Hidden wiki (also known as the Invisible Web and the Dark Internet) refers to the hidden internet content not indexed by normal search engines. Some estimates are that the Deep Web is 500 times larger than the surface Net (the visible Internet). Feel 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 below the surface and captures things unseen to the eye.

Why is the Deep Internet invisible? Mainly because its challenging-to-come across web internet sites and search engines:

May have inadequate links to their content

Need customers to register

Have spotty indexes to their content material.
