I think these graphs are based on the reported number of queries from the companies themselves. But I think Google has always publicly under-reported the number of search queries they get. So I suspect the number is higher than we're seeing on this page, perhaps by quite a bit. (Google says "Every day Google answers more than one billion questions" [1]. But that number hasn't changed in years. And technically ten billion questions a day is more than one billion.) http://www.google.com/competition/howgooglesearchworks.html http://www.google.com/competition/howgooglesearchworks.html
