Amazon marketing · Answer
The short answer
A+ content is the enhanced product description area on an Amazon listing, built from image and text modules instead of plain HTML bullets. It is free to brand registered sellers and sits below the fold on the product page. Its job is to resolve the hesitation that stops a buyer, and most brands instead use it to tell a brand story nobody scrolled down for.
A+ content is the standard enhanced description available through Amazon Brand Registry, with a module library covering comparison charts, image and text blocks, and technical specification tables.
What people call B+ or Premium A+ is the upgraded tier, with larger modules, video, interactive comparison and hover hotspots. Availability and eligibility conditions for the premium tier change, so check what your account currently offers in Seller Central rather than trusting any article, this one included.
It is the only part of the listing where you control the layout rather than filling a field. That makes it the right place for the comparison chart that stops a buyer cross-shopping, the sizing guidance that prevents a return, and the specification a buyer will otherwise leave to find elsewhere.
Two of those pay twice. Anything that prevents a return improves both your conversion rate and the returns cost sitting inside your real break-even ACoS.
By writing a founder story. Somebody who has scrolled past the price, the images and the reviews is not looking for your origin, they are looking for the one thing that will let them press buy.
By using text baked into images with no alt text, which is unreadable to screen readers and to Amazon.
By designing it on a desktop. Modules stack differently on a phone, which is where most Indian buyers are, and a comparison chart that works at full width can be unreadable at 375 pixels.
