Your /llms.txt
# Acme Analytics > Acme Analytics is a privacy-first web analytics tool for Next.js and Astro sites, self-hosted or cloud. Pricing is per site, not per seat. The docs below are current for v3. ## Docs - [Quickstart](https://acme.example/docs/quickstart): Add the script and see your first visit in 5 minutes - [API reference](https://acme.example/docs/api): Every endpoint, with curl examples ## Blog - [Cookieless analytics in Next.js](https://acme.example/blog/cookieless-analytics-nextjs) ## Optional - [Changelog](https://acme.example/changelog)
What the spec asks for
In this order: an H1 with the site or project name (the only required part), a blockquote with a short summary, optional plain detail text with no headings, then H2 sections that each hold a Markdown list of - [name](url): notes links. A section named Optional marks links an agent may skip when it needs a shorter context. See this site's own /llms.txt for a live example.
Where to put llms.txt in your stack
- Next.js:
public/llms.txt, or a route handler at app/llms.txt/route.ts that builds it from your posts - Astro:
public/llms.txt, or an endpoint at src/pages/llms.txt.ts - Hugo:
static/llms.txt - Jekyll:
llms.txt in the site root (files without front matter are copied as-is) - Gatsby:
static/llms.txt - Docusaurus:
static/llms.txt
A static file goes stale the day you publish a new post. To generate it from your Markdown on every build, follow the llms.txt guide for developer blogs, and to give AI answers something worth citing, see how to get a developer blog cited in AI answers.

FAQ
What is llms.txt?
A Markdown file served at /llms.txt that tells AI agents and LLM-based tools what your site is and which pages matter most. It is a proposal published at llmstxt.org, not a W3C or IETF standard.
Does llms.txt improve Google rankings?
No. It is not a Google ranking signal. It is a cheap, low-risk guide for AI tools and agents that choose to read it; regular SEO still depends on crawlable pages, links and useful content.
Is anything I type sent to a server?
No. The generator runs entirely in your browser; nothing you type or paste is uploaded or stored.
What goes in the Optional section?
Secondary links an agent can skip when it needs a shorter context, such as a changelog or older posts. Put your most important docs, guides and pricing in the sections above it.
Do I need llms-full.txt too?
No. llms-full.txt (the full text of your pages in one file) is a common extension, not part of the core spec. Start with llms.txt and add the full version only if your docs are what agents need verbatim.
Put your blog on autopilot
An llms.txt points AI agents at your best pages; Blogger Dog keeps adding them. It researches, writes and commits SEO/AEO posts to your GitHub or GitLab repo on a schedule. Your first 3 posts are free, then plans start at $19/month.
