Paid to Click can be rewarding.... However, if you're serious about making money online; Adsense is a much more legitimate and sustainable business model. That said, I enjoy PTC programs (and also get paid to, paid surveys, etc.) and there are several new paid to click programs that pay free money to AlertPay; the new NeoBux for example. Several new GPT sites also pay to Paypal with a low minimum to get paid and some even pay instantly via Paypal's automatic API payment processing. At the same time, you have to be careful with paid to click programs... there are many "fly by night" PTCs that are paying one day, gone the next. Overall I've found them a nice way to make a little extra money on the side to supplament affiliate marketing, etc. Hope that helps and feel free to ask if you have any additional or more specific questions. Best & Take Care!
