Google launched call-only campaigns in February, and in June made them the exclusive way to display only your phone number in ads on mobile devices.

The intended idea behind call-only campaigns is great: Pay Google only when someone actually calls your business. But is that really how call-only campaigns work?

We wanted to see what our advertisers’ actual cost-per-call was from their call-only campaigns, so we compiled call-only campaign data from across a number of the client accounts we manage.

We compared the number of clicks from call-only campaigns to the number of phone calls Google tracked from each campaign. Our date range was May 1 through July 31, 2015.

Our finding: There were 18% more clicks than calls from call-only campaigns.

That data is based on nearly 25,000 calls received across a wide range of client accounts.

This means that our advertisers’ actual average cost per call during that date range was 18% higher than the figure we’d reach if we were defining each call-only campaign click as a real-life phone call.

What could cause this discrepancy? It comes down to the mechanics of how call-only ads work.

When you tap a call-only ad on your phone you are not instantly making a phone call. Your phone will show you your calling screen, with the advertiser’s phone number entered, and you must tap again to make a call. It’s probably between those two steps that we’re seeing most of that 18% discrepancy.

There are several reasons someone may not finish making a call.

  • They want to visit a website, not make a phone call
  • They tapped the ad accidentally
  • They change their mind

It would be wise to carefully monitor the call-to-click ratio in call-only campaigns and look for abnormal discrepancies. Significant discrepancies may point to scenarios where most users want to visit the website to get more information before calling, or other issues.
