This question may have been asked before, in which case I apologise for my ignorance. But could you tell me what your definition is of a mobile webpage? I can understand it for sites built ca. 2000, but are people still building separate mobile versions?

We get a list of origins visited by mobile devices (based on user-agent) from the Chrome User Experience Report (CrUX). We then crawl them with mobile viewport, mobile user agent, and 4G setting as detailed in our methodology: almanac.httparchive.org/en/2024/meth...

So they may be the same as desktop pages, they may be responsive and deliver different content to mobiles (based on user-agent, or viewport size), or they may be mobile-optimized sites not visited by desktop devices (e.g. m.facebook.com).

Cool, thanks I understand. It would be interesting to see what share of pages actually produce different code (ie, do user-agent sniffing on the server).
