What do you mean by Cloaking?

[touchwood]

A website that uses cloaking recognizes search engine spiders by their IP address. It returns web pages to search engine spiders that are different from the web pages that web surfers see. Usually, the cloaking software creates hundreds of web pages that are optimized for a special search term so that search engine spiders get the impression that the website contains a lot of relevant information about a special topic.

If you often search on Google then you probably can confirm that you can get good results with cloaking. You can often find web pages on Google that have little to do with the description on the result page.
