 characters no longer match Amazon's US help page.
To make room, Amazon added item highlights: up to 125 more characters of comma-separated phrases, shown below the title. Titles that break the rules may be corrected automatically or left out of search results, and title changes take 24 to 48 hours to appear.
For AI, the hard part is now choosing which facts fit in 75 characters and which move to highlights. Do not trust a model's own character count; check it with a counter or a spreadsheet LEN formula.
Amazon's own AI listing tools
As of 18 October 2026, Amazon's help pages and seller blog describe these generative AI features in Seller Central:
- AI listing creation. Under Catalog, then Add Products, Amazon drafts a title and attributes from a few words, a product image or a URL from your own website. A spreadsheet option creates draft listings in bulk, but only for new products. Amazon asks you to own or have a license for any URL content you use.
- Enhance. The Enhance tab in Manage Products lists listings that need work and, where available, AI suggestions for titles, bullet points and key attributes that you accept, edit or reject. Amazon first announced it as Enhance My Listing.
- A+ Content Manager. Modules with an "AI Ready" badge can generate text and images.
- Selling partner plugin. Announced at Amazon Accelerate in September 2026, it connects your listings and performance data to Amazon Quick and Anthropic's Claude, both in beta and rolling out gradually. Ask it to update one SKU's bullet points and it proposes the change, then waits for your approval.
Amazon's Enhance help page carries the key warning: AI-generated content "can include features and claims that were not in the listing's original content," and reviewing it is your job.
Copy-paste prompts for each part of an Amazon listing
Start each session with a facts block taken from your spec sheet, packaging or test reports, then run the prompts one at a time.
PRODUCT FACTS (use only these, add nothing):
Brand: [brand]
Product type: [e.g. insulated water bottle]
Key attributes: [material, capacity, dimensions, compatibility]
Variations: [color, size, pack count]
Proven claims and documents: [e.g. supplier lab test for X, or "none"]
Customer: [who buys it and why]
Keywords: [3 to 6 phrases customers search]Title prompt
Using only the facts above, write 3 Amazon product titles of 75 characters or fewer, including spaces. Order: brand, style, product type, key attribute, color, size or pack count, model number. Use numerals. Capitalize each word except short prepositions, conjunctions and articles. No promotional or subjective words. No exclamation marks, dollar signs, question marks, underscores, curly braces or carets. No word more than twice. Under each title, list the facts that did not fit.Item highlights prompt
Write item highlights for the chosen title: 125 characters or fewer, comma-separated phrases, no full sentences, using the most useful facts that did not fit in the title.Bullet points prompt
Write 5 bullet points. Start each with a short header and a colon, then a sentence fragment, for example "Wide mouth: 2.2 inch opening for adding ice". Begin with a capital letter, use no end punctuation and separate phrases with semicolons. Write numbers one to nine as words except in measurements, and put a space between a number and its unit. One unique benefit per bullet, each based on a fact. Leave out fabric content, care instructions and country of origin. No emojis, symbols, all caps, abbreviations, guarantees, links, competitor names or claims missing from the facts.Product description prompt
Write the description as 2 to 4 short plain-text paragraphs, 150 to 250 words in total, covering what it is, who it is for, how to use it and what is in the box. No HTML. No prices, availability, shipping offers, reviews, contact details, links or time-sensitive wording.Search terms prompt
Write backend search terms: lowercase words separated by single spaces, no punctuation. Use synonyms, spelling variants, abbreviations and uses not already in the title or bullets. Use the singular or the plural of a word, not both, and no repeats. No brand names, ASINs, temporary words (new, on sale) or subjective words (best, cheapest). Keep it under 200 bytes.A+ Content prompt
Write text for 4 A+ Content modules: a header of up to 8 words and a paragraph of no more than 3 sentences each. Spell out numbers under 10. Focus on features and benefits from the facts. No pricing, promotions, guarantees, shipping details, competitor comparisons, time-sensitive words or links.Compliance check prompt
Check this Amazon listing and list every problem with the exact words to change: title over 75 characters; banned characters; a title word used more than twice; promotional or subjective words; claims missing from the facts; disease, pesticide (antibacterial), environmental (eco-friendly) or certification claims (FDA approved, CE certified) without proof in the facts; prices, links, contact details or guarantees.

Example: a full listing for a fictional product
Northvale is a made-up brand. Facts given to the AI: insulated water bottle, double-wall stainless steel, 32 oz (946 ml), 10.5 inches tall, wide mouth with a 2.2 inch opening, screw-top lid leak-tested by the supplier, cold up to 24 hours in the supplier's lab test, powder-coated slate blue finish with a textured grip.
- Title (68 characters): Northvale Insulated Water Bottle, Stainless Steel, Slate Blue, 32 oz
- Item highlights: Double-wall insulation, wide mouth, leak-tested screw lid, cold up to 24 hours
- Bullets: "Cold up to 24 hours: double-wall stainless steel, per the supplier's lab test", "Wide mouth: 2.2 inch opening for adding ice", "Leak-tested lid: screw-top lid tested by the supplier", "Size: 32 oz (946 ml); 10.5 inches tall", "Textured grip: powder-coated slate blue finish"
- Description: The Northvale insulated water bottle holds 32 oz (946 ml) and stands 10.5 inches tall. Its double-wall stainless steel kept drinks cold for up to 24 hours in the supplier's lab test, and the screw-top lid was leak-tested by the supplier. The powder-coated slate blue finish has a textured grip.
- Search terms: flask canteen hydration hiking gym travel metal reusable cold drink sport jug
Note what the AI left out: no "leakproof", because the facts only say leak-tested, and no other brand names such as Hydro Flask, which Amazon prohibits in search terms.

Amazon product description AI FAQ
What is the Amazon title character limit in 2026?
Amazon's US help page says product titles must not exceed 75 characters, including spaces, for all product types except media. It applies in every store except Saudi Arabia, Egypt, Türkiye and the United Arab Emirates. Extra details can go in the item highlights field, which allows up to 125 more characters and appears below the title in search results.
Can I use ChatGPT or Claude to write Amazon listings?
Yes. Amazon offers its own generative AI listing tools, and its rules focus on what a listing says rather than which tool wrote it. Every claim must be accurate and provable, and the listing must follow Amazon's title, bullet, description and search term rules. Use the prompts in this guide, then check the output against the compliance checklist before publishing.
How many bullet points should an Amazon listing have?
Amazon's bullet point guidance asks for at least three and says character limits vary by product type, so check your category template for the exact maximum. Five focused bullets, each with a short header, one benefit and the fact behind it, work well for most products. Every bullet must carry unique information and should not repeat the title.
How long can Amazon backend search terms be?
Amazon's search help pages limit the Generic keyword field to less than 250 bytes and say the whole field is ignored if it is longer. An Amazon error page for the same field cites 200 bytes, so staying under 200 is the safe choice. Spaces and punctuation are not counted, and characters such as German umlauts can use two or more bytes each.
Can I use HTML in an Amazon product description?
No. Amazon's product detail page rules say not to use HTML, JavaScript or other code, with one exception: line breaks are allowed in the description. Richer formatting such as images, comparison charts and styled text belongs in A+ Content, which brand owners and authorized resellers can use for ASINs registered to their brand.
Do AI-generated product images need a label on Amazon?
If an image or video shows photorealistic AI-generated people, yes. Amazon requires the keyword contains-synthetic-performer in the file's metadata before you add it to listings or A+ Content, and then shows customers an indicator where applicable. Images of real people edited with AI tools, or images without people, do not need the tag.
