llms.txt: what it is and why your site should have one

An llms.txt file is a short, plain-text guide that tells AI models who you are, what you offer, and which pages to trust. It sits at the root of your site, the way robots.txt does. Here is what goes in it and why it helps AI answer questions about you correctly.

What goes in an llms.txt

• A one-line description of who you are and what you do.
• Your main products or services, each with its canonical page.
• The key pages you want an AI to read first.
• Short notes that clear up anything an AI might get wrong about you.

It doesn't replace good content or schema. It's a signpost that makes it easier for an AI to describe you accurately, and harder for it to confuse you with someone else.

How an AI decides who to cite

An answer engine doesn't "rank" pages the way Google's ten blue links do. It retrieves a handful of sources, synthesises an answer, and credits the few it trusts most. What earns that trust is fairly consistent:

• A clear, direct answer the model can lift in one clean sentence — not buried three scrolls down.
• Structure it can extract — headings, lists, tables and schema that map to how a model chunks a page.
• Entity consistency — your name, category and claims matching everywhere the model looks, so it builds one confident picture of you.
• Corroboration — third-party mentions and citations that make the model comfortable repeating you.
• Freshness — current, dated material beats a stale page on the same topic.
• Crawl access — an llms.txt, sane robots rules and fast server-rendered HTML the AI crawlers can actually read.

Why run it as one agentic program

Most teams treat SEO, AEO and GEO as three separate chases. Edthi runs them as one: a single plan, built on the same anti-slop content engine behind our AI Marketing Agent, so the content reads like a person wrote it and is structured for a machine to cite. Everything is measured query by query against a baseline set on day one, and reported every week.
