The idea of getting website traffic for free is always appealing. After all, you should be able to make money out of the average website visitor, whether that’s by them clicking on adverts or (better still) paying you for products or services that you sell directly or via a commission program.
Of course, apart from the air we breathe, nothing in life is really free. Which means that you’ll probably be trading your time to create whatever it is that is getting you the free traffic. But that goes for anything.
