1. Start with the site and the geography it serves
The U.S. Census Bureau records Glen Ellyn village as a municipality in DuPage County. Its 2020–2024 ACS five-year population estimate is 28,390, with a margin of error of 166. That fact identifies the place and county relationship; it does not establish legal demand, search volume, competition, leads or revenue. For hosting, its practical value is narrower: it helps you define the primary local scope of the website you are evaluating. Separate Glen Ellyn pages and DuPage County pages should not be treated as interchangeable hosting requirements. If your site includes multiple service or location pages, review whether the current infrastructure serves all of them consistently and whether the content remains accurate and relevant.
Recommended approach
Inventory the pages, forms, media, databases and domains that matter to the firm. Then decide whether your review covers only a Glen Ellyn-focused site or a broader Illinois service area. Keep that geographic decision separate from the hosting decision itself.
