Most used search engines in 2016
Rankings & Comparisons
Tech Talker says:
"But what if I were to tell you that Google and other search engines can only search a fraction of the web. This number varies from source to source, but the most generous term that I've heard is that Google can search about 10% of the world wide web. So what's in the other 90%?"
Scientific American, April 20, 2014. "What Is the Deep Web?" | By Eric Escobar
• What's in the Deep Web?
This other 90% of the web goes by many different names: Dark Net, Invisible Web, Dark Web, Deep Web, Deep Net.
Just keep interchanging the words, "internet", "web", "dark", and "deep", and you'll come up with all of the "names" it falls under. For the sake of this episode I'm going to try and explain what these terms mean. Because the very nature of this stuff is widely unkown means that it often lacks official names.
"This other side of the internet is made up of a ton of different things. The broadest part of this side of the web is called Deep Web, Underweb, or Invisible web, this is basically everything that today's search engines can't make sense of. For instance, there's a lot of database information, dynamic content (like temporary webpages) and other obscure data that sites that Google don't deal with."
"Within this obscure jumble of stuff is what's called the Darknet. Now if the internet were like a big outdoor shopping mall, this side of the web would be like a dark back alley."
