Red Flags in the London AI-SEO Market
Skip agencies whose AI offer appeared last quarter with no published work, anyone guaranteeing AI citations (nobody controls the models), and 'proprietary AI platforms' that are prompt templates. The nine above pass; hold newcomers to the same sweep.
A Five-Minute London AI-Visibility Audit
Logged out: ask an AI assistant your top three money questions with 'London' attached. Note who's cited — are you anywhere? Then the classic layer: search your main service plus London, note your position. Check your Business Profile completeness and review count against whoever the AI named. Those five minutes tell you your starting line on both layers, and they're the exact baseline to hold any agency against in ninety days. Repeat monthly; the trend is your real report.
