The admin area of WordPress is sometimes referred to the back end of your website and it’s where you can configure the settings of WordPress, install themes and plugins, publish content, and more.
What you will see when you login to your website’s admin area will vary depending on a number of factors. Your user role will play a large part in what elements are available to you, although if you are the owner of the website, you will likely be using the administrator role and have access to all of the capabilities of WordPress.
Any WordPress plugins or add-ons that are active on your website will also more than likely leave their mark on the admin area. This usually takes place in the form of additional top level menu items that are added to the left-hand sidebar menu, or new items that are added to the sub menus. Some themes can also modify the WordPress admin area in the same way, as well as adding custom controls or panels to the dashboard.
As each WordPress installation will grow and evolve in its own way, for the sake of clarity, this guide to the admin area of your website will be working from a fresh installation of WordPress.
