Thanks for your reply,
I have provided my Credentials in the private section. So this is now making me crazy. Please have a look in my settings, As I mentioned that I am using Litespeed cache, please feel free if you think that you can make it better with other caching and minifying plugin.
Mobile score is really very bad around 25% which will completely destroy my SEO. As these day 90% users are visiting website on mobile phones that is why Mobile Score is very important.
These tests I have done on Google Page Speed Test.
Please help me in this case and I would be really very thankful.
