Cloaking - SEO Glossary
Cloaking is the art of delivering different content to different users based on their IP address or user-agent string. There are a few different uses for cloaking such as delivering content to people from different countries. It is also used to deliver different search engine optimised content to the search engines and then different content to the users. This is deemed to be unethical in the eyes of search engines as people stuff the cloaked pages with links and repeat keywords in order to rank highly, while giving the users standard looking pages.
