Though I shared a link from the @httparchive.org and the 2024 Web Almanac, sharing a chart from the the actual archive: over 5 yrs, the page weight has grown almost 30%, and there has never been an indication of slowing down. The almanac chapter covers much of the data proving so. 🧵⬇️

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).

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...

That marks the end of the 2024 Web Almanac. A little later than usual but worth it in the end.

And also means the ebook is now available:
