The assignment
Ziemi got introduced into the market during the summer of 2024. It’s a start-up, so they were still setting things up on their end. When we met them, their data wasn’t great and the paid ads set-up neither. We helped them by implementing server-side tracking, which improved their tracking drastically. Also, we improved their paid ads set-up in Google Ads and in Meta Ads in order for better results. The ROAS went up straightaway and the spend was kept under control. Find out what we did exactly and where we made impact.
This is what we did
We implemented server-side tracking for Ziemi which gave them back control over their own data. They were now independent of third-party data from for example Google and Meta. These changes were made to increase the data quality and also resolve the big difference between Google Analytics 4 data and Shopify Data. Also, we did a revamp of their paid ads set-up to increase the performance.
