MSN now offers publisher placement performance reporting. This should lead to better Content network performance. Here are a couple notes:

• Much like Google placement performance reporting, it shows a URL’s performance on the Content network. However, it also shows performance on the MSN Search Network (information which Google does not provide)

• From what I can tell, you can only pull data as far back as 5/14/09

• You exclude at the campaign level (via the change settings link), and this only applies to content. So for now, you cannot exclude search network sites

Nice job, MSN!
