Cloaking is deceptive, directing users to pages completely unrelated to their searches. The intent of cloaking is to obtain good rankings by the content of the cloaked page, not the true content of the website. The search engines view cloaking as deceptive, and will punish sites that use such methods by removing those sites from their indexes.

Cloaking is a search engine optimization (SEO) technique in which the content presented to the search engine spider is different from that presented to the user's browser. This is done by delivering content based on the IP addresses or the User-Agent HTTP header of the user requesting the page.
