Black Hat SEO
Generally used to promote scams and sites with little or no real content. The reason for this is that real sites with real content can get a high ranking based on legitimate content and links. For this reason, sites that use black hat techniques are generally regarded as useless or harmful. These techniques are so appealing is that they tend to have an immediate impact on search engine results with less work than legitimate SEO techniques.
Cloaking Pages
Presenting a different page to search engine spiders rather than to human visitors. This can be achieved by having a script detect the browser and display the page accordingly. The page that would be displayed to search engines would generally have a high keyword density. This can be the most devastating because cloaking can be used for legitimate reasons as well (such as to display a different layout to users with less functional browsers).
Hidden Text
Putting a mass quantity of keywords in such a way that human visitors can’t see them but search engine spiders can. This can be accomplished multiple ways such as making the text the same color as the background, or putting the keywords in alt and noscript tags. Hidden Link is similar to hidden text, but its intent is to create link popularity rather than keyword density.
