AI Visibility Audit 2026: 15+ Resources, Methodology, Tools | AI Labs Audit

AI visibility audits precisely measure how a brand appears in answers produced by generative engines: ChatGPT, Claude, Gemini, Perplexity, Copilot, Mistral, Grok. An audit quantifies share of voice, sentiment, citations vs mentions, and surfaces the competitive prompts where your brand is missing.

A rigorous audit combines two dimensions: the native score (no web search, testing the LLM's memorised knowledge) and the web score (with browsing, testing the engine's ability to find and cite your site). The two tell different stories: a brand can be well indexed yet not memorised — or the other way around.

This hub centralises AI Labs Audit's audit methodology, hero grades (A+ to F), key metrics (share of voice, citation rate, sentiment), per-engine audits (ChatGPT, Claude, Gemini, Perplexity), premium PDF reports and scheduled audits for long-term tracking.
