Hi, Im Having a CLS trouble on my mobile site.
When I checked my site on google Dev tools, it looks like a Featured Image dissapears and comes back.probably this is the issue, well actually I have no idea.
Lab data is fine but Field data is the issue.
would you have a look at my site please?
Hi there,
I've checked the site and it seems to be using an optimization plugin.
One of the most common cause of CLS we see among users is Optimized CSS Delivery (Critical CSS).
Can you try disabling the Optimized CSS Delivery (Critical CSS) and see if it improves?
Let us know.
Thanks for your reply.
I use Wp-rockwt and I do Minify CSS files and Combine CSS files, but I dont use Optimize CSS delivery.
Should I stop using Minify CSS files and Combine CSS files ?
Hi there,
I tested a couple of posts/pages in google PSI but i am not seeing any Field Data - only Origin and Lab.
Lab is good, Origin fails. But Origin is an aggregated value of all pages tested on your site, it doesn 't identify which URLS have the issue - does you Google Search Console display which URLs are failing ?
Yeah Lab date is fine, mostly CLS is 0 or like 0.001, but Field date which is the user date fails.
Search console says all the pages fail.
Lab Data only checks initial load, whereas Field Data will collect CLS issues that occur after load - which means something loading later on in the site is causing the issue.
I checked the site using the developers peformance tools on Mobile / Throttled 3g network and the the CLS is being generated by the Drop Down sticky advert you have at the top of the page.
You will need to address that issue with whomever is providing that function.
Drop Down sticky advert?
is it about ads like Adsense ? or Humberger menu?
I mean this advert:
Oh Adsense... Ok thank you so much. Ill stop using that.
You're welcome
