A script detects when a visitor is a search spider examining the site, when the search engine is examining a page, a version that meets all the search guidelines is presented, when anyone else visits, a sales page with various deceptive tricks and links to fraud sites may be shown.
A site may be quickly removed when cloaking is detected, in some cases by human reviewers Google is now more heavily employing.
Black hat experts will use cloaking on their disposable perimeter properties and not their more valuable sites.
Cloaking is a technique used to deliver the content on a Web page to a search engine in such a way that different content.
In simple words we can say when a blogger or a content writer of a web page, designs the page in such a way that it appears different to the web crawler and viewers. This black hat technique to get more traffic or to improve the page rank is known as Cloaking.
It is UN-moral black hat SEO strategy. The developer composes a substance for web search tool reason, yet not for the visitors. Thus, the web index sees one substance, yet visitors sees other substance. It's violation of Google webmaster rules.
Cloaking refers to the practice of presenting different content or URLs to human users and search engines. Cloaking is considered a violation of Google’s Webmaster Guidelines because it provides our users with different results than they expected.
Some examples of cloaking include: Serving a page of HTML text to search engines, while showing a page of images or Flash to users Inserting text or keywords into a page only when the User-agent requesting the page is a search engine, not a human visitor. If your site uses technologies that search engines have difficulty accessing, like JavaScript, images, or Flash, see our recommendations for making that content accessible to search engines and users without cloaking.
It is un-ethical black hat SEO technique. The programmer writes a content for search engine purpose, but not for the people. Consequently, the search engine sees one content, but visitor sees other content. It's violation of Google webmaster guidelines.
Cloaking is a search engine optimization (SEO) technique in which the content presented to the search engine spider is different from that presented to the user's browser. This is done by delivering content based on the IP addresses or the User-Agent HTTP header of the user requesting the page. 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, or that is present but not searchable. The purpose of cloaking is sometimes to deceive search engines so they display the page when it would not otherwise be displayed (black hat SEO). However, it can also be a functional (though antiquated) technique for informing search engines of content they would not otherwise be able to locate because it is embedded in non-textual containers such as video or certain Adobe Flash components. As of 2006, better methods of accessibility, including progressive enhancement, are available, so cloaking is no longer considered necessary by its proponents.
