What is Link Farms?
Link Farms is A link farm consists of sites that link to other sites for the sole purpose of increasing their link popularity score. Unlike perfectly valid links to sites with related information, sites that participate in link farming contain links to totally unrelated sites. This practice is also referred to as link stuffing. Google hates link farms and labels the links they generate as spam. In fact, Google gates them so much that some sites get removed from the index if they’re affiliated with link farms. Spooked, some web masters are considering removing all outbound links from their sites.
