A "link Factory" (also known as a "large number of link mechanisms") refers to a network system consisting of a large number of web pages interleaved. These pages may come from the same domain or multiple different domains, and may even come from different servers. A site joined such a "link factory", on the one hand, it can get all the pages from the system link, while in exchange it needs to "dedicate" its own links, this method to enhance the link score, so as to achieve the goal of intervention link score. Now search engines have found them effortless. All sites in the link factory are found to be irrelevant, whether intentionally or unintentionally.
