Hi,
Before you join any paid per click programs you want to do your research on it. The biggest complains for many places has been that they don't pay. Many times there is not enough money in the company to pay the people who view the ads because of the low amounts involved. To pay for the website, the domain name and everything else some of the advertisement money is taken for those expenses. If the site is a big site there are a lot of people earning money and without enough reserves, a sudden cash out can put the website under.
