Very pleased to have helped out as an editor on the Cookies chapter of the 2025 Web Almanac, which had 70 contributors this year. Congratulations to everyone who worked on it, and a massive thanks to @tunetheweb.com who does so much behind the scenes to get it published.

Page weights look to be getting worse, due to image formats?...

GPTbot is an unpopular visitor then!

The new Web Almanac is out. 🎉 If you don't know the Web Almanac, it's pretty much a summary and analysis of the state of the web based on real data from the HTTP Archive. As a yearly tradition, I'll go over it and highlight/comment on the things that stand out. Let's go! 🧵

So glad I (finally) put myself forward for this. Such an epic project, I learned so much and got to work with some really great people. The rumour are true @tunetheweb.com is a legend

Whoop whoop! Almanac is out! Really enjoyed being an analyst this year for the page weight chapter, & am hugely impressed by what @not-a-robot.com & @barkseo.bsky.social wove with that data. 👏 to @montsecano.bsky.social for editorial chops & of @tunetheweb.com, who is a whole new plane of helpful!

The wait is over! The @httparchive.org has officially released the 2025 Web Almanac. 🚀 I led the new #GenerativeAI chapter, which "delves" ;) into the hard numbers of AI adoption on the web, backed by data from millions of sites. ➡️ almanac.httparchive.org/en/2025/gene... #theWebAlmanac #WebAI

Got something to share real soon...

My contribution to this years Web Performance Calendar is all about Third Parties and Single Points of Failure (SPOF). Based on @httparchive.org data I found that 67% of websites have at least 1 render blocking third party - and quite a few of them are SPOF risks!

New @httparchive.org analysis about sites adding AI Bots and Crawlers to their robots.txt files. While robots.txt doesn't "block" bots by itself, it's a clear demonstration of the preferences of site owners and the sentiment towards AI crawlers on today's web. paulcalvano.com/2025-08-21-a...

We're please to welcome Nurullah Demir as the newest maintainer of the HTTP Archive project! Nurullah has helped lead the Web Almanac over the last two years and we look forward to seeing what this year's edition comes up with! Welcome to the team Nurullah!
