Known for: The Best Search Engine To Search People

As the name sounds this search engine lets users look for people. The searches are done based on the name and location provided by the searcher. Its results are much more accurate than those of Google is because they use ‘deep web’.

 The website not only produces links to all the profiles on social networks like Facebook, MySpace, and LinkedIn, blog mentions, and photos on Flickr but also finds mentions of the searched name in public records, including property records, SEC filings, and birth databases. It also finds e-mail addresses and summarizes “quick facts” about the person.
