Basics of Cloaking Cloaking generally means to present different version of web page contents from of search engines to search robots and human visitors based on their browser's user agent or IP address. It's a deceptive method used to cheat search engines in order to rank well for desired keywords. Not always but in most of the cases, cloaking is also used to trick users to visit certain websites based on their description in search engines. For example a user searching for some product may click on a website in search engine based on its description and title but the final website will not be the one described in SERP's. It will be a totally different one. Therefore, these practices that are designed to manipulate search engines and deceive users by directing them to sites other than the ones they selected, and that provide content solely for the benefit of search engines should be avoided. Different Cloaking Methods IP address Cloaking - a method of presenting different contents based on determining IP addresses. e.g. Search engines with certain IP addresses will be shown a one version of a web page and all other IP addresses will be shown another version. User-Agent Cloaking - a method of delivering different versions of a website based on User-Agent. e.g. Search engines and/or users using different versions of web browsers are served with different contents of a web page.
The most important aspect in digital networking is clocking. The clock that quantifies the analog signal must be the same clock that reconstructs the signal at the other end. The only way to assure that the clock is accurate within the entire digital network is to have only one clock.
