If you follow the directions above you will be creating an account with Google's AdSense program and you will be posting three banners on all of your blog and profile pages. From those three banner placements you will earn 100% of the revenue. In addition, as you find other monetization opportunities, like text links (see below), you will be able to earn more money.
The amount you make blogging will be directly proportionate to how much effort you put into your blog. When you first start your blog you will be making very little because you don't have a lot of blog entries and you don't have a following of people reading your blog. If you continue to write an interesting blog people will continue to come back to read what you have to say. Interesting blogs have a way of taking off almost like a spreading virus as people talk about them and tell their friends about them.
