Different sorts of links
Reciprocal link
A reciprocal link is a mutual link between two objects, commonly between two websites to ensure mutual traffic. 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.
Relevant linking
Relevant linking is a derivative of reciprocal linking or link exchanging in which a site linked to another site contains only content compatible and relevant to the linked site.
Three way linking
Three way linking (siteA ⇒ siteB ⇒ siteC ⇒ siteA) is a special type of reciprocal linking. The attempt of this link building method is to create more “natural” links in the eyes of search engines. The value of links by three-way linking can then be better than normal reciprocal links, which are usually done between two domains.
