Definition of Cloaking
Cloaking refers to the practice of showing different content to search engine spiders when they visit your site than users would normally see. Cloaking can be used to try and influence search engine ranking, although the search engines typically frown on any such attempts, and the penalty for detection can be removal from their index. There are legitimate uses for cloaking techniques that involve large websites that may need to save server load or that use it to circumvent the limitations of technologies that the search engines might otherwise not be able to read.
