A link farm is a group of websites that exist purely to create artificial backlinks. They have no real content, no real audience, and no purpose other than inflating the backlink counts of whoever pays for them or whoever they target.
How to spot link farms:
Link farm domains typically have very low authority scores (DA Score under 10), generic or auto-generated content, hundreds or thousands of outbound links per page, and domain names that contain SEO-related keywords like "directory", "backlinks", or "seo-boost."
Why they are dangerous:
Google's algorithms are specifically designed to detect link farms. If your site receives many backlinks from link farms, Google may conclude that you purchased those links or participated in a link scheme, resulting in a manual action or algorithmic penalty.
Link farms vs legitimate directories:
Not every directory is a link farm. Legitimate business directories like Yell, Yelp, or industry-specific directories have real editorial standards and genuine users. Link farms have none of these — they accept any link from anyone.
