Before moving further down this section, I recommend testing the page speed of your website, to know, where your website stands now.

Once you implement the changes mentioned in this section, you will move to <1s page loading time.

Eg. case: If you website is taking 5 sec to load now, then you will get 400% to 500% page speed improvement.
