Why is it free?
We share revenue with you. On average, about 10% of the adverts shown on your niche sites earn money for us, rather than you. This money is needed to pay for our servers and technical development / maintenance. If you don't make any money, neither do we, so we have a VERY strong incentive to keep the system in pole position and on top of search engine changes. We never bill you or charge you for our basic service, and you get paid directly by Google, or other PPC advertising providers. If you think that this kind of performance based commission is unacceptable, your recourse is very simple. You can go Pay Nathan Anderson $15,000 upfront and $500 a month, sucker. Oh, by the way, we do carry some affiliate adverts on our site - the particular hosting we recommend, for example, pays us a commission if you sign up. Note that we would recommend them even if we didn't get any kind of kickback, and that you can of course use any hosting company you like).
