Greenwich scored highest of the large samples we took, which is unsurprising given how much is spent on presentation here. The gap is that spend goes into design rather than machine-readability — beautiful sites that an AI assistant still cannot parse.
We audited 55 business websites in Greenwich as part of a study of 622 sites across Fairfield County and Westchester. The mean technical score here was 82.5 out of 100.
Accounting demand is the most predictable of any category we cover — it surges hard around filing deadlines and goes quiet between them — and it is heavily trust-led.
The practical consequence is that the deadline surge goes to whoever the search layer can identify at the moment it arrives. Structured data and a working enquiry path are what convert that surge; the rest of the year they cost nothing to have had in place.
None of the tools listed above fix this on their own. Structured data, a click-to-call link and a booking path that works after hours are site-level plumbing — roughly an hour of work once. Do that before layering software on top, because these tools amplify whatever conversion path already exists rather than creating one.

For considered purchases the honest answer is 60 to 90 days before lead patterns read clearly, because the buying cycle itself is measured in weeks. Visibility changes sooner than enquiry volume does.
Greenwich scored 82.5 across 55 sites, the strongest large sample we took. Competition on presentation is real here; competition on machine-readability is almost non-existent, and that is the gap worth attacking.
For research, drafting and follow-up, yes — and it is already widespread. For anything client-facing or advisory, it needs a human check before it goes out. The firms doing this well use it to remove administrative load, not judgement.
