This page collects data on how UK businesses appear — or do not appear — in AI-powered search platforms like ChatGPT, Google Gemini, Perplexity and Claude. It combines proprietary research from Rank4AI's audit of hundreds of UK SME websites with curated third-party data from published sources. We update this page monthly as new data becomes available.

Our aim is to provide a factual, observational picture of where UK businesses stand on AI-readable signals. We report what we found. We do not claim that any individual signal guarantees improved AI visibility, and we note limitations throughout.

TL;DR

53% of UK SME websites do not clearly state what the business does in their main heading
44% have no Organisation schema
52% have FAQ content on their homepage but no FAQ schema
87% have no llms.txt file
Only 4% have Person schema
Law firms were the only industry to score zero across every AI visibility signal
