# Search Engine Discovery

Search engines can be very useful for finding information about the target. Search engines can be used for two things:

* Finding sensitive information on the domain that you are attacking
* Finding sensitive information about the company and its employees in on other parts of the internet. Like forums, newsgroups etc.

Remember that the world is bigger than google. So test out the other search engines.

Baidu, binsearch.info, Bing, DuckDuckGo, ixquick/Startpage, Shodan,PunkSpider

Google is a good tool to learn more about a website.
