About LCP issue

Hi there,

if you check the PSI report you will see an option to filter the Opportunities and Diagnostics. Select LCP.
The main two factors are:

Improve Initial Server Response Time - this is something you should check with your host.
Reduce Unused Javascript - the main ones are the Ad scripts being loaded. Try using the Flying Scripts or other optimization plugins to defer the loading of your 3rd Party scripts.

My featured images are big but those images are compressed to minimum size.
Does it cause lcp more? If cause then there any solution for it?

The image sizes are good - if they weren't then you would see the Properly Size Images or other Image opportunities in a Google PSI report.

You need to look at the other issues i mentioned. As those are the only ones that google raise as having a direct affect on the LCP timings.

Thing to note about loading JS on the page. Ever JS loaded creates a task for the browser ie. it has to compile and execute the code. These tasks become longer when there is large JS files, or lots of JS files - these get noted as Long Tasks. Whilst the browser is dealing with Long Tasks it can't do anything else, including rendering the LCP element.

K thanks

You're welcome
