What is Cloaking?
A website that returns altered webpages (different contents) to search engines crawling
the site is known as cloaking. In other words, a human reading
the site would see different contents or information than a search engine robot/crawler
reading the site.
Most of the time, cloaking is implemented in order to improve search engine ranking
by misleading the search engine robot into thinking the content on the page is different
than it really is.
Cloaking can be a dangerous method of getting listed in the search engines and may
not be recommended.
