Grey Hat SEO describes the practice of using both black hat and white hat SEO techniques, often in ways that leave room for argument as to whether they're black hat or white hat. Grey Hat SEO is also used to describe any SEO techniques that haven't been judged as black hat or white hat by the major search engines.
