Widgets are blocks of information (or functions) that can be added to a WordPress site through the sidebars or the footer. Sidebars are designated areas on your site where you can add widgets. The availability of sidebars vary depending on the theme you are using for your project. However, often times you will find that your site sidebars will be located on the right (or left) side of your content area as well as below the content area.
Add Sidebar Widgets to Your WordPress Site
Add a Widget to your WordPress Site
Navigate to the Dashboard of your site.
In the “Dashboard”, on the left side of the page, under the toolbar, click Appearance, then click Widgets. The “Widgets” page will open. Available widgets will be on the left side and available locations on the right side.
From the right on the “Widgets” page, drag and drop an available widget to the location you want it. The widget will be listed as part of the sidebar or footer and remain selected showing its personalization options.
Note: As soon as you drop the widget into a location, the widget will be available on the site. You are not required to click Save.
Optional: Complete the personalizations options.
To confirm changes, click Save. The widget will be updated with the new information.
