CPA "cost per action" is by far the best way because you only pay for traffic that makes you a sale

it is easy to be punished by SE, if you cost per action.

1. The first thing that you need to do is to start commenting on other peoples blogs in order to get backlinks.
2. It was believed that you need to comment in your niche but apparently it also works on other blogs as well. So don't break your head over it comment everywhere, and leave your website link or the so called signature, best not of your main website but of your blogger or WordPress website. You don't want to jeopardize being spammed on your main website that is why we work from our blog, and promote from our blog to main site.
3. Google UP, blogs and comment on blogs on the first page with page rank, this is great. Remember Ive seen books talk about the "not in the niche" commenting and statistically it doesn't matter. Even if its not in your niche the results will be good.
