Interdependence

The importance of interdependence on internet is enormous. If you want that few people saw your site, you must create links on another sites. Because the same sites could do the same thing. So you increase your chance for seing by more people.

For example, on the site "cuisinorama", you can learn how to do the cooking. The sites proposes links on cooking books on Amazon, and links on a site "chateauonline" which you coult buy wine . The site does many another links, with a supermarket "superU" or "lediet" a site whick explain how to lose weight.

An another example on Amazon : the site is a big succes because on almost all sites / blogs who speaks books, the links point on their site (like mine!).
