Invisible web

"There are parts of the Internet that search engines simply can't see. The search engine's robotic "crawlers" either miss or are locked out of these areas on the Internet. Behind the barriers lie treasure troves of quality information. Collectively this informatin is called the Invisible Web.

  • webpages that have been deliberately excluded by owners - privacy issues
  • webpages that are dynamically assembled from online databse content (airline)
  • password protected services, databases and webpages (Groliers, Proquest)
  • non-HTML resources like some image, audio, animation and PDF files

"The Invisible Web is a vast part of the Internet that the search engines can NOT—or simply don't—include in their indexes of the Web (Gary Price)

You can GET TO the database, but you CAN'T GET INTO it - just with a search engine.

Are you aware that when you use a regular search engine, you are searching less than 10% of the actual web? that the inaccessible part of the web is 500 times larger than what is reached by regular search engines? and that the web is now estimated to be 300 billion pages? and is growing all the time?
