How to Make Your Website Readable for LLMs
Making your website LLM-readable ensures AI systems can find, understand, and cite your content. This guide covers the key steps from enabling AI crawler access to implementing structured data and semantic HTML.
Step 1: Enable AI Crawler Access
First, check if AI crawlers are blocked. Review your robots.txt file to ensure GPTBot, ClaudeBot, and Google-Extended are allowed. Remove any noai robots meta tags.
Step 2: Ensure Server-Side Rendering
AI crawlers typically do not execute JavaScript. If your site uses a JavaScript framework, implement SSR or static site generation. Glippy's machine readability checker detects whether your content is available in the initial HTML response.
Step 3: Add Structured Data
Implement JSON-LD structured data with appropriate Schema.org types. At minimum, add Article/BlogPosting for content pages, Organization for your homepage, and FAQPage for FAQ content.
Step 4: Use Semantic HTML
Structure your content with proper semantic HTML: meaningful headings (H1-H6), landmark elements (main, nav, article), and descriptive link text.
Step 5: Optimize for Citability
Format content so AI can extract answers: use FAQ sections, clear definitions, data tables, and quotable lead paragraphs. Glippy's citability checker scores how well your content is formatted for AI citation.
Step 6: Create an llms.txt File
Add an llms.txt file to provide a machine-friendly summary of your site's content and purpose.
