Basicly at all of these PTC sites you click daily on links and view advertisers ads or sites for 30 seconds. For that you get paid 0,01$ click. And if you have direct or rented referrals you get 0,01 - 0,005$ for their valid clicks as well. And if you think what is the potentional with 100, 1000 or more referrals, You should get the picture ;)
These PTC sites get their income from advertisers that are ready to pay for promoting their site or product. Also if you are launching a new website, placing ads to PTC site is great way to drive some traffic to your newly created site.
I have tested few of these Paid-to-Click sites and there is one that is pointing out from others, NeoBux. They have really professional management and great service.
And from banner above you can see my income from NeoBux this far, stats updated daily :)
NeoBux system isnt the simpliest there is, but it is the far best one. So time spent learning is like putting money in to bank. Just that intrest rate here is way better ;)
Feel free to comment and ask question if you have doubts about NeoBux.
