PCC means Pay Per Click. When you register any site and you click any of the advertisement you will get paid for that advertisement. Be careful and check about particular sites because most of the sites are not good at present. Also get news from your friends also about PPC sites.
It's not an easy road and takes plenty of patience and a willingness to lose some money in the beginning. If you can stick it out long enough then you are bound to learn what works and what doesn't work and make money. Some people make a ton of money doing this. You will want to first join some networks such as cj.com, affiliate.com, neverblueads, or others, find the products that interest you and then try using something like Google Adwords to promote this stuff. How to promote it or what kind of sites to build is just something you will have to learn as you go. Find out what works and just repeat the process. It can be extremely frustrating, but if you stick to it, you're bound to make money. The key is not giving up. Good luck man.
