Black Hat SEO refers to SEO practices that are in violation of Google’s Webmaster Guidelines. Black Hat SEO attempts to manipulate their search engine rankings through means specifically and implicitly forbidden by Google. This can result in the sites being banned by Google, and no longer showing up in the search results of Google or its partners. Black Hat SEO marketers take this risk in hopes of getting fast results, typically on sites where it doesn’t matter if they get banned a month or two later.
