What YOU need to make this work for you:
1) A blogger blog.
2) Blogger blog must have Pagerank 4 or you know how to get it a pagerank 4.
You can have a new blog, but you need to know how to get traffic. No traffic no money.
For Newbies, you just put this thing on your blog. You need traffic though!
For Experienced, this will work perfectly for you assuming your blog gets some traffic, or it has a good pagerank.
It took me 30-60 minutes to do it, last year, on May 2007. This month, April 2008 I made another sale from this thing. Almost every month of 2007 I earned something!
Best of all I only did it once because I was busy. You can do it over and over again, on as many blogs as you have... and even on the same blog several times.
I realized this technique is making me money, after thoroughly checking my Clickbank Stats.
