The 60-Second London Vendor Test
One question sorts London's field: 'name a client cited in AI answers because of your work, and show the before-and-after.' Specifics win; 'AI-powered processes' loses. Then confirm the team doing the work includes actual SEO practitioners.
What London AI-SEO Receipts Look Like
The receipt hierarchy for this market: screenshots of AI answers citing client sites (dated, prompt shown) beat everything. Then published AI-search research — Croud's AI Overview studies are the reference standard. Then named case work with method described. Awards and 'featured in' walls rank last; London mints those weekly. When two agencies pitch similar capability, ask both for the same artefact — an AI answer their work changed — and watch one produce it in minutes while the other schedules a follow-up call. That's the whole decision.
