Linking and the companion file
The home page of canonical.com links the file in its HTML. Ora's lab found (2026-10-19) that 86 percent of llms.txt fetches by agents arrived through a link, so an unlinked file is mostly a file nobody opens. An llms-full.txt is served at the same root.
How it compares
At 26 KB the file is larger than 83 percent of the 2,529 plain-text llms.txt files in this edition, and its 138 links put it ahead of 85 percent of them on link count. The home page declares no generator. Size bucket: 10 to 50 KB. Tranco rank 2,489. Category: Top 10,000, no category.
