1. Define the Duncanville reporting boundary before reviewing ROI
Duncanville is recorded as a municipality in Dallas County, Texas. The 2020–2024 American Community Survey 5-year population estimate for Duncanville city is 39,683, with a margin of error of 60. That is geographic and population context, not proof of legal demand, search volume, competition, leads or revenue. For your firm, the practical decision is whether the dashboard should distinguish Duncanville city from broader Dallas County or other service areas. A city target, a county target and a metropolitan-area target should not be treated as interchangeable. Ask how each target is named, grouped and reviewed, and whether a partner can tell which geography a ranking, call or lead represents.
Recommended approach
Bring a written list of the locations and practice areas you actually want to evaluate. Confirm the geographic labels, inclusion rules and reporting periods before accepting any summary as a basis for budget or staffing decisions.
