link farm is any group of web sites that all hyperlink to every other site in the group. Although some link farms can be created by hand, most are created through automated programs and services. A link farm is a form of spamming the index of a search engine (sometimes called spamdexing or spamexing). Other link exchange systems are designed to allow individual websites to selectively exchange links with other relevant websites and are not considered a form of spamdexing.

A linking method which may have a spammy behavior to Search Engines.

A link farm is a Web page that is nothing more than a page of links to other sites. They are designed for the primary purpose of manipulating the results of research he has an advantage for the user or website owner yourself.

A link farm is a website set up with the sole purpose of increasing the link popularity of other sites by increasing the number of incoming links to those sites. They are typically made up of long lists of unrelated links. Some link farms are created as networks of sites that contain numerous links to one another.

Link farms are easy for Google to spot; since they all link to each other.

A better way to go about it is Mini Sites. Make 5 or 6 small sites (or more) that are created around specific (but different) keywords on your main site. Then each of those sites links to your main site only. Not to each other.

It would be good if they also linked to a few authority sites.

link farms are also linked to pages of links to other sites that do not apply to others. Somehow I like to see the links to the casino, as well as links to web development, education, real estate, and so on.

It is a consist of sites that link to other sites just for the purpose of linking and inflating a site’s apparent popularity. Further, some link farm products identify potential reciprocal link partners and offer to exchange links and create directory-like link pages for Web sites.
