According to recent figures
How many Websites are there in the WWW?
Is in the 10's of Millions

Come a long way since Tim Berners-Lee & Robert Cailliau where the First Webmaster and Surfer Back in December 1990
When I Joined up there were ca.50 Million sites!(1999/2000)
Now? You tell Me (slightly more...)
The answer is amongst the Clues above

You say according to recent figures, Bedstor. How recent? As of Feb. 2007 there were about 109 million web sites.

My estimate comes from the fact that each web sites has about 273 pages in average and there were 29.3 billions of pages recorded on then. So now in 2008 , one year later, it would be a little more.

Mozart, is your list the "Live" list or the total to date? 107 Million is a piffling Number to what I have,and I have a nice chart on my link page
107 mill would place it at the end of 2006 on the chart
Mine are good for end of last year

Bedstor does your question involves "Blogs"?

Mozart. Its the Web as a whole entity

My source does not pick out any specific type of site

Over 100.1 billion websites operated as of March 2008.

Nice try dg but thats far too many..
Mozart is actually Quite close with his nuber , But is still several Million Plus short if the Mark
Make it easier I will show the answer if you get within 15 Million of the Number

So far you have estimated it @ ca. 125 Mill ... Want an advance on that Number

I got my figure from Wikipedia, bedstor. They in turn got it here: Domain Counts & Internet Statistics

I had a Larger Number of 162 Million off this site (Not Wiki)
Royal Pingdom » How we got from 1 to 162 million websites on the internet

The second link you gave looks a useful monitor(better accuracy)

So Mozart Point to you for a good guess

Both sources are Good Though I wonder if dgs Numbers(2nd link) are based on Western Domains?
Middle Eastern domains are on a Sharp growth and I wonder why the Country domains are off the List AHA! GOTCHA!
And Over the the Page we have those Country IP addresses Not adding those Up
Unknown by what factor on average somebody has made a site at any of these

Allowing for site name changes /changes of ownership ,failed sites and other factors

My Number I suggest, is Reachable if added to the other list ...I'm an good estimator not a Mathematician

Check these out ... they are jointly in last place if you want a near unique
Country domain where nobody goes often

8 SOUTH GEORGIA AND THE SOUTH SANDWICH ISLANDS
8 GUERNSEY
8 PITCAIRN

I think you're off a bit, Bedstor.

From Wikipedia -

According to a 2001 study, there were more than 550 billion documents on the Web, mostly in the "invisible Web", or deep Web.[12] A 2002 survey of 2,024 million Web pages[13] determined that by far the most Web content was in English: 56.4%; next were pages in German (7.7%), French (5.6%), and Japanese (4.9%). A more recent study, which used Web searches in 75 different languages to sample the Web, determined that there were over 11.5 billion Web pages in the publicly indexable Web as of the end of January 2005.[14]

Over 100.1 billion websites operated as of March 2008.[15]

The deep Web (or Deepnet, invisible Web or hidden Web) refers to World Wide Web content that is not part of the surface Web indexed by search engines. It is estimated that the deep Web is several orders of magnitude larger than the surface Web.[1]

In 2000, it was estimated that the deep Web contained approximately 7,500 terabytes of data and 550 billion individual documents.[1] Estimates, based on extrapolations from the study entitled How much information is there?, from University of California, Berkeley, show that the deep Web consists of about 91,000 terabytes. By contrast, the surface Web, which is easily reached by search engines, is only about 167 terabytes. The Library of Congress contains about 11 terabytes, for comparison.[4][5]

5 ^ The unpublished paper How much information is there in the world?, by Michael Lesk in 1997, estimated that in 1997, the Library of Congress had between 200 terabytes and 3 petabytes.

The correct answer is, of course, unknown, but it is obviously in the billions.
