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.

Get a better host, I'm using googles VM & it's fantastic.

Code optimization , CDN usage and js,css minifying are the best solutions that works for me the most of time.

Check for repeat coding and remove it. Also remove or delete unnecessary lines of code.

You can use https://gtmetrix.com and https://tools.pingdom.com/ to analyze your website. it is better to use CDN too. make sure that your PHP version is php7+ and your CMS is up to date.

You can work on DNS leve and content leve. DNS = use a DNS cloud service ... content = use a CDN

you can clear the website cache or optimize the code yourself or ask the host to improve

try to decrease the number of plugins/app you have on your site.

It does bring a lot of features but each app or plugin can easily add half a second of loading time

my bros wordpress site is running on PHP 7.3. apparently it is always better to use upgrade version mpty recycle bin, clear cache

Use cloudflare to cache server resources
