Setting up a website is easy and free. Anybody can setup a website using wordpress and get their affiliate links from clickbank or amazon. Buying a template simplifies the process, but it isn’t really too difficult to setup up one using the free methods.

Its absolutely correct that the key challenge lies in the effective marketing of the website. If there are hundreds of similar sites using the same 20 templates, why would anyone buy from yours, over another?

And if someone is really good in marketing their websites, they would probably prefer to select better affiliate products than those offered by this one site alone.
