Although "Related Posts Widget" and "Popular Posts Widget" are important for all types of blogs, but in blogs where almost all the posts are similar (like blogs with articles on recipes, money-making, computer tricks or automobiles etc.), visitors usually do not mind reading some quite-unrelated posts too. So along with Related Posts widget, a "Random Posts widget" on your blog will help you to increase the number of page impressions.

Adding a Random posts widget is very easy...
Simply log in to Blogger, go to Layout, click on "Add a Gadget", and select it as "HTML/JavaScript" type.
