Bid adjustments in Bing Ads allow advertisers to increase or decrease bids for specific targeting criteria, such as device type, location, demographics, or time of day. For example, if mobile users convert at a higher rate, you can increase bids for mobile traffic to capture more conversions.
Similarly, you can allocate more budget to regions or age groups that perform better. Bid adjustments help optimize ad spend by prioritizing high-performing segments while reducing waste on less effective audiences, ensuring better overall ROI.
