How to Improve Site Speed Using LiteSpeed Cache, QUIC, & HTTP3

Ever since Google rolled out a Mobile First index, which officially take effect in July 2018, it has become necessity to maintain and improve site speed at all cost. Many sites has even lost their place on the search engine.

Let’s be frank, aside improving site speed, there are still other factors that boost a site that also needs concentration. The truth remains that all the SEO requirements is almost impossible to meet; when you improve one part you see another part lacking.

The more contents are added the more you notice what to improve on your site

On this page we have discussed about how to improve Site Speed because Google has made it a ranking factor.

Good news if you’re using WordPress, you have the opportunity of implementing applications called “Plugins” to help improve your site. That is the beauty of WordPress, someone will agree! And the Plugin used is called “LiteSpeed Cache” plugin. With the help of the plugin and we were able to improve site speed.
