I am curious to know if anyone has been able to successfully track phone calls as a test objective with Google Optimize or whatever testing platform you may be using?
I am able to track web conversions in Optimize via a custom event I created using Tag Manager. However, I cannot figure out a way to include phone calls as a test objective.
The only solution I have found is to create a click-to-call event listener; however, this does not account for desktop users who may simply call the number directly on their phone without clicking on the actual tel: link.
Has anyone found a solution for measuring phone call performance within their testing platform? Fyi, I use tracking numbers with Dynamic Number Insertion on my site via What Converts (similar to CallRail).
Any insight is much appreciated!
