Amazon's 75-character title cap is not a future change. It is already running.
What happened (confirmed)
On June 10, Amazon announced in Seller Central that starting July 27, 2026, product titles in all categories except media (books, music, video) must be 75 characters or less, including spaces. Amazon's stated reasons: titles fully display on mobile, and they match length used by other online stores.
Amazon also added Item Highlights: 125 additional characters for materials, recommended use cases, and comparison details. Amazon says that field is searchable and visible with titles in search results and on the product detail page.
How enforcement works:
• After July 27, titles still over 75 characters are updated to Amazon's AI recommendation gradually
• Listings stay active while that happens
• Brand owners get 14 days to review, modify, and approve AI-generated title and Item Highlights recommendations in Review Listings Changes
• You can still edit titles and Item Highlights at any time in Manage All Inventory (View enhancements)

Why this matters
This is not a formatting cleanup. It is a forced rewrite of the highest-weight text field on the listing.
If you already cut titles and populated Item Highlights with the phrases you actually rank and convert on, you are fine. If you left it to Amazon, you may have already lost the exact-match language that carried organic rank and ad relevance.
Agencies watching catalogs after July 27 are reporting the same pattern: Amazon's AI defaults to generic, compliant language. It does not know which terms in your old 200-character title actually drove purchases. When those terms disappear, rank slides first. Then ad relevance and ROAS follow, and teams waste a week auditing PPC for a listing problem.
The math most sellers missed
You did not lose indexed real estate. You split it.
• Title: 75 characters (high weight, shopper-visible, truncated even shorter on mobile)
• Item Highlights: 125 characters (searchable, shown with the title)
• Combined: about the same 200 characters brands used to dump into one field
Leave Item Highlights empty and you took a real cut. Fill it and you moved keywords, you did not delete them.
Who it affects most
• Catalogs that still had 150–250 character titles on July 27
• Brands that never opened View enhancements or Review Listings Changes
• Non-Brand Registry sellers (no 14-day review window; the rewrite can land without your sign-off)
• Hero ASINs where one exact phrase carries rank, especially in industrial, compatibility-heavy, and variation-heavy categories
• Teams seeing ACoS creep since late July who have not diffed live titles against what they submitted
What CoreTrex would do this week
Do not rewrite the whole catalog in a panic. Fix the ASINs that pay the bills, then work down.
1. Pull a Category Listing Report and diff live titles against what you last submitted. Auto-edits do not send a helpful alert.
2. Open Manage All Inventory, View enhancements, and Review Listings Changes on your top revenue ASINs. Approve nothing Amazon proposed until you check it against Search Query Performance and converting ad terms.
3. Rebuild the 75-character title as: brand, core product noun, one differentiator, size/count if the category demands it. Front-load the phrase you rank for. The first ~60 characters have to stand alone on mobile.
4. Put the evicted detail in Item Highlights: compatibility, material, use case. Write it as a readable phrase, not a second stuffed title. No promo language, no all-caps, no keyword salad.
5. If ACoS moved after late July, check titles before you rebuild campaigns. A catalog change shows up as paid inefficiency.
Our take
Amazon handing the rewrite to its own AI is the part operators should not shrug off. The 75-character rule is the policy. The AI recommendation is Amazon optimizing for compliance, not for your conversion data.
We would rather spend a morning on the top 20 ASINs than spend September explaining a rank drop nobody logged.
Amazon already rewrote a hero listing, or you never opened Item Highlights? CoreTrex rebuilds titles and Item Highlights from your actual search and ad data, not from Amazon's generic suggestion. Talk to a strategist.
