adCenter is again increasing the percentage of MSN search results which display MSN ads as opposed to Yahoo Search Marketing ads.

Snippet of one of the emails I received via MSN about this announcement:

I want to share some good news regarding the adCenter pilot - we’re now ready to increase traffic to adCenter campaigns. We’ll be increasing traffic by approximately 70% from our current levels.

If you’re a pilot user, this means that your budget may be impacted due to the increase. Also, as more traffic is directed to adCenter, you should expect a decrease in traffic from your Yahoo! Search campaigns. You will be notified about the size and timing of additional traffic increases as we move towards launch.

The traffic increase is scheduled to begin on Monday February 27th. Pilot users should begin to see an impact on Tuesday February 28th, however, it may take several days to perform the increase.
