Amazon Title Rules 2026: 75 Characters, Highlights, Suppression

Last updated October 23, 2026 · First published November 5, 2026 · By Chad Norris

Disclosure: the author runs an Amazon advertising agency (Tide Flow) and has built a bulk title-rewrite workflow for client catalogs. The rules below come from reports of Amazon’s announcement and from Amazon-hosted pages where we could read them. See the disclosure.

In 2026 the rule that matters most is the length. Amazon announced a 75-character limit on product titles, including spaces, in every category except media, effective July 27, 2026, alongside a new 125-character field called Item Highlights for the detail the shorter title cannot carry. The short answer: rewrite your best sellers first to 75 characters or fewer with brand, product type and the one or two attributes shoppers filter on, move everything else to Item Highlights, and do not leave long titles for Amazon’s AI to shorten.

Reliability note

Amazon’s Seller Central help pages load behind a login and a script wall that our fetch tools could not read, and the original announcement was posted in the Seller Forums. Everything in this guide about the 75-character rule therefore comes from secondary reports (PPC Land’s summary and SellerEngine’s explainer, both read October 2026), which agree on the date, scope and mechanics. Details that are not in both are marked below. Use this as a briefing and verify in your own Seller Central before you upload anything.

The rules, side by side

Amazon’s own advertising guide had already advised “clear and concise” titles of about 60 characters for Sponsored Products readiness (best-practices guide), so the direction is not new even though the hard limit is.

What goes where

SellerEngine’s summary says Amazon treats the item name and Item Highlights as equal search inputs, so moving a keyword from the title to Highlights should not by itself remove it from search. We could not verify that statement against Amazon’s text, so test on a few listings and watch impressions in your reports rather than assuming.

A before and after (illustrative)

A fictional product, with lengths counted.

The rewrite keeps the brand, size, product noun, the strongest differentiator (stainless steel) and one feature. The cold-retention claim has to be true and supportable; do not copy claims you cannot back up.

Prohibited characters and phrases

Third-party summaries of Amazon’s title requirements list these as not allowed in titles: ! $ ? _ { } ^ and a few other decorative symbols such as ¬ and ¦, with # < > permitted only in specific contexts such as measurements or model identifiers. They also say titles must not contain promotional phrases, and give examples like free shipping and quality-guarantee wording, plus subjective claims like “best seller” or “top rated”. They recommend title case, numerals instead of spelled-out numbers, no ALL CAPS and no repeating the same word. These come from secondary guides (Seller Labs’ title rules is one); we could not open Amazon’s page itself, so the exact list may differ by category. Your category’s style guide in Seller Central is the authority.

What actually gets suppressed

Most reports tie search suppression to prohibited characters or content, not to length on its own, and the reporting we read says Amazon’s rollout does not suppress listings for being over 75 characters. It rewrites them. The practical risks are different:

• A bad AI rewrite. Reports say auto-revisions tend to strip useful information rather than restructure intelligently.
• A lost keyword. If the rewrite drops the phrase you rank on, you may lose impressions before you notice.
• A half-applied change. A flat-file edit that fails on one SKU leaves a mixed catalog.

Check the “Fix your listings” or listing quality views in Seller Central for flags rather than guessing.

How to rewrite in bulk

1. Export your catalog. SellerEngine’s guide points to the Category Listings Report for bulk updates and says edits typically process within about eight hours, with up to 24 to 48 hours before they appear everywhere (reported, not verified against Amazon).
2. Count characters in a sheet. Use a length formula and sort descending; fix the longest first.
3. Prioritize. Best sellers, seasonal and holiday items, high-margin items and titles far over 75 characters first.
4. Rewrite to a formula. Brand, then core noun and primary keyword, then the top differentiator, then variation attributes. Keep 68 to 74 characters as a target so one stray character does not break the limit.
5. Upload as a partial update, so only the title field changes and nothing else on the listing is overwritten. Use your category’s current template header.
6. Test Item Highlights on one or two SKUs first. Reports and our own testing notes describe the field being rejected in some categories with error code 100476 (attribute unsupported) or saving only when blank. If your category rejects it, enter it by hand through Manage All Inventory and “View enhancements”.
7. Re-check search terms and PPC. If a keyword left the title, confirm you still target it in campaigns; see how to structure Sponsored Products campaigns.

Where to find the keywords worth keeping

Do not guess which words the 75 characters should hold. Brand Analytics shows the queries that lead to your products and your share of them; the Search Query Performance guide covers how to read it. Your own search term report shows which queries sold. Keep the words that appear in both.

A short checklist before you upload

Run this against each rewritten title before it goes into a flat file:

Print the old and new title side by side in the sheet, with both lengths, so a reviewer can approve or reject each row in seconds. Keep the file you upload; if impressions drop on a SKU two weeks later, you will want the old title to restore.

Mistakes to avoid

• Shortening by deleting the keyword that carries your rank.
• Cutting variation attributes on child ASINs, which makes sibling listings look identical.
• Putting promotional words in Item Highlights because the field is new.
• Uploading to the whole catalog before one test SKU succeeds.
• Assuming a rule is the same in every marketplace. SellerEngine notes certain marketplace exceptions exist; check yours.

If you manage many listings

A catalog of a few hundred SKUs is a scripting job, not a typing job. Browse tools that help agencies run catalogs, keeping in mind that some tools listed there are made by the author, and keep a copy of every old title so you can restore one if impressions drop.
