63.5%
63.5% of the 1,744 scored sites in Public companies fail the test of whether a canonical link names their real address (RCH-3). A further 449 refused the scanner and are not counted.
- Sites
- 1,108 of 1,744 scored sites
- Group

- 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

- How the census is run: methodology.
