What does cloaking checker tool do in seo?

[sonia sharma]

Cloaking involves showing one version of a Web page to users and a different version, usually stuffed with other keywords, to the search engine spiders. The SEO Cloaking Checker detects whether a Web site uses "cloaking," a server technique that some sites utilize to try to fool the search engines into awarding rankings the Web pages do not deserve. This is a stealth method that Google and the other search engines consider deceptive, since it attempts to bias the spiders into ranking the Web page undeservedly higher or for a different keyword term.
