Link Farm

Link Farm - a web site or circle of web sites with no real content that try to direct traffic to other sites. Typically a link farm is linked in with many other link farms. These link farms all reference each other. The usual technique is to offer free product and have that one web site out of the twenty that has real product which charges for it.

If you want to find a link farm it is easy to find one either in the "free web graphics" or "adult" industries.
