Invoca has introduced a new way for marketers to connect Google Ads with actual customer calls—even as privacy rules tighten and cookie tracking gets murky. The company’s durable attribution solution, built with Google, is aimed at advertisers who need better clarity on which ads are driving real revenue.
This release is part of Invoca’s call tracking platform, which already includes AI-based tools that analyze the content of phone calls to measure intent and outcomes. But this time, the focus is on fixing a growing problem: ad clicks that lead to calls, but with no reliable data to track where those calls came from.
Why Phone Leads Are Getting Harder to Track
As browser privacy features continue to limit third-party tracking, marketers have seen fewer clear signals connecting ad spend to actual conversions. This is especially true for calls—still a major source of leads in fields like healthcare, home services, and financial services.
Invoca’s durable attribution solves this by using a mix of Google identifiers—such as GCLIDs, GBRAIDs, and WBRAIDs—and enhanced conversions. Even when some data is stripped during privacy-focused browsing, Invoca still links phone calls to ad campaigns. This lets marketers show their impact and fine-tune where budgets go.
Connecting Ads to Calls—Even Across Devices
Many consumers start their path to purchase on one device and finish on another. Some watch a video, read a review, and call a business days later. Invoca’s new attribution method captures this trail. Marketers get a full view of how different ads—Search, YouTube, Display—play a role in getting a prospect to call.
The tool also feeds that data directly back into Google Ads Data Manager, allowing advertisers to sync performance data quickly without heavy tech overhead.
Brands See Measurable Gains
Companies across several industries are already using the new tool—and speaking out about the results.
Automotive: Christian Brothers Automotive now attributes all phone-based revenue to the source that brought it in. This helps them shift budget where it works and improve return on investment.
Finance: At MoneySolver, Invoca helped the team increase ROAS by 30%. Marketers say Google Ads now knows exactly which phone leads matter, because Invoca sends back reliable data.
Healthcare: Nemours Children’s Health found that without tracking phone calls, ROI reports didn’t tell the whole story. Invoca fixed that. Now they tie ads to patient revenue and use those numbers in boardroom conversations.
Home Services: Renewal by Andersen has saved tens of thousands of dollars on marketing by cutting waste and leaning into what performs. Invoca’s attribution made the difference.
No-Code Setup and AI Extras
Invoca’s platform also includes built-in integrations with tools like GA4, Google Marketing Platform, and Adobe Experience Platform. That means the data isn’t siloed. It feeds directly into broader campaign analytics. The company also uses AI to listen to calls and spot patterns—such as which ad language leads to more bookings.
Marketers don’t need to write custom code or hire outside developers. Everything connects through point-and-click interfaces.
Where This is Going
The advertising landscape isn’t getting easier. Privacy rules are growing stronger. Cookies are fading. But business leaders still want to know if ad budgets are pulling their weight.
Invoca’s durable attribution brings much-needed clarity to one of the oldest lead sources out there: the phone call. By tracking what ad led to what call—and what that caller did—Invoca helps marketers make the case for budget, prove their worth, and cut what doesn’t work.
The tool works across Google’s Search, Shopping, Display, and YouTube networks and gives advertisers a way to measure full-funnel performance—even when browser limits block traditional tracking.
