How do you connect a phone call back to the ad that caused it?

Session-based tracking numbers swap on page load, so each visitor sees a number tied to their session. When they call, the keyword, campaign, ad group, and device that brought them are attached to the call record, including calls from Google Ads call extensions.

Does attribution stop at the call, or does it reach revenue?

It reaches revenue. The call is scored, the booking outcome is captured, and both are written back to your CRM alongside the source. That closes the loop most marketing dashboards leave open at the click.

Will this fit the analytics stack we already use?

Call events fire into Google Analytics, and new Convirza calls show in HubSpot. The attribution lives in the tools your team already reports from.

What can we actually prove to a CFO with this?

Which channel drove the call, whether that call converted, and what it was worth. Because every call is scored and tied to its source, budget reallocation is grounded in booked outcomes rather than click volume.
