I improved LCP with 250ms on 20K pages
The red paint chip (<div> with background #cb3539) was not picked as the hero element
Injecting large hidden text fixed the attribution
Do you have other suggestions?

Measuring LCP(FE), the front-end component of LCP Provides these
#WebPerf benefits
Visibility in what the front-end team influences
Smaller wins don't evaporate due to backend noise

Recently, I have been using https://www.webpagetest.org/ a lot while doing a performance analysis. I must admit that they are doing a really great job helping perf. engineers and developers with
#webperf. Keep up the good work and thanks@RealWebPageTest!

To fix CLS:
disable sticky header
get rid of extra margins
get rid of ads and other iframes from above-the-fold
add media width & height to hint browser for space allocation
preload fonts to avoid FOUT/FOIT
What else?

AB testing and

mobile inequality gap in one screenshot (Apple’s website):
iPhone 8, 4G: passes as fast for Core Web Vitals
MotoG4, 3G: fails or needs improvement
measuring on fast phones & network only is a sure way to misrepresent speed.
not everyone has a $2,000 phone

A
#webperf anti-pattern I see far too often is late loading hero images. If your Largest Contentful Paint is higher than expected, check that your hero images can be discovered early (i.e. are src's in your HTML!) to avoid issues like this. pic.twitter.com/F92Bnoh7vG

This is good news!
As anyone who has followed me for a while, you know I've been against AMP since its inception.
I'm all for speeding up the web, but there are much better ways to do it. Creating a separate ecosystem is not the answer.
