AEO Ultimate for Shopify

# Product schema and the storefront blocks

Product schema is structured data on each product page. It tells search engines and AI assistants exactly what you sell: the name, price, stock, brand, barcode and options. This guide covers what AEO Ultimate publishes, how to turn it on, and how to fill the gaps behind it. Watch the walkthrough, or read the guide below.

Product schema in the Shopify admin: what the AEO Merchant Listing block publishes, turning it on in the theme editor, and filling the gaps behind it.

## What does the AEO Merchant Listing block publish?

AEO Ultimate publishes product schema through a block in your theme called **AEO Merchant Listing**. A product with variants is published as a product group with every variant; a single item as one product. Each carries its offer with the live price and stock, the brand and a breadcrumb trail. Shipping and returns come from the block’s own settings in the theme editor, and are only published for products that ship.

Ratings appear only when a review app writes Shopify’s standard rating fields for a product. The app never makes them up, so a store with no reviews publishes no rating, which is the correct output.

## How do I turn the block on?

On **Start → Home**, under **Turn on the storefront blocks**, click **Enable in theme editor** next to AEO Merchant Listing. It opens Shopify’s theme editor in a new tab with the block already switched on. Press **Save**, and it is live on every product page. Nothing is written into your theme’s own code: the block goes out through Shopify’s theme app extension.

The Enable in theme editor link opens the theme editor with the AEO Merchant Listing block already switched on.

## How do I see what is published for a product?

**Start → Your results** shows the product knowledge the app stores for each product: the data the block turns into schema. Pick a product under **Show the code for** to see it, then use the **Google’s Rich Results Test** link to test the live page.

Your results: the product knowledge the block turns into schema, for any product you pick.

## Why is my product schema thin?

Schema is only as good as the product data behind it. **Catalog → Issues** lists the gaps product by product: no barcode (GTIN), which search engines use to match the same item across stores; thin descriptions; missing product types; and products not yet enriched. Each has a **Fix** button.

Catalog: the gaps that thin out your product schema, product by product.

## What does AI enrichment add?

Enrichment fills the rest. On the Mid plan and above, AI reads each product and extracts attributes like brand, material, colour and size, plus a Google product category, and stores them for the block to publish. It runs on your own AI key. Enrich products one at a time from the product list on **Home**, or all at once with **Bulk enrich** on Pro.

Enrich products one at a time from the list on Home.
