When creating a Call Extension, you choose where your number displays and how.
All devices (PCs, tablets and smartphones)
A provided forwarding number shows with your ads — you decide if it’s local or toll-free. Call tracking is activated with this option. You get specific tracking and analytics to monitor a range of call and campaign details — call type, duration and area code, for example. Richer customer insight can make optimising your campaign easier (available in U.S. and U.K. only).
Your own click-to-call phone number will display. Regular click reporting is available.
Calling your business is simple with any device. When making a call using a smartphone, customers click-to-call by tapping your number. On PCs and tablets, they can reach you via a free Skype call — a feature exclusive to Microsoft Advertising Call Extensions.
