Each field the store's products leave out, the most products first. One change to the store's product template fixes every product at once.

Some product pages send no Product data before any script runs, so a shopping agent has nothing to read. Write it into the product template.

A count of fields says what a page's data states, read before any script runs. It does not decide eligibility: Merchant Center and Google's own review decide whether a product shows in merchant listings, Universal Cart or any other Google feature.

The whole site88 of 100

Every page of stoneandpestle.com against mttr's rulebook: 55 pages read.

See the full report

Fix it where the data starts

The Shop Ready skill works in your store's own theme with Claude Code, Codex or Cursor, writes every field from the product's own data, and checks the live pages with mttr after. On Shopify, mttr can do it from the admin: that is in beta.

Get the skill mttr for Shopify

Agentic SEO, GEO and AI citation optimization. mttr reads your site the way search engines and assistants do, hands the fixes to your agent, and checks each one on the live site.
