Link Farm
01 Definition
Link Farm meaning: A group of sites created mainly to link to each other and inflate rankings.
A link farm is a network of low-value websites or pages that exist chiefly to exchange links and pass authority. It is a classic manipulative scheme that violates Google's spam policies. Links from link farms are usually ignored or penalized, and participation can trigger a manual action.

Why it matters
How Link Farm fits the work
Recognizing link farms matters because links from them carry little value and being tied to one can put your site at risk of penalties.
In context
A cheap package added the site to a network of 300 interlinked blogs, and rankings dropped once Google devalued the farm.
Practical note
Avoid any service promising hundreds of quick links; these are often farms. If found in your profile, evaluate whether the links are self-built before considering a disavow.
