Cloaking is a type of software that allows a site to selectively display pages to visitors. Usually the separation is made at search engine spiders vs. regular human visitors. The intention is to serve attractive pages to human visitors while serving search engine spiders a version that is easily indexed and better optimized. Cloaking is also used in cases where the page would otherwise not be indexed by a search engine at all. For example when using flash, or excessive javascript, or many levels of nested tables. In this case being able to present a simple HTML version of the page to a spider is very helpful in getting indexed and ranking well.- Category ID : 56886
