Growing CLS on desktop

Hi there,

ran some performance tests and none of the posts i tested showed any CLS.
If the data is being reported in the Search Console, from real user data then it must be being generated by the end users device.

This is ONLY a theory but the issue could be related to Advert Blocker extensions on a users browser. As those strip the advert after the browser has reserved space for it. Which if true could be the problem. And if true the only way to resolve that would be placing the advert inside another container that has a min-height attached to it. I believe the Ad Inserter plugin has that option.

Hi David, thank you very much. The Advertisement is inserted in a separate container by AdInserter, so that can't be the problem. The data is from page speed insights 28-days User Report...

Thank you very much for investigating it.

Greetings Kathrin

Check with AdInserter to make sure - they may have more info on setting a minimum height just in case the AdBlockers are a problem.

Hi David

ran some performance tests

Please name them....

Hi Anil,

performance tests can be run in the Chrome Developers tools ( Right Click and Inspect the site ). Go to the performance tab, where you can throttle the network and CPU power. And there it provides options to reload and record the page load or can be just be set to record as you scroll through the site. In this instance those tests were purely to determine any potential CLS issues.

Thanks David, it will help...
Regards.

You're welcome

Hello, me again. The CLS is growing now more and more but just on desktop devices. I couldn't find any problem with AdInserter. But it must be something below the fold, because Page Speed and other tools can't measure it. I think the problem are the pictures...

The only CLS I can find comes from the Pinterest Browser Button that I have installed locally on my desktop device. Everytime the pinterest button appears it is captured as CLS that gets higher and higher when moving with the mouse over it. It is a hover button.

Greetings Kathrin

Really difficult to diagnose these kinds of issues. If you're seeing CLS being generated from a browser extension and my 'theory' that AdBlockers may also introduce a problem, there isn't much that can be done to eliminate those problems.

Might be worth asking on the Google Webmasters forum:

They may have some idea on what could be the issue or other ways to analyse who or what is generating them.
