1. Start with the service area you actually want to measure
Los Altos Hills is a municipality in Santa Clara County, California. Its 2020–2024 ACS five-year population estimate is 8,377, with a margin of error of 75. That is useful for naming the geographic scope of a measurement conversation. It is not evidence that residents are searching for a particular legal service or that a page, advertisement or referral will produce a client. Your attribution plan should therefore distinguish Los Altos Hills from the wider Santa Clara County area and from any other California communities you serve. Combining those places in one report can make a local channel look stronger or weaker than it is.
Recommended approach
Decide whether your reporting should show Los Altos Hills separately, group it with Santa Clara County, or compare both views. Record the geographic definition before judging a channel or landing page.
