Key Takeaways & Architectural Rules

  • Generate and validate a standard `/llms.txt` and `/llms-full.txt` file for your website in 1 click.
  • Verify robots.txt access rules for AI crawlers: GPTBot, PerplexityBot, ClaudeBot, and Google-Extended.
  • Audit your site's Schema.org entity graph (Organization, Product, WebSite, FAQPage) for semantic completeness.
  • Eliminate heavy JavaScript barriers that prevent fast AI model context ingestion.

EXECUTION PLAYBOOK

How to Do & From Where to Do (4 Steps)

01

Run an LLM Technical Readiness Scan

Screen: Left Sidebar → 'AI Search' → Click 'Readiness Audit' tab → Click 'Scan Now'.

SEO Runway checks your domain for `/llms.txt`, validates robots.txt directives for major AI crawlers, and parses your homepage JSON-LD markup.

Pro-Tip The audit score (0-100) indicates your technical accessibility to AI web crawlers.
02

Generate a Standardized llms.txt File

Screen: Readiness Dashboard → Click 'Generate llms.txt'.

Our tool automatically summarizes your core products, services, documentation links, and key pricing into clean Markdown conforming to the `/llms.txt` standard. Click 'Copy to Clipboard' or 'Download File'.

Pro-Tip Upload this file to the root of your web server (e.g. `https://yourdomain.com/llms.txt`).
03

Verify AI Bot Crawl Permissions

Screen: Crawler Access Card → Inspect 'Bot Permissions'.

Verify that your `robots.txt` does not accidentally block `User-agent: GPTBot` or `User-agent: PerplexityBot` if your goal is to maximize generative search visibility.

Pro-Tip Blocking GPTBot prevents ChatGPT from synthesizing up-to-date answers about your product.
04

Validate Schema.org Entity Connections

Screen: Schema Entity Graph Card → Review Entity Graph Nodes.

Verify that your `Organization` schema includes `sameAs` links to your official Wikipedia, LinkedIn, Twitter/X, and Crunchbase profiles to solidify entity recognition.

Pro-Tip Complete entity graphs provide search algorithms with unambiguous disambiguation data.

Field Insights & Advanced Tactics

Keep your `/llms.txt` concise and factual. LLMs have limited context windows; highlight only primary value propositions and documentation links.
Use clear Markdown headings (`#`, `##`) inside content sections to make extraction straightforward for AI scrapers.

Frequently Asked Questions

What is an llms.txt file?

An `/llms.txt` file is an emerging web standard (similar to `robots.txt`) that provides large language models with a clean, concise, markdown-formatted map of your website's key content without HTML clutter.
