Almost two-thirds (63.5%) of all Internet searches are done on Google, according to the comScore 2008 Digital Year in Review. (Requires registration and .pdf download.) That’s up from 58.5% the previous year. Of the 137 billion estimated total searches performed in the U.S. last year, 85 billion were done on Google.
What is even more impressive is that Google accomplished this growth while all other search engines statistics were flat for the year.
