Metro Boston is a patchwork. Boston proper, Cambridge, Somerville, Brookline, and Quincy each have their own town or city hall, their own permit office, and their own search habits. A customer typing Somerville plumber and one typing Back Bay plumber are not shopping the same map.
The housing adds to it: brownstones and condo conversions in Back Bay and the South End, triple-deckers in Somerville and Dorchester, and suburban houses along Route 128 each produce different jobs and different words.
Zillow, MLS PIN, and Realtor.com already own the searches from people browsing listings, so an operator's pages need to target service, management, and maintenance terms instead. The seasons matter too. Frozen pipes and boiler failures spike in January, and turnover cleaning peaks around September 1.
We plan your pages around those swings, and nobody can promise a ranking.
