Definition Deep Web

The deep Web, sometimes called the invisible Web, is the large part of the Internet that is inaccessible to conventional search engines. Deep Web content includes email messages, chat messages, private content on social media sites, electronic bank statements, electronic health records (EHRs) and other content that is accessible over the Internet but is not crawled and indexed by search engines like Google, Yahoo or Bing.
