66.9%
66.9% of the 34,414 scored census entries across 16 cohorts in the United States fail the test of whether a canonical link names their real address (RCH-3). A further 8,173 refused the scanner and are not counted.
- Sites
- 23,021 of 34,414 scored sites
- Group
- United States, 16 cohorts pooled
- Distinct addresses
- 32,758 (a site on two rosters is two entries)
- Test
- RCH-3: Does each page say which web address is the real one?
- Edition
- Census Q4 2026, Index 12.1, computed 2026-11-06
- Caveat
- Public rosters, not a random sample of the web; a site on more than one roster counts once in each, and says nothing about sites outside the United States.
How to check
- The group and its sites: United States.
- How the census is run: methodology.
- The figures: summary.json or claims.json.
- Every published figure: all claims for the United States.
