Cloaking in SEO

Search engine optimization (SEO) is important to the success of a website. However, successful search engine optimization takes time. Many webmasters don't want to invest the time and work that's necessary to optimize a site.For that reason, some webmasters use cloaking to get their websites listed on search engines.


What is Cloaking?
A website that uses cloaking recognizes search engine spiders by their IP address. It returns web pages to search engine spiders that are different from the web pages that web surfers see. Usually, the cloaking software creates hundreds of web pages that are optimized for a special search term so that search engine spiders get the impression that the website contains a lot of relevant information about a special topic.

If you often search on Google then you probably can confirm that you can get good results with cloaking. You can often find web pages on Google that have little to do with the description on the result page.

Types of Cloaking

HTTP_REFERER Header Cloaking - if a user is coming from a certain website (e.g. clicking a link from search results or a website) they will be presented a different version of a website based on the HTTP_REFERER header value.

HTTP Accept-Language Header Cloaking - may be used to show different versions of a website based on a users web browser language without letting them for an option of language selection.

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.

JavaScript Cloaking - users with JavaScript enabled browsers are shown one version while users with JavaScript turned off (like search engines) are shown another version of a website.

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.
