# Method

Each company's homepage was loaded in a rendering browser in September and October 2026, and the HTML, script URLs and cookies were matched against Installmap's fingerprint rules with `scrapers/detect.py`. A plain fetch is used for the few domains without a usable rendered record.

WordPress counts when the page loads assets from `/wp-content/themes/`, `/wp-content/plugins/` or `/wp-includes/js/`, links to `/wp-content/uploads/` or `/wp-json/`, or carries a WordPress generator tag. Elementor, Divi, Beaver Builder and Avada are WordPress page builders; every site where one was detected also matched WordPress. Other CMS are matched by their own rules.

The base for each list is the domains that returned a page. A company that runs WordPress only as a headless back end, with a front end that loads none of the paths above, is not counted. Neither is a WordPress blog on a separate subdomain.
