Do you know excessive load time of your website can lower your traffic? Now, we all know what that means, don’t we? It means that you are losing money! If your site takes more than 5 seconds to load, most of the people won’t even bother to wait for the page to load, they will simply hit the back button and visit any other website.

If you don’t want that to happen with your site, you must ensure that your site loads as quickly as possible! Optimum load time of a website is about 4-5 seconds and you must take proper steps to optimize your site speed. This is where caching comes in..

What is Caching?

If you are wondering what is caching, here’s what it is.

“Caching means storing recently used data briefly so that the PHP scripts aren’t loaded again and again every time a visitor re-visit a frequent web page/site.”

Think of it in this way. If someone visits your site; images, content, Javascript and other files are sent to the browser of the user. So, instead of sending that data, again and again, a cache plugin creates a static version of your website and whenever a user revisits your site again, the static version of your site is served to that user. This whole procedure reduces a significant amount of load time as you’re the PHP scripts are not loaded again and again.

Excellent article Jahanzaib. Several WordPress folks speaks about WordPress cache plugins and I have been testing out several resources from a quite long time. Well optimizing to achieve 90 benchmark is what every professional developer aims to achieve. I know that W3 Total Cache has a very good reputation in the industry. Recently I came across with an other useful resource, Breeze Cache Plugin that I would personally recommend WordPress Community to give a try. Anyways thanks for sharing.
