Link doping

Link doping refers to the practice and effects of embedding a large number of gratuitous hyperlinks on a website in exchange for return links. Mainly used when describing weblogs (or blogs), link doping usually implies that a person hyperlinks to sites he or she has never visited in return for a place on the website's blogroll for the sole purpose of inflating the apparent popularity of his or her website. Since the PageRank algorithms of many web directories and search engines rely on the number of hyperlinks to a website to determine its importance or influence, link doping can result in a high placement or ranking for the offending website (see also Google bomb or Google wash).
