Static call tracking in the realtor sector



Bauwerk Capital GmbH & Co. KG was founded in Munich in 2002 by Jürgen Schorn and Christoph Lemp. The owner-managed company is one of the leading project developers, consultants and marketeers of high-end properties in Munich, Berlin and Frankfurt.

Bauwerk Capital combines the fields of architecture, marketing and sales. With more than 40 permanent employees, the company supports the entire project process of a property – from the purchase of the land to project management, product development and design, positioning and sales.



With this comprehensive service portfolio, Bauwerk Capital acts on the one hand as an investor and developer, and on the other as a joint venture partner or service provider for property owners, investors, real estate developers or property developers.

In the past five years Bauwerk Capital has completed more than 20 projects. Since 2010, it has successfully positioned almost 1,000 new-build apartments, with a sales volume of around a billion euros. As a modern property service provider, Bauwerk Capital, at its headquarters in Munich, is therefore a market leader in the field of high-end, new-build apartments. The company also has offices in Berlin and Frankfurt.

Bauwerk Capital is aware of the extent of its corporate social responsibility when designing living spaces. The company is actively involved in the German Sustainable Building Council and has received countless awards, including the Brand Award of the real estate sector and the red dot design award.

“How do we link incoming calls to our various communications activities?”

“How can we see if our campaigns are generating call leads?”

The customer’s challenge is easy to describe: How can calls, which are still among the most valuable leads, be evaluated in such a way that a meaningful evaluation is possible? In addition to calls via channels such as AdWords campaigns, offline campaigns (brochures, ads, etc.) should also be measured.

The customer’s job is also to make all this available in a way that is both efficient and compliant with data protection regulations.


  • Different dynamic call tracking numbers
  • Single numbers for print campaigns
  • Integration of Google Analytics
  • Campaign management

Individual call tracking number pools are activated for the various projects in different cities. With the integration of Google Analytics, it is now possible to obtain important information about the origin of inbound calls.

The use of individual telephone numbers in print campaigns in combination with the campaign management system enables a performance analysis of individual advertisements and print materials.






On our website in particular, it is extremely important to note two things. Firstly, visitors to our website ideally want to see regional, project-related telephone numbers. This strengthens trust in our offering and increases the number of calls compared to calls made to a national service number.
In addition, in order to be able to guarantee that our marketing budget is played out in a performance-oriented manner, we must obtain information about the origin of the call as well as about the complete customer journey. We are able to do this by using dynamic call tracking in combination with regional telephone number pools.



Just as with the use of dynamic call tracking numbers on the website, we also need a means of monitoring the success of our print campaigns. How many calls did we receive due to which ad? Which exposé was most successful in the end? By using regional single numbers together with matelso campaign management, we are now also able to optimize our “offline” campaigns in terms of ROI and CPL.



At the end of the day, we therefore have a quick overview of our effectiveness in the individual channels – in the marketing tool of our choice. We have different sites in Germany at which we use flexible landline numbers and can therefore produce an accurate, location-specific evaluation.

Summary: It’s the perfect solution to combining the offline telephone world with the online world.
