A link farm is a Web page that is nothing more than a page of links to other sites. Link farms can be advertised as services that deliver you “high quality link building” services. But buyer beware!
Have you ever seen a website with a bunch of website links and nothing else? Usually there is nothing of value to you when you end up on the page, often you will see a ton of gibberish that is completely unreadable and then a hundreds of links. That is most likely a “link farm”.
Search engines can detect link farms easily and they shouldn’t be seen as a legitimate long-term search optimization strategy. Today, submitting to some ‘Link Farm’ or FFA site may be harmful to your website and your online reputation.
Link farms were originated in response to Google’s ranking system, PageRank. PageRank thinks of links as votes for your website, where one page linking to another page is like casting a vote. Therefore, websites with the most links received higher rankings.
Link farms were then created to help increase PageRank, however, in recently, Google and other search engines have created algorithms to prevent link farms from appearing at the top of search engine results pages (SERPs).
Web sites that have created link farms can be penalized by Google and other search engines.
