In the right margin of the Blogs you can see how we can display different widgets. In this case we show our Blog Title and Tagline, along with Search, Categories, and Advertisement widgets. You are able to customize these any way you need to best suit your site.
Widgets are typically used in the sidebar for all sorts of different reasons. Think of widgets as little applications you can include throughout your website to make your website more appealing and interactive. In the case of our default database, we have a Blog Title, Blog Tagline, Search, Categories, Advertisement widgets and so on to make navigation and finding content on our site easier.
But widgets can even display calendars, social media updates, weather forecasts, recent comments, and all sorts of good stuff like that!
