Search engine king Google claims its index now surpasses trillion unique web pages.
After years of silence about the vastness of its Web index, Google announced Friday it had found 1 trillion unique Web pages. "We're proud to have the most comprehensive index of any search engine, and our goal always has been to index all the world's data," a Google spokeswoman said in a statement.
A bit of history: In August 2005, a similar claim put forward by Yahoo that it had indexed 20 billion URLs prompted a public rebuke from Google. "Our scientists are not seeing the increase claimed in the Yahoo index," a Google representative told blogger and search expert John Battelle.
A month later, Google asserted it had indexed 26 billion URLS and was "more than 3 times larger than any other search engine."
