Mini pumpkin time!

Josh @farrant.me's site has a lovely theme-switcher... that plays music! farrant.me

This is a neat feature, and excellent for a quick overview. It's also handy to point folks who are a bit less savvy with the performance report, or have less time / interest in the nitty gritty and want some more high level overview stuff. developers.google.com/search/blog/...

An invaluable summary and resource!

I am sure this will be hugely unpopular with a lot of people; but I think AI prompt visibility tracking is generally a big and expensive waste of time. 🤷‍♂️

All I want for my birthday is to hit 2K signups for my salty rants. I promise to bring receipts 🎂🥺 moz.com/webinars/dar...

data-nosnippet gets Bing support. Interesting suggested use cases in that announcement post

Largest Contentful Paint (from Core Web Vitals) is now available in Safari Technology Preview. webkit.org/blog/17504/r...

Oh good, the spammers have found sharing Google sheets as a way to sell their shitty links again. Sigh

The pull signs, and total lack of handles lead me to believe this is an area only accessible to those with sticky hands. I think I have found the secret Spiderman society HQ

It would have been rude not to, after all. What's the saying? "when in Rome, be in Dublin and have a pint of Guinness." Something like that anyway.

My startup GoonPass™ which uses your device's camera to not only determine your age but how horny you are, thereby directing you to the appropriate level of smut, will be secure, because everyone will be too sweaty to recognise IRL.

I mentioned before that we’re switching Lighthouse Performance audits to the new and improved Insights. The same Insights that you can see in DevTools Performance panel traces. That’s happening in Lighthouse 13 due to be released very soon. Maybe even this week!

Arrived in Dublin for the Google product experts summit, and what a glorious day it has laid on.

Never underestimate my ability to be snarky *and* right moz.com/webinars/dar...

i've jumped on the bandwagon and added my own animal-themed llms.txt variant lukealexdavis.co.uk/hippos.txt

In honour of the spooky season, I'm going to extend @markwilliamscook.com's standard and feed the LLMS bats.txt tamethebots.com/bats.txt Better than a fun-sized snickers.

Core Web Vitals mystery for ya: Why does Google Search Console same my LCP is bad, but every example URL has good LCP? I see developers asking: How can this happen? Is GSC wrong? (I'm willing to bet it is not!) What can you do about it? This is admittedly confusing so let's dive in... 🧵 1/12

Added a MCP Server for @not-a-robot.com and my robots.txt testing tool. Get the details here: tamethebots.com/tools/robots...

SVGOMG has been updated to use SVGO 4! (thanks Adrien Crivelli!) This is the URL for SVGOMG. Unfortunately someone maintains a fork with ads, so, err, don't use that 😀 jakearchibald.github.io/svgomg/

This is cool and been waiting for No-Vary-Search to escape Speculation Rules (where this was originally started) to the more general use case. This allows you to say that certain client-side URL params (e.g. gclid or other analytic params) can be ignored and still use the resource from the cache.

This was truly excellent, and you can still go catch up on YouTube (with plenty of other talks) and it's never too late to send donations!

Nice. MCP server for devtools. developer.chrome.com/blog/chrome-...
