Google's paid-clicks in the US, the source of its fortune, showed weak, almost imperceptible growth for the third month in a row, according to comScore, just a couple of days before Google was scheduled to post its Q1 financial results. The tabulator says they were up only 2.7% in March and just 1.8% for the whole first quarter, a nasty, nasty drop from the 48% it supposedly recorded in the third quarter of last year or even its 25% growth in the fourth quarter.
