1. Define the geography before you judge performance
Chantilly is recorded by the U.S. Census Bureau as a census-designated place in Virginia, with a 2020–2024 ACS five-year population estimate of 24,036 and a margin of error of 1,426. The recorded county relationship is Fairfax County. That fact establishes a geographic frame; it does not establish legal demand, search volume, competition, leads, matters or revenue. Your dashboard review should therefore distinguish Chantilly from Fairfax County, the Washington metropolitan area, Virginia and any other service territory your firm chooses to track. A city label alone is not enough. Ask how a location is defined in each report and whether a city, county or statewide view can be separated. Also ask whether a “city” result refers to the searcher’s location, the page being promoted or another attribution rule.
Recommended approach
Write down the exact geographic views your partners use before the consultation. A reasonable acceptance criterion is that the firm can tell which location dimension a displayed result represents and can avoid treating the Chantilly population estimate as a forecast of case activity.
