What you have to do first is create a nice blog full of useful info and drive traffic to it. Then you will be able to monetize it with the following method * CPC (adsense, bidvertiser, clicksor) * CPM ( advpoints, cpx,,,) * CPA ( you can choose to chose adult affiliate as this will earn u much too)
The easiest and most efficient way for new bloggers is using adsense. You simply put it on your site and wait for people to click the ads. You need traffic of course though.
