11.5 Billion "Visible" Web Pages Are a Fraction of All Web Content

A new study reports the size of the “visible” or “indexable” Web (“the part of the Web which is considered for indexing by the major engines”) is currently 11.5 billion pages.
While that number is indeed strikingly large, consider that according to another study, 84 percent of the information available on the Internet is found only on the “invisible Web,” or “deep Web,” and is not visible by the major search engines.
To find out more about the invisible Web and learn how to alter your search strategies to find this content, see my article, Searching Smarter: Finding Legal Resources on the Invisible Web. Or sign up for my Conquering the Invisible Web workshop at the Wisconsin State Law Library on August 10th.
