Hi
What you're describing has been sold for a number of years as the Google Cash method.
It's got more difficult over the years as Google have tightened up their rules for Adwords advertising.
If you're venturing into Adwords, Perry Marshall's guide is essential reading. At an absolute minimum, get and read his free email course.
Is there money in affiliate marketing? Yes. Especially if you are the one who created an in-demand product that lots of affiliates want to promote. But there's money even if you're promoting someone else's products.
Is there money in promoting Clickbank products through Adwords? Yes, but you need to know what you're doing or you could easily lose cash or be charged an arm and a leg for clicks.
Tread cautiously to start with. Monitor regularly. Test, test and test again (Perry's course will emphasise that).
Good luck!
