Microsoft will now be the exclusive salesforce for ads on the Bing Ads platform. This will provide a single, unified customer experience and increased connectivity between Microsoft advertising products. For Yahoo desktop search, Microsoft will serve a minimum of 51% of ads, which is close to the 99% it currently serves. Yahoo mobile search will remain non-exclusive and non-guaranteed, though Microsoft currently serves around 90% of this traffic. The changes provide an opportunity for more search volume and partnerships, along with faster innovation through more direct feedback to engineers.
