A number you can argue with, because every check behind it is published.
The score answers one question: if an assistant reads this page right now, can it understand and quote the product. It is built from four dimensions, each made of named checks, and each check tells you what it looked for and what it found.
Analytics tell you nobody came. They do not tell you why.
A product page can rank perfectly for a human search and still be unusable to an agent: the price rendered by JavaScript, no identifier to match against, a description that never states the size. The score separates those failures from each other so you can fix the one that applies.
Grade bands: A 90 to 100 · B 75 to 89 · C 60 to 74 · D 45 to 59 · F below 45.
Four dimensions, one number, no black box.
Agent accessibility
Whether a crawler can reach the page and see the substance without executing your JavaScript: robots rules, response codes, server rendered price and availability, and the presence of an llms.txt.
Structured data
Product, Offer and identifier markup. Whether the GTIN, MPN or brand an assistant needs to match your product against a query is actually present and valid.
Content answerability
Whether the copy answers the questions a buyer asks before paying: fit, compatibility, materials, dimensions, what is in the box, warranty.
Multi-language parity
Field by field comparison between locales. A German page missing the specification table scores lower than the English page it was translated from.
Every registered product carries its own score and its first failing check.
The catalog number is an average you can open. Filtering to grade D and F with traffic gives you the 312 products worth starting on, each with the check that failed named in the row.
Scoring, rescoring and the full breakdown are free. The public check on your domain needs no account. The connected catalog score needs a store connection but no plan, and it stays visible if you cancel.
The score describes how readable and answerable your pages are for an assistant. It is not a ranking, not a prediction of sales, and not a promise that any assistant will recommend you. Estimated score movements next to a proposed fix are labelled EST.
