how to increase website speed

First of all make sure that your PHP version for wordpress website is php7+. It is very fast than php 5. Secondly install WP Rocket Plugin. It is paid but you will get cracked versions around. Lastly; use imagify plugin to compress your image files.

I used these three steps and my wordpress site now opens around 3 to 4 seconds while previously it used to open around 12 seconds. Remember a time interval beyond 3 seconds also contributes to greater numbers of bounce rates as well.
