Pay per click sites sell advertising links to companies or people, and when you click these links, they pay you some of their profit, mostly 1 cent per click, and you get some percentage (mostly 50% to 100%) of the earnings of people that you refer. You get your money (mostly when you have a total of $10) by Alertpay and/or PayPal. Then you can directly transfer the money you earned to your credit card or bank account, or just spend it for shopping.
Above, you can see the best PTC sites, according to the points I gave them in my reviews, in the middle are these reviews, you can read them and choose which is best for you! And on the far right, you can see which sites paid me recently.
If you have any questions, you can e-mail me at buxreview@gmail.com, I'll be happy to help.
