Real user data is great. Actionable real user data is better! Great post from @tkadlec showing how to make more meaningful, intuitive attributions for your RUM metrics (including Core Web Vitals) – making it easier for you to home in on #webperf issues. speedcurve.com/blog/providin…

The takeaway: Don't just look at the numbers for your performance metrics. Visually validate them to make sure they're measuring the right things! #webperf #ux #sitespeed #pagespeed #corewebvitals
So great to see how many media sites in our Page Speed Benchmarks have sub-2.5s LCP times! For some sites with poorer LCP, perceived #webperf/#ux isn't the issue. They're fast to start render. The main culprit is that the LCP element is just wrong. app.speedcurve.com/benchmark…

Is INP any better than FID?
28 Nov 2023
Now that INP has arrived to dethrone FID as the #CoreWebVitals responsiveness metric, it's time to scrutinize its effectiveness. @cliffcrocker looks at real-world data and asks: What correlation does INP have with #UX and business metrics? speedcurve.com/blog/INP-user… #webperf
