Census Q4 2026

1,000 organizations · 929 scanned · Index 11.0, in effect 2026-09-24 · generated 2026-09-25

Complete, with gaps

929 of 1,000 organizations returned a score.

The run is finished. The other 71 refused the scanner, timed out, or failed outright, and no further attempt is coming — so every share below is out of what was actually scanned, never out of the cohort size. That a site cannot be read at all is itself a result.

What gated means

Gated means a site failed AIR-1.1 or AIR-1.2 — it blocks AI crawlers outright, so nothing else about it can be reached. The score is capped rather than averaged away, because a site nothing can read is not partly ready.

Where the failures are

The tests almost nobody passes

The share is out of the sites each test actually applied to — a test that was N/A for a site isn't counted against it, and the count is shown so a share with a small denominator can't masquerade as a sector finding.

The data

Published in full, named

Every site row carries the SHA-256 of the result behind its score, recorded when the scan finished rather than computed now — so a number on this page traces to a file, and that file to a run.

sites.csv One row per organization: name, host, score, grade, how many URLs were read, the renormalized denominator, and the result hash. checks.csv One row per cohort and test: how many sites it applied to, and how many failed. summary.json Everything on these pages, including the band distributions and the N/A reasons the tables above summarize.
