What your data doesn’t show

There are three areas where your marketing is currently making decisions without data. Each of them is costing you money.

Call inquiries are your blind spot

Clicks, forms, downloads—everything is tracked accurately. But when it comes to phone calls, the trail goes cold. The phone rings, but your reports don’t show any campaign associated with it. Ironically, your strongest lead doesn’t show up in any statistics.

Your smart bidding learns from incomplete data

Google Ads optimizes based on what it sees. It doesn’t see phone calls. So the algorithm bids on form leads and, of all things, scales back the ad that actually makes your phone ring. Your best channel is shrinking—and looking at your numbers, it seems as though the ad is to blame.

They count calls, but don’t know their value

Sounds like a good day. But hidden among those calls are appointment requests, complaints, job applications, and the supplier who dialed the wrong number. As long as every call counts the same, your campaigns are optimized for a conversion that might not even have been one.

What is call tracking—and how does it work?

Call tracking assigns phone calls to a specific marketing source. Campaigns, ads, or individual website visitors are assigned their own phone numbers—making it possible to determine which channel triggered the call.

Online, you can see which ad or keyword led to the call—with the same level of detail as for clicks. Offline, you use dedicated phone numbers on posters or flyers to identify which channel is effective.

Call conversions are automatically reported back to Google Ads, and call details are fed into GA4 and your CRM. This lets you identify the true value of every call—whether it came from a search or a poster. The Call Tracking Use Cases show how this works in your industry.

Frequently asked questions about Call Tracking

matelso Call Tracking is an innovative technology that enables marketers to place even greater trust in the performance of their campaigns and to further optimize them based on customer needs and habits. Here, interested parties can find answers to the most important questions about our MarTech solution.

Call Tracking is a method that attributes phone calls to a specific marketing source. To do this, campaigns, ads, or individual website visitors are assigned their own phone numbers. When someone calls, it’s possible to determine which channel, ad, or keyword triggered the call—the call becomes measurable as a conversion, just like a click or a form submission. The goal: to determine which advertising measures are effective and which are not.

Call Tracking gives companies the ability to accurately measure and optimize the effectiveness of their marketing efforts. It enables a detailed analysis of call sources and call histories and helps improve customer service.

Call Tracking provides a better understanding of which campaigns generate the most calls and which initiatives have the highest conversion rates. By analyzing call times and durations, marketers can also gain valuable insights into customer needs and behaviors.

In general, Call Tracking links an advertising campaign to a specific phone number and the calls it generates. The technology tracks and analyzes how many calls individual advertising campaigns actually generate and, ultimately, how successful they are. In particular, call tracking focuses on call duration, call counting, and determining the value of a call.

In addition, call tracking can be divided into two different levels, which work as follows:

• Static Call Tracking
• Static Call Tracking uses different phone numbers for the website, print ads, and radio to measure the performance of these media. Specifically, this method assigns a single phone number to each (advertising) campaign. This allows marketers to determine, for example, which billboard or website generates the most calls.

• Dynamic Call Tracking
• Dynamic Call Tracking enables the precise measurement of the success of online advertising campaigns. Here’s how it works: A script is embedded on a website that assigns a unique phone number to each visitor. This allows marketers to unambiguously attribute every call generated to a specific website visitor. It also allows them to measure the correlation between phone inquiries/orders and the individual online advertising channels (SEA, display, newsletters, SEO, etc.).

matelso Call Tracking is GDPR-compliant. We act as a data processor on behalf of our clients and use only first-party cookies. The data collected as part of our projects “belongs” to our clients and is not used by matelso for any other purposes. Additionally, our servers are located in Germany.

For dynamic call tracking, the website’s privacy policy should include a corresponding notice. Furthermore, call tracking should be integrated into the consent management system. We’re happy to assist with the review—in collaboration with data protection officers and legal advisors.

Yes. matelso Call Tracking can be connected to numerous marketing, analytics, and CRM systems—including Google Analytics 4 (GA4), Google Ads, Matomo, Salesforce, HubSpot, Microsoft Advertising, and Zapier. Call tracking data can also be transferred to other systems via APIs and custom integrations.

Through integration with GA4 and Google Ads, calls are recorded as measurable conversions and attributed to their original campaign, ad, or even the triggering keyword. This ensures that phone leads are also included in campaign analysis.

Particularly relevant for Google Ads: Qualified calls and their conversion values can be fed back to Google Ads. This provides Smart Bidding with additional conversion data and enables it to optimize campaigns specifically for ads and keywords that actually generate valuable calls and leads.

Each customer is free to choose whether to use a local access number. For each Call Tracking scenario, you can specify whether you want a local Call Tracking number or an 0800 number. The range of features is the same. Experience shows that local businesses often prefer a phone number with a local area code.

There is no “one-size-fits-all” solution for call tracking—every package should be customized. We’d be happy to consult with you over the phone and put together what we believe is the perfect call-tracking package for you, with no obligation.

Static Call Tracking uses fixed phone numbers for each channel or medium. This allows you to see whether a billboard, ad, or TV commercial generated calls. Dynamic Call Tracking automatically assigns a unique phone number to each website visitor. This makes it possible to determine which ad, keyword, or landing page triggered the call. In practice, most companies combine both methods.
