In June 2026, a notice about Amazon's new product title regulations shocked the cross-border e-commerce community. With only a little over a month left until it takes effect on July 27th, many sellers are still observing. Amazon means business this time: it's not just category restrictions or individual category tests, but a mandatory implementation across the entire platform. And it's not just "restrictions," but mandatory rewriting—decided by Amazon's AI on how your title should look.

Core of the New Regulation: The 75-Character Era Officially Arrives

Effective Date: July 27, 2026

Applicable Categories: All categories (except media products like books and audio-visuals)

New Title Length Limit: Product titles (including spaces) must not exceed 75 characters.

At the same time, Amazon has launched the "Item Highlights" feature, providing an additional 125 characters of display space for material, specifications, usage scenarios, core selling points, and other information. Highlight content also supports search keyword indexing and will appear directly below the title on the search results page and product detail page.

Note: Amazon officially states that the 75-character limit includes all symbols such as spaces, commas, and hyphens.

Why the Change? Amazon's Underlying Logic Has Changed

1. Mobile traffic forces title streamlining: Over 80% of Amazon's traffic comes from mobile devices. Traditional 200-character titles are often truncated to 75-80 characters on mobile, causing a lot of key information to be "eaten." Buyers often swipe away before seeing the full title, leading to a "hidden evaporation" of click-through and conversion rates.

2. Transition from "keyword search" to "AI semantic understanding": Early Amazon searches relied heavily on keyword matching, with sellers stuffing keywords into titles. Now, with the upgrade of algorithms like COSMO and Rufus and AI search capabilities, Amazon is moving from traditional text matching to semantic understanding. For AI, the more chaotic and complex the title, the more it affects the system's accurate identification of the product.

3. Comprehensive upgrade of traffic assessment standards—CDQ algorithm goes live: Amazon has launched a new Listing evaluation system—the CDQ algorithm—to replace the previous IDQ algorithm. It checks not just whether information is filled out, but also whether it's correct and logically consistent. CDQ scores directly determine the natural traffic allocation and exposure weight of ASINs.

Five Core Impacts on Sellers

1. Keyword stuffing space disappears completely, SEO logic is reconstructed.

2. AI automatic rewriting—risk of not being in control.

3. Brand sellers' 14-day review window is not a safe box.

4. Risk of ranking fluctuations for old links.

5. Multi-specifications/complex parameter categories are particularly affected.

Practical Guide: Six Things Sellers Should Do Now

1. Audit all store Listings.

2. Rewrite titles within 75 characters.

3. Master Item Highlights writing techniques.

4. Make good use of Amazon AI tools.

5. Focus on differentiation (avoid homogenization traps).

6. Optimize in line with CDQ scoring.

Timeline Before July 27th

Immediately export all ASIN lists, check the current title character count, and establish a modification priority list. Prioritize modifying titles and Item Highlights for high-sales, high-advertising ASINs. Check remaining Listings, verify AI-recommended versions, and continue inspections to ensure compliance.

Seize Opportunities: Crises Also Hide Bonuses

The new regulation is not just a crisis, but also opens a new window for sellers who are good at adapting: improved mobile click-through rates, more keyword layout opportunities, healthier industry competition, and more accurate AI understanding.

With just over a month left until the new regulation takes effect, it's a critical time to prepare for Prime Day. Sellers must actively adjust to take control of their fate or passively wait to see what "unified template" the AI will rewrite the title into.
