Link farming is a questionable search engine optimization (SEO) tactic in which a website enters a relationship of reciprocal linking with another site or pays a provider for a large number of inbound links. Because many search engines use inbound links as a factor in determining a website’s page rank, websites use link farming to boost their rankings in search engine results.

Although relevant inbound links are an important component of website SEO, this should not be confused with listing a site on a link farm, which does nothing more than link to other sites in a group.
