While adCenterís editorial guidelines are not exactly the same as in Yahoo! Sponsored Search, the differences are not significant. Additionally, Microsoft and Yahoo! will jointly review any discrepancies in editorial policies prior to beginning advertiser transitions, and make modifications as necessary to operate a fair and quality marketplace, and to make the transition as easy as possible for advertisers and publishers. Yahoo! will have the ability to continue to display some ads that Microsoft does not currently display on its own sites (e.g., adult ads), and vice versa.
One of our stated goals with the Search Alliance is to offer advertisers a single global platform with which to manage their campaigns. As far as YPN: Because the agreement between Yahoo! and Microsoft only recently received regulatory clearance, we have not had the opportunity to discuss this issue with Microsoft and make a determination as to YPN's future. We will certainly provide more details before the transition occurs.
Re interface: All Sponsored Search advertisers will use the adCenter platform for their paid search campaigns following their transition, and the "Panama" system will be decommissioned. Yahoo! will provide advertisers with direct access to 13 months of historical data from our Sponsored Search platform (Panama) for a specified time period following completion of the transition in each market.
Re languages: Microsoft has committed to continuing to improve its products to enable Yahoo! to deliver a quality experience to its advertisers and publishers. This very well could include adding new languages to support our global customers.
Re APIs: Yahoo! and Microsoft have not yet determined the specific plans for individual products and APIs. However, it is likely that the current YSM APIs will be replaced with Microsoft APIs.
