We recommend our Wordpress hosting plan if you want to get the best performance possible out of your Wordpress site. You can install Wordpress on a Wordpress plan using the Wordpress Toolkit:
Log in to cPanel > click on WordPress toolkit on the left
Plesk\cPanel (non-Wordpress) plans:
Log in to the control panel for your plan:
Once in Plesk go to: Applications > Featured Applications > Press Install beside the application you want to install
If you have an application already installed it will install to /application_name. Otherwise it will automatically install the application to the root of your website.
