Asked “What is [brand]?”, each platform gave an informed answer for 100% of the brands it was checked against. 100% of brands were recognised by every platform that answered. For well-known companies, being known by AI is not the gap — being recommended is.

When we built this benchmark, a large share of brands appeared to be invisible to one or more AI platforms. Almost every one of those misses traced back to how the check was run, not to the model:
We now exclude failed checks instead of counting them as misses, and match names with spacing and punctuation removed. If you track AI visibility yourself — with any tool — check how errors and name variants are handled before acting on a low score.

Brands. 303 established companies across 50 industries, chosen as representative examples of each sector, with a UK focus. Each has its own brand page.
AI recognition.Each week a batch of brands is sent the prompt “What is [brand]? Give me a brief overview: what they do, who they serve, and whether they are well-known or recommended in their space.” to ChatGPT (GPT-4o mini), Claude (Claude Haiku 4.5), Perplexity (Sonar). A brand is recognised when the answer names it and gives a substantive description rather than saying it has no information. Requests that fail are excluded, not scored as misses. This measures whether a model knows a brand, not whether it recommends it for category questions.
Technical SEO.Homepages are audited weekly with Surfaceable's on-page SEO, structured data and accessibility checks; the score is the average of the three.
Coverage. AI snapshots in this edition were taken between 26 October 2026 and 11 November 2026. The figures on this page recalculate automatically as new checks run.
