No, the &quot;deep Web&quot; is things like friends-of-friends Facebook posts, Twitter posts to locked accounts, and friends-locked LiveJournal posts — things that are in some sense &quot;on the web&quot; but that a standard search engine can&#x27;t find.  You&#x27;re thinking of the &quot;dark Web&quot;, which includes things like onion sites.  Your confusion is not unusual; <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Dark_web" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Dark_web</a> says, &quot;The dark web has often been confused with the deep web, the parts of the web not searched by search engines. This confusion dates to at least 2009.&quot;
