I use a couple of different ways, At the moment I am using a site called Clixgalore, which has a PPC, lead and sale system depending upon the merchant, I have much more success with per lead and since putting up my new site on Saturday evening the site is upto $43 in clicks and leads. The leads seem to be generating the most revenue, as they are content related which is handy. When i first started I was putting ads that were high paying per <- snipped -> however that made me about 8$ in 2 weeks so i got rid of all of those and put ads that are related to the content, which seems to be working at the moment but whether they hold up is another story, oh yeah I am still waiting to get approved for adsense, and considering adwords.}}
