Google Adsense
Its the best known advertising programme and higher paying programme in the advertising PPc world.It has the rates of nearly 40cents/click and the refrral programme is also quite good.They pay you 255$ per refrral when your refrral reaches the payout of 100$ within six months.when you refer 25 person and they reach their respective payouts within 6 months of their start adsense rewards you 2000$ bonous.
Widgetbucks
It is the new hot player to enter with a boom in a ppc world.The most interesting thing is it gives signup bonous of 25$ to attaract customers.More than 5000 people have joined this programme in the 1st week itself from its starting date on oct 2 -07.they are promising the ecpm rate of 3-4 $ /click.the referral prog. is also good which pays you the 10 % commission of what your referral earns for 12 months.But the negative side of this prog. is that they are not clear on their part of payments and the customer care centre is inactive which is the real test of genuineity.
