FAQ
What is llms.txt?
llms.txt is a markdown file proposed by the llmstxt.org standard (Sep 2024) that sits at the root of your domain (example.com/llms.txt) and tells AI agents what your site is about, which pages are most important, and where to find clean markdown versions of your content. Think robots.txt for AI agents — but inverted: instead of restricting crawlers, it guides them.
Do major AI engines actually read llms.txt yet?
Adoption is partial as of 2026. Anthropic referenced the standard publicly; some retrieval-augmented systems (Firecrawl, smaller AI search startups) parse it; OpenAI and Google haven't formally committed. But shipping it costs nothing and positions you as forward-compatible — sites that ship llms.txt early benefit when adoption grows, and lose nothing if it doesn't.
What's the difference between llms.txt and llms-full.txt?
llms.txt is the index — page titles and one-line summaries with links. llms-full.txt is the full content of those pages concatenated into a single markdown file an LLM can ingest in one pass without crawling individual URLs. Ship both: the index for fast lookup, the full file for deep retrieval. Our generator produces both.
Where do I upload the generated llms.txt file?
The file must be served at the root of your domain — example.com/llms.txt. On WordPress, drop it into the root via FTP or use AIOSEO's llms.txt feature. On Webflow, Framer, and Squarespace, host the file via a static-file route or upload through the platform's custom-file feature. On a custom site, drop it next to your robots.txt.
How often should I regenerate llms.txt?
After every meaningful site change — adding new high-value pages, restructuring nav, retiring URLs, launching new product lines. For most sites, a quarterly refresh is enough. Doc sites and frequently-updated content hubs benefit from monthly regeneration to keep the index aligned with current content.
