Cloaking is a method in SEO that represents different content to human’s and spider bot’s. Cloaking is used by webmaster’s and SEO specialist to fool search engine’s algorithms and programmes to rank higher for desired keywords.This method is now a part of black hat SEO.
Cloaking is used to manipulate search engine’s. When a user will search for a related keyword, search engine’s will show links and description in search results. The User will click on a link on the basis of title and description, but the actual content on the webpage will be different from the content presented to search engine’s. This is known as “cloaking”.
NOW, search engine’s have changed their algorithm’s to fight against cloaking. Search engine’s like google, yahoo, MSN, Bing etc started banning sites use this method.

e)HTTP_referrer header cloaking: – HTTP stands for hyper text transfer protocol. HTTP_REFERRER is used in server-side scripting to analyse the source from where the user is redirected to our website.
