1. Start with the geography you actually serve
Mount Vernon is recorded as a municipality in Jefferson County, Illinois. The 2020–2024 ACS five-year estimate records 14,090 residents, with a margin of error of 361. That describes the city and its population estimate; it does not establish legal demand, search activity, competition, inquiry volume or revenue. If your practice serves Mount Vernon as well as other parts of Jefferson County or Illinois, the attribution design should preserve those geographic distinctions instead of treating every inquiry as “local.”
Recommended approach
Before a consultation, write down the geographic labels your team already uses for matters. Ask whether an inquiry should be classified by the person’s location, the matter’s location, the page visited, or the office’s service area. Then decide which of those fields should be reviewed alongside channel and outcome data.
