Everyone must be knowing about the PTC sites i.e. paid to click sites. Here you have to click on advertisements for a few seconds which varies from site to site. For this you will be paid a certain sum which maybe anything between $0.001 to $0.01 depending on the site. You do not require much technical knowledge for working on the sites. Most of the sites have a minimum payout. Once you reach the minimum payout of a particular site you can withdraw money.
Generally ptc sites are of two types-
(i) Bux sites (ii) Aurora sites.
Rate per click is higher in bux sites than in aurora sites.In bux sites you can earn money by only clicking on ads but in aurora sites apart from clicking ads you have paid to signup, paid to read ads etc.
Payment in ptc sites are mostly by two processes i.e. Paypal and Alertpay. Some may have both or some may have either of the two.
