Google and ComScore.

NASDAQ is up almost 3% dragged by positive sentiment in tech. All these happened after Google (GOOG) tops analyst estimates for Q1. And Google shares are high flying more than 20%. But there is something sad about the story. You remember recent statistics released by ComScore (SCOR). Reporting y-o-y 1,8% growth for paid clicks for Google. And Google's report shows 20% rise. Of course those are 2 different numbers as ComScore announced US paid clicks and Google's number is for global growth. But still this inconsistency is raising question Can you measure (predict) by ComScore?
Not really.
