Bing has introduced much more in-depth demographic targeting options that Bing advertisers can now utilize. Advanced Targeting as Bing refers to it allows advertisers to segment their audience by age, gender, device type, and time of day. Your bids will then automatically adjust to ensure visibility when your audience is searching.
US advertisers using Bing Ads are able to make use of the new Advanced Targeting right now; with this being slowly rolled out to all other markets.
