1. Define the Tukwila service area before spending
The Census record identifies Tukwila city and its relationship to King County. It does not determine which locations your firm may serve or which locations Google may associate with a Local Services Ads profile. Those are separate decisions. Your firm may want inquiries from Tukwila only, from additional King County communities, or from a wider Washington service area, but the appropriate scope depends on licensure, practice area, court or hearing coverage, consultation capacity and the matters you accept. Bosseo’s public product description identifies category and geography targeting as part of LSA management. It also says budgets and targeting can be adjusted when capacity changes.
Recommended approach
Start with an explicit service-area review. List the places your firm is permitted and prepared to serve, then compare that list with the locations you want to test. Do not use Tukwila’s population as a proxy for demand. Decide how an out-of-area inquiry should be handled and how geographic fit will be recorded when a lead arrives.
