b. The usage of Google search has reduced because of may be some competitor applicaton launch or some major marketing promotion activities
c. Some major technical issues has come up may be in the Google servers which is resulting in higher latency in Google Search applications resulting in reduced usage

Click Thru Rate might have gone down

2 Some technical issues like adds not displayed properly Same major flaw in random add picking might have got introduced
3. Some recent layout change has been there and peope are yet to get accustomed with the changed layout
