How to Get AI SEO That Actually Delivers
Demand the AI-era receipts: citations won in AI answers, before-and-after AI visibility, and — still — the links question, because AI engines cite authoritative sources and authority remains earned. A London agency that can't show both layers is selling half a service at full-city rates.
The London Authority Premium
London's AI-search market has a quirk worth money: the city's businesses compete globally by default, which means the authority bar for AI citations is set by international competitors, not the shop next door. That makes link equity even more decisive here than in regional markets. The practical play: pair AI-era content work with genuinely earned authority — UK press, sector bodies, data-led pieces journalists cite. London firms that treat AI SEO as content-only stall at the citation layer; the ones that feed it authority inherit answers competitors can't buy their way into.
