Cloaking is a Search Engine Optimization technique in which the content presented to the search engine spider is different from that presented to the users' browser; this is done by delivering content based on the IP addresses or the User-Agent HTTP header of whatever is requesting the page. The only legitimate uses for Cloaking used to be for delivering content to users that search engines couldn't parse, like Macromedia Flash.

Spamdexing or Search Engine Spamming is the practice of deliberately creating web pages which will be indexed by search engines in order to increase the chance of a website or page being placed close to the beginning of search engine results, or to influence the category to which the page is assigned. Many designers of web pages try to get a good ranking in search engines and design their pages accordingly. The word is a portmanteau of spamming and indexing.
