In a nutshell, a widget is a cool little gadget you can add to a blog or website. There are all kinds of different widgets you can utilize to enhance the functionality or personality of your blog or website.
Adding a widget to a WordPress blog is fairly simple. Just head to your dashboard, scroll down until you see a button for “appearance” on the left side bar. Hover your pointer over it until an arrow appears (unless you already have the menu open). Click the arrow to open the menu and select “widgets”.
This will bring you to a menu where you can select your widgets. Go ahead and add some widgets to your WordPress blog or learn more about them. To add them to your blog, simply grab the widget (the little gray boxes) and drag it over to the right side bar in the respective widget area. Try out different widgets and areas to get the desired effect.
I added several widgets to enhance my blog and integrate my social interconnectivity with widgets for twitter and del.icio.us. It even prompted me to get set up on flickr so I could show off my hobby photography.
