In recent years, the terms white hat and black hat have been applied to the Search Engine Optimization (SEO) industry. Black hat SEO tactics such as spamdexing, attempt to redirect search results to particular target pages in a fashion that is against the search engines’ terms of service, whereas white hat methods are generally approved by the search engines.

White hats tend to produce results that last a long time, whereas black hats anticipate that their sites may eventually be banned either temporarily or permanently once the search engines discover what they are doing.

Some of the blackhat SEO tactics include: keyword stuffing, hidden text and links, doorway and cloaked pages, link farming and blog comment spam.
