Case Study: What Happened After a Site Added llms.txt
llms.txt is the 'table of contents' for AI engines. It doesn't directly boost rankings, but it helps AI understand your site faster and more accurately.
Why it matters
AI crawlers reading HTML get distracted by navigation, ads, and JS. llms.txt provides a clean Markdown index, making crawl efficiency dramatically different.
How to do it
Place llms.txt at your site root with a one-sentence description + 10 most important pages + key concepts. Pair with robots.txt allowing AI crawlers.
Visible changes
Within 2-4 weeks of deployment, AI engines' understanding accuracy improves noticeably, and citation probability follows.
Key Takeaway
llms.txt + robots.txt AI crawler access = your site goes from 'invisible' to 'understandable entity' in AI's eyes.
