Originally, the process of exchanging reciprocal links with sites was designed increase search engine optimization (SEO) because the idea was to increase the number of sites that link to yours. In the early days, the more Web sites that linked to yours would enable your site to appear first, or higher, in organic search results. In the past, this number of links defined the level of popularity of your site among users of the Internet.

Search engines such as Google now consider link farming as a form of spam and have implemented anti-SEO tactics.
