Reciprocal link
From Wikipedia, the free encyclopedia
A reciprocal link is a mutual link between two objects, commonly between two websites in order to ensure mutual traffic. Example: Alice and Bob have websites. If Bob's website links to Alice's website, and Alice's website links to Bob'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 became an important part of the search engine optimisation process thanks to the link popularity algorithm PageRank employed by Google, which ranks websites for relevancy dependent on the number of links that led to a particular page and the anchor text of the link.

[edit] Three way linking
Three way linking (siteA -> siteB -> siteC -> siteA) is also a kind of reciprocal linking but a special case. This type of linking is becoming increasingly popular since some search engines are giving less consideration to the value of normal reciprocal links.
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.
[edit] Automated Linking
In order to take advantage of the need for inbound links to rank well in the search engines, a number of automatic link exchange services have been launched. Members of these schemes will typically agree to have several links added to all their web pages in return for getting similar links back from other sites.
[edit] Link Exchange
An alternative to the automated linking above is a Link Exchange forum, in which members will advertise the sites that they want to get links to, and will in turn offer reciprocal or three way links back to the sites that link to them. The links generated through such services are subject to editorial review.
