From what I understand Google advertises your webpage and every time someone clicks it you must pay Google.
I have researched it a bit and found that it can be quite expensive. I also know that you can set a budget. But depending on how much it is I can imagine it would be hard to make a profit.
What exactly makes the price of PPC fluctuate? say 10 cents a click or 10.00 a click? I find this idea of Affiliate Marketing very interesting but I am not sure how to go about it.
I have used Google but just get confused because it goes into extreme detail.
Any help on this subject would be appreciated.
