you have to have valid and unique site traffic , what I have read over the net is all about content, content is king as I have mentioned on my previous replies, anything you can think of as long as it is related to your site, place it, it would give google much time to crawl your site faster with related content. a friend of mine has been doing this for 2 years and he just got his first pay check, well for me i just started it, as soon as i get mine (hopefully) im going to get a paid web hosting package from x10hosting possibly
