The Yahoo! and Microsoft Search Alliance is a major initiative between our companies to create a competitive choice in search for advertisers and consumers. The combined scale will assist both companies in speeding the pace of innovation to improve the search user experience, as well as help advertisers get better results and help improve monetization for partners.
Yahoo! and Microsoft will each provide customer support to different advertiser segments: Yahoo!’s sales team will exclusively support high volume advertisers, SEO and SEM agencies, and resellers and their clients. Microsoft will support self-service advertisers. In addition, Microsoft adCenter will be the platform for all search campaigns.
More volume, less effort.
Search ad inventory from Yahoo!, Microsoft, and their respective partners will be combined into a new unified search marketplace, giving advertisers of all sizes access to a combined audience of nearly 577 million searchers worldwide.1
Our aim is a high quality transition of advertisers and partners in at least the US prior to the 2010 holiday season. However, we may wait until 2011 if we determine this will be more effective.
