Upgrading to Content Ads on January 25, 2007 This week, some of our U.S. advertisers received an e-mail notification that their accounts will be migrated to our Beta site on Thursday, January 25, 2007, as part of the adCenter Content Ads pilot program. The e-mail notification also explained that the campaigns within migrated accounts will automatically be expanded to include distribution on content pages within the Microsoft network.
The adCenter blog has a whole FAQ about content adverts if advertisers have any concerns.
Much like Adwords & Yahoo, adCenter will provide advertisers with the ability to set content bids seperately from search at both adgroup and keyword level. Instructions can be seen over at the adCenter blog.
