Method
- Sample: ARC's curated directory, Index stores and accepted submissions (the same host set as the adoption tracker, Protocol Matrix and dataset). It is not all of e-commerce; read rates as describing this sample.
- Each store is counted once, from its latest completed plain-HTTP check (policies and product data from its latest attempt). Every metric has its own measured denominator (n); unavailable, blocked and legacy rows are excluded, never counted as 'no'.
- Groups with fewer than 10 checked stores show counts but no percentage.
- Platform comes from homepage fingerprints (headers and HTML). Not detected includes headless and custom stores. Stores whose homepage was blocked, or checked before platform detection, are unmeasured for platform and left out of the platform table (the coverage line gives the count).
- Market is ARC's curated label: the storefront's country (country-code domain or country subdomain), otherwise where the brand is based. EU means the rest of Europe; the UK and Ireland are separate. Index stores outside the directory carry the same curated label; submitted stores use their country-code domain, else Not labelled.
- Policy findings come from the store's pages and structured data. Presence does not verify the policy terms. A stated return window is the number of days found in structured data or the policy page.
- WebMCP is measured only on checks after 18:00 UTC on 6 Oct 2026, when detection began.
- Pages are generated from live saved checks and refresh hourly. Each page shows its data-as-of time; cite it with that date, or cite an immutable dataset version from /data/versions.json for exact bytes.
