1. Start with the geography your firm actually serves
The U.S. Census Bureau records El Sobrante as a census-designated place in Contra Costa County, California. Its 2020–2024 ACS five-year population estimate is 16,294, with a margin of error of 1,702. That figure describes the population of the CDP; it does not establish legal demand, search volume, competition, lead volume or revenue. For attribution, the practical issue is scope. A report should distinguish inquiries associated with El Sobrante from inquiries associated with the rest of Contra Costa County or other service areas. Otherwise, a firm may treat a broad county result as evidence about one community.
Recommended approach
Before reviewing performance, define the geographic labels your firm wants to use for reporting. Decide whether El Sobrante is a distinct service-area label, part of a wider Contra Costa County view, or both. Then ask whether each inquiry record contains enough information to apply those labels without confusing a visitor’s location with the page or channel that generated the inquiry.
