If you are a Microsoft adCenter advertiser, I recommend you login to your account and check to make sure that the conversion tracking part is set to the way you like it. Two advertisers noticed over the weekend that the conversion tracking feature was turned off on some of their campaigns, for no apparent reason.
Log in this morning and the conversion tracking is turned off for both accounts. Instead of seeing the number of conversions, it said "Off (Enable?)" and the enable text linked to a page to enable tracking and provided the code snippet.
Gave MS a call and they have no reason as to why this happened...way to go! I have lost important data for my accounts = not happy.
Interesting. So just log in and double check you are set.
