What it is:
Use a Call Extension to provide a phone number that's not associated with a particular location but can be used for all locations where your ads are showing.
Call Extensions have the added benefit of allowing you to designate your ads as call only ads. When you select call only ads, website links in your ads are not clickable from a smartphone. Instead, your phone number is the only link that a user can click. Clicking on the phone number link will initiate a call to that number and you will be charged up to your bid amount (just as if the user had clicked on a website link).
With Call Extensions, you have two options: You can use your own phone number or use a Bing Ads forwarding phone number. When using a forwarding number, we assign a unique phone number that displays in your ad. When a customer calls this number, the call is routed to your business phone number. Our forwarding number allows you to track all calls from this ad, no matter where the call was made from, so that you can analyze the ad performance.
Call Extensions can be used together with Location Extensions. When these two features are used at the same time, the phone numbers displayed and the availability of click-to-call depend on the device where the ad is being viewed. To understand what to expect when using these features together, see What happens when I use both Call and Location Extensions?.
To learn how to enable these extensions, see How do I add a clickable phone number to my ad? and this (English only) video.
Available in the United States and United Kingdom on all devices. Available in all other Bing markets on smartphones only.
You can easily add an ad extension to multiple campaigns or ad groups with a few simple clicks.
