Top 5,000 domain adoption is still only 16.1% | Trakkr Research
An analysis of the top 5000 cited domains reveals that only 16.1 percent have adopted the llms.txt standard.
Methodology: Built from HTTP scans of 37,894 AI-cited domains, linked to 337,362 citations and 882 citation snapshots in the Trakkr corpus.
Claim
Among the top 5000 cited domains, llms.txt adoption stands at 16.1 percent.
Why it matters
Strategists should note that the highest performing cited sites are not yet clustering around a universal llms.txt playbook, indicating that early adoption remains a differentiator rather than a baseline requirement for visibility.
