The term Deep Net (also called the Invisible Net and the Dark Internet) refers to the hidden web content material not indexed by standard search engines. Some estimates are that the Deep Web is 500 instances bigger than the surface Web (the visible Web). Think of the surface internet 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 issues unseen to the eye.

Why is the Deep Net invisible? Simply because its challenging-to-find net sites and search engines:

May have inadequate links to their content

Require users to register

Have spotty indexes to their content.
