2 product pages read, 2 with Product data, stating 5.5 of the 12 fields a cart reads on average. Read October 23, 2026.
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.
State stock as a schema.org value, such as https://schema.org/InStock, for each variant.
Name the brand, so the product can be matched across stores.
Give each product its barcode (GTIN), or at least its SKU, from the product itself.
Say each product is new, or how it is used or refurbished.
State what delivery costs, where it goes and how long it takes, once for the store or on each offer.
State the return policy: the window, the countries and who pays, once for the store.
Give each product the description its page shows.
The fewest fields first. The price and stock on each listing are what its data states, not what the page shows.

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.
Every page of customconstructionservicesmn.com against mttr's rulebook: 100 pages read.
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.
