The term Deep Internet (also known as the Invisible Net and the Dark Web) refers to the hidden net content not indexed by normal search engines. Some estimates are that the Deep Web is 500 times bigger than the surface Internet (the visible Net). Consider of dark web sites as the surface of the ocean-miles and miles of surface out there, as far as the eye can see. But when you cast a net, it goes under the surface and captures items unseen to the eye.
Why is the Deep Internet invisible? Simply because its hard-to-locate internet internet sites and search engines:
May possibly have inadequate hyperlinks to their content
Need customers to register
Have spotty indexes to their content.
