3 and 4 Column templates

In general, most of the blogs are in 2 column format. This will reduce the possibility of adding more gadgets and more ads.To avoid this, Few template providers like Eblogtemplates will give you 3 column and 4 column templates.You just download the code(free of cost) and add it to your HTML template code.Before you install the new template you must save the existing template code.

I prefer to select 3 column template, Because it gives you more options to add gadgets and ads.Also the 3 column format gives you a Good look.
