As a Bing Ads publisher one wonders that where all the advertisements are being shown than on our research we found that ads are displayed on all search networks. These are Bing and Yahoo! search and syndicated search partners.
The ads you create in Bing Ads can appear on a variety of Microsoft properties, such as Bing search results pages, relevant MSN-affiliated websites and Microsoft Office—to name a few. They may also appear on Microsoft partner sites like Facebook and the Wall Street Journal Digital Network.
