Marketplace⚡Mastery #145: Amazon caps titles at 75 characters + AI image search + Walmart goes global

Hey sellers! Amazon is capping product titles at 75 characters, AI image search just landed in the app, and Walmart took its flywheel global.

🛑 Attention Amazon Sellers!

According to Amazon's help pages and Vendor Support, a new global title policy is expected across all marketplaces, including the EU, starting June 15, 2026: product titles capped at 75 characters. Not on Mobile. Desktop + Mobile.

Amazon is also adding an "Item Highlights" field (max 125 characters) below the title, so total indexable content stays at 200 characters, just split in two. This was already announced months ago.

New listings must comply from June 15; existing listings get a grace period until July 18, after which Amazon will suggest AI-generated titles for anything still too long, with 14 days to review, edit or accept.

It isn't fully live yet, but the updated policy pages are already showing up.

Existing listings won't be suppressed (for now) but CDQ (Content/Composite Data Quality) score penalties may follow after a 60 to 90 day grace period. Yet, this is unconfirmed.

Decide what earns a spot in your first 75 characters and what moves to Item Highlights, then roll it out across your whole catalog without breaking indexing. If you run hundreds or thousands of ASINs, start planning the bulk cleanup now, not on June 14.

I’ll use my friend’s Erez Sellerglory to bulk stream the process.

👉 Alexa for Shopping now designs custom merch. You describe an idea and the AI generates designs for products like T-shirts, sweatshirts and water bottles, produced and shipped through Merch on Demand with Prime-eligible delivery.

Designing is free and you only pay for what you order. It's live for all U.S. customers as of June 8, with more customizable products planned.

👉 Amazon built an AI image generator into search that creates product images from a shopper's description, refining them by pattern, color and texture with each new word.

Customers pick the image that best matches what they want and shop similar products.

For now it covers apparel and home goods, with more categories planned, alongside a new "Shop by Style" tool that builds AI-generated shoppable collages.

👉 Walmart takes its Amazon-style flywheel global expanding its higher-margin businesses, ads, memberships and marketplace, internationally, with Walmart+ launching in Canada, its first market outside the U.S.

The company is rolling out cross-border fulfillment plus systems to track tariff costs and taxes for third-party sellers shipping across the U.S., Mexico and Canada.

👉 Amazon is now selling its AI shopping tech to other retailers with the new AWS Agentic Shopping Assistant, which lets retailers launch their own conversational AI agents in weeks instead of building from scratch, customized to their brand voice and assortment.
