 * === The DEEP WEB is called the invisible web because it cannot be searched by search engines such as Google. It is INVISIBLE to the spider technology that searches GOOGLE. ===
 * === This invisibility is caused by two things: ===


 * DEEP WEB pages are not STATIC web pages, always running, always the same. They are dynamic, created because of a QUERY from an individual.DEEP WEB sites tend to be less commercial or profit based than many surface web sites, although commerce has found its way to the DEEP WEB.

 * == Deep Web sites tend to be less commercial or profit based than many surface web sites, although commerce has found its way into the DEEP WEB. ==
 * === Because of a higher degree of authoritative or reliable information on the DEEP WEB many colleges encourage its use for research. The same is true for researches in any phase of life. In general terms, Deep Web sites have proven to be three times more reliable proportionately than Google retrieved sites. ===

 * === Complex lists of links to DEEP WEB sites selected for authority, quality or interest value by librarians or information specialists in some subject areas ===
