Blekko's new Grep tool shows that 1.3 Billion URLs on 12.4 million domains are using Google Analytics. http://blekko.com/webgrep?page=view&id=f6c212b83629fe094e0121c9c5ffea2b http://blekko.com/webgrep?page=view&id=f6c212b83629fe094... Not sure how big their index is right now, or how that compares to the entire web, but it is a big number regardless. Edit: On their announcement of the Grep functionality, Blekko says they are running it against 4 billion pages. This is still only a portion of the web, but that puts it around 1 in 4 pages having Google Analytics installed.
