Microsoft’s search engine continues to show a deceleration in growth.

The quarter search advertising growth dropped below double digits, to 9% YoY (10% Constant Currency)

Microsoft, however, reports that revenue growth was supported by an increase in revenue per user, which suggests that user growth was even less.

It is clear, from the numbers, that despite continuing concerns about Google’s search monopoly, Microsoft has not been able to put themselves forward effectively as an alternative yet.
