How Operators Buy AI SEO in London
Pilot on one service line: agree five money prompts, baseline who AI recommends, ninety days of work, re-measure. Keep your own logs. London's AI-SEO market is young enough that the pilot separates practitioners from decks faster than any reference call.
Operator Notes on the London Market
Field notes: London's AI-SEO talent concentrates in a handful of genuine practices — beneath them sits a long tail of rebadged retainers riding the trend. Reference-check by asking clients specifically about the AI layer ('what changed in AI answers?'), not general satisfaction. Watch for the enterprise-team trap: big-name agencies staff SME accounts with juniors while seniors serve the logos. And note the arbitrage: London capability at London prices versus equal capability delivered remotely — the M25 adds cost, not rankings.
