Sidebars are used to add content and features to your page. You first need to create the sidebars and then add widgets to the sidebar.
Sidebars
You can create a sidebar by going to Appearance > Manage Sidebars. Under Add New Sidebar, type a name for your sidebar and click Add.
Once a sidebar has been created, add widgets to it by going to Appearance > Widgets. You will see available widgets on the left side of the page and sidebars on the right. Simply drag and drop a widget onto the sidebar in which you want it to appear. Note that the Default sidebar automatically appears with Archives, Search Results, and when viewing single posts.
To get a sidebar you have created to appear on a specific page,
Edit the page.
Under Page Settings, select the sidebar.
Check the box to apply the sidebar to all child pages.
