Add Random Posts Widget to Blogger

The Random Posts widget or gadget for Blogger will display random posts added to your blog that, due to the natural structure of blogs, could get lost easily deep in your archives. Most of the time, when new people join your site, they rarely bother going back to find one of your good posts.

One of the easiest way to give a new life to your older posts is to display them in a random order in the sidebar. So, in this tutorial, I will show you how to add a random posts gadget in a Blogger blog. The advantages of this widget is that it can be easily customized and is loading pretty fast, besides displaying the thumbnails of your posts and how many comments they have received.

Do you want to add it? Just follow these steps below:
