When your fancy WordPress website has just been released, it takes a longer time for loading. This is one of the downsides of using an open source content management system. Because there are many third party plugins or the more features you added.
So what are you looking for when it comes time to optimize your WordPress website? What reasons making your website loaded slowly?
There are 4 simple reasons why your WordPress site is probably running slower than it should be.
1> You have used too many plugins
The more plugins you use, the more resources your website needs. Before installing plugins on your website, you need to ask yourself for one simple question “Is this plugin really necessary for my website?” There are the great number of plugins which you really do not need to use. Let’s disable all unused plugins to save the resources.

2> Do not turn on cached for the website.
If you have not used a caching plugin yet, you should use it now. Page caching runs the PHP code only once every so often and stores the resulting HTML on the hard disk. When to entering one page, it automatically gets in the caching to load faster and faster.
There are a lot of plugins available for WordPress caching. Depending on your experience, choose the one you need. You can use W3 Total Cache for advanced clients and users, and WP Supper Cache for more basic caching needs.
3> Use of too many large images.
One WordPress website needs to use a lot of big images with the different sizes. Visitors and customers love it. It makes your website nicer and more eye-catching. But this is a reason leading to your slow website. Too many of images on a page can increase the loading time. Make sure that the page does not load too many images and these images should be in the correct size.
4> You have poor/ not too powerful host.
If you are using a shared host, it will limit your resources. Because there are hundreds of sites like yours all fightings for your resources on the same machine. And the host cannot solve if you run a complex WordPress Theme. You should check your hosting capacity and increase it if possible.
