How SEOglow ran the study
We selected seven businesses whose public sites listed Oak Brook or an Oak Brook address. We followed homepage redirects and parsed the returned HTML for heading tags, phone links, and an Oak Brook text mention. Five homepages returned usable HTML. Visser Heating & Air and K&J Heating and Cooling could not be retrieved by the script and were excluded from the counts.
This is a convenience sample. The checks describe returned homepage HTML at one point in time. A site may add content with JavaScript. The study does not measure rankings, lead volume, or all HVAC businesses in Chicagoland.
