What is llms.txt and does my business actually need one?

llms.txt is a plain text file placed at your website root that tells AI tools like ChatGPT, Perplexity, and Claude exactly what your business does and which pages matter most. Without it, AI tools guess — or ignore you entirely. SOCi's 2026 audit found ChatGPT recommends only 1.2% of local businesses. The file takes one afternoon to build and costs nothing.

How is llms.txt different from my sitemap or robots.txt?

robots.txt tells crawlers which pages to avoid. sitemap.xml lists every indexable page. llms.txt is different — it's a curated, plain-language guide written specifically for AI language models, not search engine bots. It tells the AI what your business does, who you serve, and which pages carry your most important content, before the AI has to guess.

How long does it take to create an llms.txt file for my business?

Most owner-operators complete it in under two hours. Use the free generator at llmstxt.firecrawl.dev — paste your URL and it auto-builds a starter file in under two minutes. Validate it at radarkit.ai, upload it to your site root, and you're live. Run the free Oscker AI Visibility Scan first at oscker.com to see your current baseline before you build.
