A new Segment tab in the campaign tables will enable to you see performance by time, network, device and top vs. other right in the main campaigns interface. Once you select a segment, you’ll see details for your chosen metrics.
You can also download segmented data right from the campaigns interface as well. Click on the Download tab in the same secondary navigation as the new Segment tab and select your segment, just like in AdWords.
This isn’t rolling out right away. Instead Bing Ads is going to trial it through the holidays. To get in on the preview phase, email bingads-segmentation@microsoft.com.
