So your call to action is a phone call correct. This can be tracked by setting up an 800 number specific to the adwords campaign. The only way to find this number is from the landing page you have the ad going to. Then it is just looking at the number of calls from this number to see what kind of conversions you had from your adwords campaign. We have or use a time to determine if the call was a good one or not. Just a thought to help figure out if the ads are converting.
