Yeah, that’s grossly wrong.
If it’s not indexed it is the deep web. I was wrong though... Only 4% is indexed not 10%. I was being generous. Every estimate you find will say the same thing. Seriously... It’s huge and we actually use just a small part of it that is indexed by search engines.
Oh I see, you somehow mistook what I said... I said nothing about “hidden services” at all, that is a different category altogether. I was talking about the deep web as a whole. Everything that is not indexed.
