Keeping your WordPress website loading time as fast as possible is very important. When a person lands on your site for the first time, you only have a few seconds to capture their attention to convince them to hang around.
Here are a few easy steps to follow and some plugins to install to load your site a lot faster.
Go into your Installed Plugins and select Inactive. Scan through all plugins you do not need anymore and remove them and their files.
Reducing images one by one can be a very long and slow process and painfully slow.
Fortunately, there is a free plugin called WP-SmushIt which will do this process to all of your images automatically, as you are uploading them. No reason not to install this one. It that will drastically reduce the file size of an image, while not reducing quality.
Lazy load only loads images above the fold line of your website. When you scroll down to the lower parts of your website it will then load them.
This increases the pages loading time as it is not loading everything on the page at once.
Plugins like W3 Total Cache can be easily installed and will cache your WordPress posts and pages as static files. These static files are then served to users, reducing the processing load on the server. This can improve performance several hundred times over for fairly static pages.
This plugin should only be used with knowledge of caching as if not setup correct, can usually cause more bad than good. Learn how to optimize this plugin here.
And as for WP Super Cache, for the basics of the plugin, this is a lot simpler and it is as simple as Installing the plugin and turning cache on.
