About AI Visibility

What is AI Visibility?

AI visibility refers to your website's ability to be accessed, parsed, and referenced by AI search engines and Large Language Models (LLMs) like ChatGPT, Claude, and Perplexity.

Why Speed Matters for AI

Unlike traditional SEO where slow sites rank lower, AI systems face a timeout wall (1-2 seconds) where slow sites are treated as unavailable. After that, race conditions determine ranking — AI systems query multiple sources simultaneously and only process the fastest responses.

Key Concepts

GEO (Generative Engine Optimization)

The practice of optimizing content and performance for AI-powered search engines and answer engines.

RAG (Retrieval-Augmented Generation)

Systems that query multiple sources in real-time to generate answers. Speed is binary - fast sites get included, slow sites timeout.

Timeout Wall

Most RAG systems timeout between 1-5 seconds. Sites exceeding this threshold are treated as unavailable.

Data Source

This tool uses the Chrome UX Report (CrUX), which contains real user measurement data from millions of websites. Metrics are calculated from the 75th percentile (p75) of actual user experiences.
