llms.txt GeneratorAre canonical and Open Graph tags common on cited pages?
Yes. 91.4% of cited pages in the study have canonical tags and 89.2% include Open Graph tags.
The key numbers.
- Canonical tag rate
- Share of cited pages with a canonical tag.
- 91.4%
- OG tag rate
- Share of cited pages with Open Graph tags.
- 89.2%
Basic metadata hygiene is part of the default profile of a citeable page, indicating that proper technical foundations correlate with AI visibility.
The evidence.
| Measure | Result |
|---|---|
| Canonical tag rate Share of cited pages with a canonical tag. | 91.4% |
| OG tag rate Share of cited pages with Open Graph tags. | 89.2% |
Population and method
Built from 1,465 AI-cited pages across 950 domains, using 28,033 citation opportunities and page-level crawl analysis.
Where the evidence stops
Most findings are correlational. Overrepresented traits are not the same as proven causal lifts.
Some subgroups, especially FAQ Schema + FAQ Content, are relatively small and should be read carefully.
The study looks at cited pages rather than all uncited pages in the open web, so it is best used as a benchmark profile.
What to do with this
- Make answer pages denser, more structured, and more explicit about authorship and freshness.
- Use schema where it helps machine readability, but avoid treating markup as a substitute for strong content.
- Design pages to be extractable with concise answers, tables, lists, authors, and clearly marked evidence.
Operators must ensure standard metadata is present to remove technical friction for AI crawlers, making proper tagging a baseline requirement for content publication workflows.
