Judging Genuine AI-Search Capability
The genuine-capability test: ask to see their AI-visibility tracking for an existing client — which prompts, which engines, what moved. Real practitioners have dashboards and logs; rebadgers have a slide about 'the AI revolution'. London has both in quantity.
Where London's AI Answers Are Won
Run the test for any London service — 'best commercial property lawyer London', 'best HR software UK' — and study the citations. They skew toward sources with three things: authority, structure, and specificity. That third one is the opening. London's big brands publish generic content at scale; a mid-size firm publishing genuinely specific, data-backed answers wins citations far above its weight. The AI layer rewards information gain over domain size more than classic Google ever did — which makes right now the best moment mid-market London has had in a decade.
