1. Define Columbia coverage before expanding it
The U.S. Census Bureau records Columbia as a census-designated place in Howard County, Maryland. Its 2020–2024 ACS five-year population estimate is 104,338, with a margin of error of 2,815. That figure describes the Columbia CDP only. It does not establish legal demand, competition, search volume, lead volume or revenue. For AI SEO, the useful question is narrower: does your website accurately explain whether you serve Columbia, Howard County, other Maryland communities or a wider metropolitan area?
Recommended approach
Start with a geographic inventory of the places your firm genuinely serves. Keep Columbia, Howard County and Maryland distinct in page titles, body copy, attorney details and structured information where appropriate. Review whether a prospective client can understand your service area without guessing. Do not create location pages merely because a place has a population figure; create or improve a page when it represents a real service relationship and adds useful information.
