Cloaking. Sometimes, cloaking is considered a legitimate tactic by both internet users and search engines. One valid reason for cloaking is if different information is offered to different visitors like content behind a “members only” area. To be sure of the validity of this tactic, it’s good to contact each search engine, present your reasons for cloaking, and let them approve its use.
Paid links. Buying links purely for advertising purposes is considered legitimate while the practice of purchasing links only for the increase in link-popularity is considered an abuse and efforts will be made to either discount the links or penalize the site.
Duplicate Content. The practice of making duplicate content is considered legitimate on resource sites. These are sites that consist primarily as an index of articles on a specific subject matter.

Some people think that all SEO are either black hat or grey hat and that white hat is actually just good web mastering. While others still think that there’s no such thing as grey hats and that grey hats are just names they use if they are unsure whether it is a white hat or a black hat.
