Wikipedia : "A reciprocal link is a mutual link between two objects, commonly between two websites to ensure mutual traffic. Example: Mr A and Mr B have websites. If Mr A's website links to Mr B's website, and Mr B's website links to Mr A's website, the websites are reciprocally linked. Website owners often submit their sites to reciprocal link exchange directories, in order to achieve higher rankings in the search engines. Reciprocal linking between websites is an important part of the search engine optimization process because Google uses link popularity algorithms (defined as the number of links that led to a particular page and the anchor text of the link) to rank websites for relevancy.
