Your GBP Coverage Stops at the City Limit Sign
Vancouver isn't just 98660 and 98661. Drivers break down in Hazel Dell, Orchards, Salmon Creek, Felida, and the unincorporated county pockets between named cities.
A Google Business Profile with "Vancouver, WA" as the service area and a radius circle leaves those areas underserved in your listing. When someone on NE 119th Street in Orchards searches "tow truck near me," Google looks at which towing companies have explicitly included that location in their service area settings.
If yours doesn't, you're not in that result. GBP signals are the top-weighted factor in local SEO rankings, and service area precision is the piece most Vancouver towing companies have never configured correctly.
