Hi guys,

Whatever we do, we aren't being able to find the source of CLS issue in our site. We are 0 sec CLS on mobile but stuck at 0.16 sec on desktop, that's why we are still failing on desktop. Can you help us here?

We have checked Cloudflare, google search console everywhere. There's nothing wrong.


Please help  

This group is our final masqurede. We have done everything possible.

Thanks again

Barry Pollard

When I type that page into PageSpeed Insight I don't get CLS data on that particular page and instead for the whole site:

Looking at that page and scrolling down, and reloading, I see a little CLS but not enough to explain that 0.17 overall.

However, the home page does have URL-level data:

And doing the same on that clearly shows a lot of CLS locally when I open the DevTools performance panel, scroll down, and reload:

When you're struggling to understand CLS you can use a Real User Monitoring (RUM) solution to collect the elements shifting from user which is usually the best way of understanding where the issue is. I understand Cloudflare includes this for free if you enable it though I'm not sure if they give CLS elements, but they will at least help pinpoint the individual pages for you.
