We have received an email from yahoo search marketing team that transition to Microsoft has taken place for our account wef Oct 2011 and we will not be able to access any further data from yahoo search marketing after 04 Apr 2012. The transition is smooth to Microsoft but obviously their dashboard is not as smooth as we see in Google adsense. The email is as appended below:
As you may know, we've already completed the process of moving search ad serving for Yahoo! to the Microsoft in India back in October 2011. Your search ads are now served by Microsoft Advertising adCenter, and not by the Yahoo! Search Marketing platform, which will be no longer accessible after 4th of April, 2012.
As a result, the financial and ad performance reports and data will only be accessible in your Yahoo! Search Marketing account until 4th of April, 2012. Therefore, we recommend that you download any critical information at this time if you may need it in the future.
We appreciate your business and look forward to helping you successfully advertise on the Yahoo! and Microsoft search networks.
Your partners at Yahoo!
