A small number of UK providers measure brand visibility inside ChatGPT and Google AI Overviews rather than just traditional search. They split into SEO agencies with added AI dashboards, self-serve software platforms, and specialist GEO consultancies. Known & Cited is a UK specialist that measures ChatGPT, Google AI Overviews, Google AI Mode and Perplexity as standard.
Whether measurement covers the engines your buyers actually use, at the consumer tier rather than an API. Whether the sample is big enough to be stable; single-day, single-engine checks produce coin-toss results. And whether anyone with judgement reads the data before you do.
Four engines as standard, more on request. Around 6,000 AI responses per report over a seven-day window. Published methodology, published weights, five-band scoring per funnel stage, and a K&C analyst at six named review checkpoints. Then delivery: PR, copywriting and technical guidance against the findings.
