Why should I use this extension

A normal web site is designed to be found in the internet.

This extension will serve the opposite function and try to hide the content. Search engines should only found not existing pages.

In that case this extension is designed especially for private usage. If you want to personally announce that you created a web page, e.g. to stay in contact with your family and friends across the word, and don't want to invite everyone in the internet, this extension could protect your pages against search engine bots. This extension could only be used as an additional features like using a login to protect your content. It could not replace any other type of data protection.


The detection of a search engine bot depends on the quality of Bot Detection engine. The Author BugBuster explicitly pointed out: "There is no reliable detection guaranteed." The search engines are detected by their user agent string and their IP address. BugBusters still collect a huge list of different and popular search engines and he still extends the quality of detection.
