Deep web

The deep web is part of the Internet that's not indexed by search engines. It includes sites that are password-protected (such as your bank account and shopping carts) and pages which are not linked by other pages. It's believed that the deep web holds about 91,000 terabytes of information. On the other hand, the surface web, or the pages which Google can get to, contains only 167 terabytes. So deep web is 545 times bigger than surface web, or in other words, surface web is 0.18% the size of deep web.
