Certain links to external sites can negatively impact search engine rank. In particular, experts say that affiliate links and other paid links, which are used to provide revenue for a web site, will reduce a site's rank in search engines, especially if it appears that the site is attempting to add redundant links with their own affiliate code to the search engine results. Adding a rel="nofollow" attribute will tell the search engine not to index the target URL.
