What Is AI Readiness?
AI readiness measures how easily large language models (LLMs) like ChatGPT, Gemini, Claude, and Perplexity can crawl, understand, and recommend your website.
Unlike traditional SEO which focuses on Google rankings through backlinks and domain authority, AI readiness focuses on structured signals that help machines parse what you do and who you serve. When a buyer asks ChatGPT "what's the best tool for X?", the model reads these signals to decide whether to name your product or a competitor's.
The good news? Unlike backlinks (which take months to build), all 8 AI-readiness signals are fixable in an afternoon. They're files and tags, not authority metrics.
The 8 Signals AI Crawlers Look For
1llms.txt
A markdown file at your root domain that tells LLMs what your product does, who it's for, and how it works. Think of it as a README specifically for AI models.
How to fix: Create a llms.txt file with your product name, description, key features, pricing URL, and documentation links.
2llms-full.txt
An expanded version of llms.txt with more detail about integrations, use cases, and technical specifications.
How to fix: Extend your llms.txt with FAQ sections, integration lists, and comparison data.
3Schema.org JSON-LD
Structured data markup that tells machines exactly what type of entity you are (SoftwareApplication, Organization, etc.) with machine-readable properties.
How to fix: Add JSON-LD script tags to your pages with proper schema.org vocabulary.
4sitemap.xml
Helps crawlers discover all pages on your site. Without it, LLMs may miss important content.
How to fix: Generate a sitemap.xml at your root domain listing all public pages.
5Meta Description
The summary LLMs lean on when describing your product in their answers. Empty or duplicate descriptions hurt comprehension.
How to fix: Write unique, descriptive meta descriptions for every important page.
6Open Graph Tags
Provide context when your links are shared and help AI systems understand page structure.
How to fix: Add og:title, og:description, og:image tags to all pages.
7Single Clear H1
LLMs use the H1 tag to determine what a page is about. Multiple H1s create confusion about your site's purpose.
How to fix: Audit every page and ensure exactly one descriptive H1.
8Canonical URL
Prevents duplicate content confusion when the same page is accessible via multiple URLs.
How to fix: Add canonical link tags pointing to the preferred version of each page.
