Key points: Google and Yahoo edged higher in search share to 61.8% and 20.4%, respectively. That’s the first up month for Yahoo this year.

Microsoft dropped from 9.1% to 8.5% for the month. It’s important to note that Microsoft’s new Cash Back search program didn’t go live until May 22, so it will be interesting to see how they do next month.
