A new technique of Spam is here on the board, it’s named as Mosaic Cloaking. Well its purpose is same to get your webpage ranked high on search engines, but its slightly different form the Normal cloaking technique.
In Cloaking the content presented to the search engine spider is different from that presented to regular web surfers. When a user is identified as a search engine spider, a server-side script delivers a different version of the web page, one that contains content not present on the visible page.
Where as in Mosaic Cloaking only a part of a webpage is replaced. For example, the blank space on a web page might be filled with keyword rich text when a search engine spider requests a page. The rest of the page remains unchanged.
But the after effects of both the types of cloaking are bad. Later or sooner search engine crawler will get to know about these Spamming techniques and will remove the website from their index. All major search engines consider cloaking to be a violation of their guidelines. For that reason, websites that use cloaking will be banned from the search results.
