You may have heard about private blog networks (PBNs) before, but you may not be sure what they are or why they are used. A PBN is a network of websites used to build links (and therefore pass authority) to a single website for the purpose of manipulating search engine rankings. This scheme is similar to a link wheel or link pyramid, as it involves several different websites all linking to one another or to one central website.
