NeverRanked Position on llms.txt

The llms.txt standard, proposed at llmstxt.org by Jeremy Howard, is the cleanest answer to a real problem: AI engines need a curated, machine-readable map of a site’s most citable content, separate from what crawlers index for human users.

NeverRanked treats llms.txt as a first-class deployment artifact alongside Schema.org JSON-LD. Both layers feed the same goal: make a site reliably citable.

The standard, in one paragraph

A markdown file at /llms.txt (root). Begins with an H1 that names the site. Followed by a blockquote that summarizes what the site does in one or two sentences. Then optional H2 sections (typically ## Docs, ## Examples, ## API, ## Optional), each listing curated links in the form - [Title](url): one-line description. A companion /llms-full.txt may concatenate the full content of all linked pages for direct AI ingestion.

What good looks like

The minimum viable llms.txt is a half-dozen well-chosen links. The maximum is a curated information architecture.

Engine adoption status, May 2026

Engine Respects llms.txt? Notes
Anthropic / Claude Yes Anthropic proposed the standard; Claude reads it preferentially
OpenAI / ChatGPT Stated intent Public statements indicate respect; behavior inconsistent in scans
Perplexity Inconsistent Sometimes follows the curated set, sometimes ignores
Google AI Overviews No Currently uses standard search index
Microsoft Copilot No Currently uses Bing index
Gemini No Currently uses Google Search index

This table changes month to month. NeverRanked’s engine changelog (content/engine-changelog/) tracks shifts as they happen.

Why this matters for AEO score

Sites that publish a curated llms.txt give the engines that respect it a deterministic citation surface. Engines that respect llms.txt will weight content listed there above content discovered via crawl. Sites without llms.txt get crawled indiscriminately, with all the noise that implies.

The compounding effect: once one major engine starts treating llms.txt as a strong signal, the others follow. We expect this to happen in the second half of 2026. Sites with llms.txt deployed by that point inherit the advantage. Sites without lose two-to-three months of citation share to faster movers.

NeverRanked’s deployment path

For each customer:

  1. Audit current llms.txt (present, absent, valid, stale)
  2. Generate vertical-aware template (banking, real estate, legal, healthcare, hospitality, education)
  3. Customize with the customer’s actual canonical pages
  4. Deploy via the same snippet that handles schema injection
  5. Track weekly: which engines respect it, what gets cited from it
  6. Update quarterly as the customer’s content evolves

The NeverRanked snippet handles llms.txt the same way it handles JSON-LD: a curated, validated layer that updates as the site does.

Public commitment

NeverRanked publishes its own llms.txt at neverranked.com/llms.txt as the reference implementation. Anyone can verify our position is not aspirational by reading what we ship for ourselves.
