Start with the geography you are willing to serve
Google Local Services Ads use service areas and proximity as part of the placement decision. For a firm serving Pleasanton, the first question is not how many people live in the city. The useful question is whether the firm wants inquiries from Pleasanton city, from elsewhere in Alameda County, or from a narrower area tied to its practice and capacity. Pleasanton is recorded as a municipality in Alameda County. That relationship can inform the boundaries you review, but it does not justify assuming that the entire county is an appropriate target.
Recommended approach
Set the intended geography before discussing budget. Separate Pleasanton from any additional Alameda County communities you may serve, document excluded areas, and decide how the intake team will handle an inquiry outside the accepted service zone. Review geographic settings when capacity, office coverage or matter selection changes.
