Hi there,

you can use the Flying Scripts plugin to defer the loading of your advert scripts:

Thank you David i ll try. is there any solution for heading problem ?

What exactly is the issue ?
Is it you cannot save in the Block editor or the formatting you need from the classic editor ?
If its the latter can you provide a link to your site so i can see the issue.

i sent my login details and screenshot of problem. and most of my pages are looking in desktop like that.

if you can help me about decrease my CLS score on gtmetrix i ll be really glad its 0.8

Hi there,

The heading issue you're seeing is being caused by your images being floated.

You can try this:

.single .entry-content h3,
.single .entry-content h2 {
    clear: both;
}

When it comes to CLS/page speed scores, the best place to get tips is the tool you're using to test the site. They will give you a list of things to improve :)

Didnt work :(
Could you fix it for me ?

And i am getting lower score from page speed in youtube embed video pages. i am using wp youtube lyte plugin are there any other recommendation for this?

I'm not seeing my CSS on the page you linked to - did you keep it saved?

I don't have a ton of experience with YouTube videos, but the support for that plugin may have an idea.

Its working thank you.
Is there any solution for other errors of my page speed?

For you YouTube videos - you can try lazy loading them with this plugin:
