How Many Pages Are There On The WWW?

Indeed, most pages of information are beyond the reach of popular search engines. These pages are part of the invisible web. Bright Planet.com estimates the number of pages hidden from commercial search engines to be 400 to 550 times larger than what is available to commercial search engines.   These pages are part of the 'invisible web' estimated by Bright Planet to be as large as 3.5 trillion pages. Other experts feel the Bright Planet estimates are inflated, but still maintain that the 'invisible web' is from two to fifty times larger than the visible web. By the conservative estimate, we can guess at there being 50 to 100 billion pages of information on the invisible web.
