Search engine optimization is an online marketing method which can bring immense traffic to your site. The lure of getting more visitors to the site compels users to use those methods which are not considered to be good by the search engines. One such method is of cloaking, which has literal meaning of concealing. So, this method seeks to conceal the real identity of the website from the search engines as well as the users and tricks them into visiting the website. The use of cloaking can be ethical as well as unethical in nature. Generally, this is the method which is not considered to be good by the search engines.
