The four pillars

Scored against the published framework — fourteen signals, no model judgement anywhere in the scoring.

What the site probe found

The pages we sampled

Every one, openable. Each was taken from the middle of a different category listing — never a featured or promoted placement — so the sample reflects the catalog rather than its best shelf.

Page score is out of 69 — the portion of the framework scored per page. The remaining 31 points are site-level: consistency, gating, and the four agent-readiness signals.

What would move this number

Derived from the score itself, largest gap first — Product Data Depth lost the most points.

1. 1A GTIN or UPC appeared on 0% of the sampled pages. Identifiers are what let a marketplace, a search engine, or a procurement system recognise your listing as the same item everyone else is selling.
2. 2No schema.org Product markup was found in the server-rendered HTML. This is usually the cheapest fix on the list and it is the single clearest signal to a crawler or an AI agent that the page describes a product.
3. 3The richest and thinnest pages sampled differed by 24 attributes. A spread that wide usually points at categories onboarded under different rules rather than at any one bad page.
4. 4A price was published on 40% of sampled pages. Withholding price is a legitimate commercial strategy, and it is also a hard stop for any automated buyer comparing options.
