Semi-natural linking arises from building relationships between Web sites for non-search related purposes — brand and visibility building, traffic building, and community building are the three main sources that I see today for Semi-natural linking. Site-wide links can actually occur in these kinds of relationships. For example, suppose four people set up a forum on a special topic near and dear to their hearts. Each of them has a Web site. They each add a link to their mutual forum (hosted on a fifth domain) to their navigational links. That forum just received four site-wide links. They didn’t do it for the search engines, they did it to build visibility for their forum among their own visitors.
