White Hat SEO
Unlike Black Hat SEO, White Hat SEO involves strictly adhering to search engine guidelines and never using hackers tactics.
The term originates from American westerns, in which the hero often wore a white hat, as opposed to the villain who wore a black hat.
Since nothing is perfect, the most commonly used method of search engine optimization is called Gray Hat SEO: with this approach, webmasters interpret search engine guidelines fairly freely or resort to a few tricks.
