Visible versus Invisible Web “Visible Web” (often called “Surface
Web”) Stuff you find via search engines like
Google, Yahoo, Bing, etc.
“Invisible Web” (often called “Hidden Web” or “Deep Web”)
Things not searchable by regular search engines
Subscription databases
Visible Web
Last year Google indexed its trillionth webpage (1 trillion unique URLs)
Google has indexed about half of the Visible Web
Results are relevancy ranked Over 200 factors determine relevancy Popularity is a large factor Hits a page gets is another factor
Invisible Web
Invisible Web is anywhere from 100 to 500 times bigger than the Visible Web (or even bigger?)
Search engines like Google can’t index the Invisible Web because:
Items found via a query Passwords
Invisible Web is important Search engine relevancy rankings for
Visible Web sometimes aren’t all that relevant
Some tools to help navigate Visible Web to find better resources:
