/The challenge

Doloris runs an immersive art experience in Tilburg and Utrecht. Ticket sales did not happen on their own site but in CM.com, and GA4, Meta and Google Ads all struggled to measure them.

CM.com offered limited settings and lacked what tracking needs, such as passing user-provided data. That left two open questions: how do you identify users across domains, and how do you handle consent when the purchase leaves your own domain?

/Our approach

Doloris already had a good relationship with CM, and CM was willing to work with us. That turned the project into two tracks.

First, consulting CM. We mapped their architecture, established that the datalayer and measurement implementation needed work, and handed them an extensive implementation guide. We tested along the way and gave feedback until it was ready.

Second, the implementation for Doloris itself: server-side tracking that keeps attribution intact even though the customer journey crosses into a vendor platform.

“We are very pleased with our collaboration with New North Digital. Their knowledge and expertise helped us make big improvements in our tracking.”
Kelly KluveMarketing manager at Doloris
/The outcome

After a period of monitoring and debugging, the GA4 setup is 98% accurate. With marketing channels attributed correctly, Doloris finally has reliable insight into the return on each channel.

We stayed on afterwards to keep on top of issues, so data quality holds and the team can focus on marketing instead of tracking.
