So-called "reciprocal" links have a bad rap in so far as page rank is concerned. A reciprocal link is one in which sites trade links, often specifically as a means of improving page rank. Apparently, Google discounts so-called reciprocal links. This means that a page using reciprocal links would not benefit page rank.
The current Search Engine Optimisation wisdom is that Google favours so-called one-way links. As the name suggests these are links which point from one site to another site without any kind of reciprocal link.
