What this means for your marketing in Seattle
Seattle is in King County and falls in IECC climate zone 4C. In a typical year NOAA's 1991-2020 normals show 4,376 heating degree days and 265 cooling degree days, so heating is the larger load.
For a spray foam or insulation contractor, that tends to move what homeowners search for toward cold rooms, drafts, high heating bills and ice dams. Pages, ads and Google Business Profile services built around attic insulation, rim joists, basements and crawl spaces usually match that intent better than a generic insulation page.
The "C" in 4C marks a marine climate, with mild temperatures and plenty of moisture, so air sealing and moisture control belong in the message alongside insulation.
Seattle had an estimated 784,777 residents on July 1, 2025 (U.S. Census Bureau). Google Maps rankings change from one part of a market to the next, so being visible near your shop does not mean being visible across the whole service area. The free Market Visibility Audit shows your ranking at a grid of points around your business.
How the Google Maps grid works in a market like Seattle
Google Maps does not show one ranking for a whole city. The result changes block by block, depending on where the searcher is standing. Our audit searches from a grid of points around your business and records where you appear at each one. Green means you are in the top 3 at that spot. Red means customers there are not finding you.
