Cumulative Layout Shift
Posted by on May 31, 2020 at 5:29 pmGoogle search console says my site has over .25. Agg. CLS is .35.
​
No idea what this means. I’m a layman. Is this simple to fix without coding? Is there a shopify app that can solve this? Super frustrated with this error message and lack of clarity.
​
Thanks
Ryan

It’s basically scoring how content “shifts” or adjusts after resources are loaded think of a space where a video player would be, later expanding the page after it loads and shifting content down/left/right.
It’s not necessarily an error, but you should try recording tests through webpagetest.org and see what content is shifting, or if it’s a false positive. Sometimes fonts loading can trigger CLS even though it’s just re-rendering.
