llms.txt: The File That Decides Whether AI Can Find Your Site

Short summary

llms.txt is a new Markdown file (placed at site root) that tells AI crawlers what your site is about and which pages matter most—complementing robots.txt for access control and sitemap.xml for navigation. Major tech companies (Stripe, Cloudflare, Vercel, Anthropic) have already adopted it. While direct traffic impact is unproven, the cost-benefit ratio is compelling: 15 minutes to implement, zero downside, potential major value if AI search becomes the standard.
