AI Readability Guide
How AI agents read your website
Search is shifting from links to answers. ChatGPT, Claude, Perplexity and Google's AI summaries read pages directly and quote a few sources. Generative Engine Optimisation (GEO) is how you make sure your business is one of them.
Why AI visibility matters
Traditional SEO optimises for a ranked list of blue links. Agents don't show a list — they read a handful of pages and synthesise one answer. If an agent cannot parse your page, you are invisible at the exact moment a buyer is deciding. As agent traffic grows, this becomes the difference between being cited and being skipped.
The 11 signals we score
Your AI Readability Score is built from the signals agents rely on to understand a page.
Page title
The single clearest label an agent reads first.
Meta description
A concise summary agents quote when citing you.
Single clear H1
Tells the agent what the page is actually about.
Heading structure
Lets agents map sections and extract answers.
Readable text content
Without real text in the HTML, agents see an empty page.
Structured data (JSON-LD)
Schema.org markup turns content into entities agents trust.
Open Graph tags
Richer previews when agents surface your link.
Image alt text
The only way agents understand your images.
Declared language
Removes ambiguity about your content's language.
llms.txt
A dedicated file guiding agents to your key content.
AI bot access
robots.txt rules that allow or block GPTBot, ClaudeBot and others.
What is llms.txt?
llms.txt is a plain-text file at the root of your site (like robots.txt) that points AI agents to your most important content in a clean, readable form. It removes the noise of navigation, ads and scripts, so agents spend their limited context on what matters. Adding one is a quick win for your score.
How to improve your score
- Write a clear title and meta description for every page.
- Use one H1 and a logical heading structure.
- Put real text in the HTML, not only in images or scripts.
- Add Schema.org JSON-LD for your key entities.
- Publish an llms.txt and check your robots.txt allows AI bots.
