AdWords Call Extensions are now eligible to be shown for mobile app ads. Since mobile apps are part of the Google Display Network, this marks the first time that phone calls can be generated from a display network targeted campaign. So make sure that any display campaigns opted into mobile devices have call extensions enabled.
From Inside Adwords:
“Call Extensions for in-app ads – We also recently introduced Call Extensions for ads showing in apps on the Google Display Network. Now in addition to click-to-call ads across the mobile web, advertisers can also drive calls from ads in more than 300,000 mobile apps.”
In addition, Google has also announced that call extensions are now available in Germany, and will be rolling out to even more countries soon.
