What is Black Hat SEO?

In search engine optimization (SEO) terminology, Black Hat SEO refers to the use of aggressive SEO strategies, techniques and tactics that focus only on search engines and not a human audience, and usually does not obey search engines rules. Some examples of Black Hat SEO techniques include keyword stuffing, invisible text and doorway pages. Black Hat SEO is more frequently used by those who are looking for a quick financial return on their Web site, rather than a long-term investment on their Web site. Black Hat SEO can possibly result in your Web site being banned from a search engine, however since the focus is usually on quick high return business models, most experts who use Black Hat SEO tactics consider being banned from search engines a somewhat irrelevant risk. Black Hat SEO may also be referred to as Unethical SEO or just spamdexing, as spamdexing is a typical frequently used Black Hat SEO practice.
