1.
SAFETY FIRST! If you don't already have your computer protected, go to http://pack.google.com and get yourself a copy of Spyware Doctor. It is a free product. Download it and set it up to run once a day to make sure you don't pick up any nasties.
2.
Go to your search engine -- like google or yahoo -- and type in 'pay to click sites' or 'PTC sites'. You will find reviews of many sites and you can decide which ones to join.
3.
GET PAID! Most of the sites will pay you to either your Paypal account or your AlertPay account. These accounts are free and you can transfer your earnings from them right to your bank account.
4. Bookmark your PTC sites and visit them once or twice a day. Click the ads and remember to request payout once you have reached the required number of clicks.
5. You can earn more by referring your friends. When they register using your special link, and they click an ad, you will receive a tiny bonus for each one of their clicks. Kind of like free money! :)
