For Core Web Vitals what is CLS measured in? Why is 0.1 considered not good and 0.25 bad, and what do those numbers represent?

I've had 3 separate conversations on this with various people in last 24 hours so figured it's time for another deep dive thread to explain...

Bon matin, @_welovespeed! I’m so excited to be here to talk about how #webperf is not just good for your business — it’s good for your brain. I’m also happy to be representing Team @SpeedCurve. If you want to talk about performance and UX, please come and say hi!

This is a BIG change to Chrome DevTools Perf Panel to make it easier to see and reproduce issues BEFORE doing a full trace.

So you can be more confident you’re tracing the right thing.

It really has been only 4 years - and CWV became a staple of the conversation and a great start for people's journey to understand Speed of User Experience! Thank you, Google Team for keeping it up!

[Barry Pollard @tunetheweb]

Was asked by someone* at work today to confirm that the Core Web Vitals REALLY was only 4 years old as seems like much longer.

It's amazing how much they've become part of our shared vocabulary in such a short space of time!!

* Name spared to protect the guilty 😉
