Cloaking

Cloaking is a black hat SEO technique. It’s submitting a page to the search engine that’s been optimised for the algorithm that determines the page’s position. So the search engine will show the page in a better position. But the problem is, the visitor sees a completely different page that wouldn’t have been ranked by the search engine in the first place. As this is a black hat SEO technique, the site using it can also get penalised.
