I have a campaign targeting handheld devices, and I use a phone extension for these ads with a dedicated phone #. I have been receiving a decent volume of calls, but I can't tell from what adgroup/keywords or what ads. Is there a way to track for what keywords a user clicked the phone extension link rather than the ad itself? From what I can see, a click on a the phone extension just gets registered as a normal click - but a phone call has much higher value to us than a click so I'd like to differentiate between the two if possible...
