Some peeps just gave you classified ads websites to advertise your blogsite. But no, you don't need those.
First things first.
In order to make your blog popular, you should have quality content/articles. And good taste for blog design too. Keep it simple, my friend. Most visitors don't want blogs with a lot of stuffs on their screen.

Signup your blog for Google Analytics account to track your blog traffic.
