"You may have heard about private blog networks (PBNs) before, but you may not be sure what they are or why they are used," writes Kevin Rowe for SearchEngineLand. "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."
Rowe adds, "While these types of schemes were used commonly years ago, PBNs are now considered a pure black hat tactic and should be avoided at all costs, as they can lead to a loss in rankings, or even a manual penalty. PBNs usually provide little to no long-term value to the websites they are linking to."
