World Wide Web – Statistics
Between 2005 and 2010, the number of web users doubled, and was expected to
surpass two billion in 2010. Early studies in 1998 and 1999 estimating the size of
the Web using capture/recapture methods showed that much of the web was not
indexed by search engines and the Web was much larger than expected.
According to a 2001 study, there was a massive number, over 550 billion, of
documents on the Web, mostly in the invisible Web, or Deep Web. A 2002 survey
of 2,024 million web pages determined that by far the most web content was in the
English language: 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. As of March
2009, the indexable web contains at least 25.21 billion pages.
On 25 July 2008,
Google software engineers Jesse Alpert and Nissan Hajaj announced that Google
Search had discovered one trillion unique URLs. As of May 2009, over 109.5
million domains operated. Of these, 74% were commercial or other domains
operating in the generic top-level domain com. Statistics measuring a website’s
popularity, such as the Alexa Internet rankings, are usually based either on the
number of page views or on associated server “hits” (file requests) that it receives.
