MeasureCamp Brno 2025

On September 6, another edition of MeasureCamp - our favorite community event - took place at Brno’s Gen. We were thrilled to see that 74 women attended this year’s MeasureCamp (5.4% of them from our team 🙂), and it’s clear that the number of women in data and analytics continues to grow 🚀.
We didn’t want to show up empty-handed, so we prepared two talks. Zuzka shared her experience from dozens of server-side tracking implementations, and Vašek focused on the legality of Advanced Consent Mode and our own solution for compliant measurement without consent.
To wrap things up, the women from our team also hosted a “Women in Analytics” therapy session, which we’ll write more about next time 😉.
Zuzka Mikyšková – Server-side is the new black!
Last year was all about consent. And while consent is still making every implementation more complicated, this year another topic has taken center stage: server-side tracking.
Why do we love it? Because it gives us back control over what happens to the data. Whatever we send through server-side GTM, we can check, transform, or even drop- before the data ever reaches Google Analytics, Facebook, or any other tool.
🔹 Architecture: A single server-side GTM can handle multiple websites (lower costs). More sGTMs only make sense for completely separate projects.
🔹 Cost: For websites with about 300,000 - 12 million GA hits per month, minimum 1-2 instances are enough, which comes to roughly 4,000 CZK/month.
🔹 Data Tag instead of GA hit: Core tracking runs through GA, but anything extra -including anonymous measurement - is better sent via the Data Tag.
Here’s a short video of the closing applause :)
Vašek Jelen – Legal Tracking Without Consent
In his talk, Vašek covered the following points:
🔸 Even within the current legislation, it’s possible to legally track a lot of data in analytics and media systems without consent - helping to fill in the gaps left by cookie banners.
🔸 With the right technical setup (most often cookieless frontend + sGTM + BigQuery), you can combine consented and non-consented data and get much closer to reality. (I also shared a public dashboard built on BigQuery to show what such a report looks like.)
🔸 Advanced Consent Mode, used by Google, is a gray area + the risks of relying on this technology.
🔸 It’s possible to send conversions to Facebook even without user consent - using a random fbp cookie + fbc from the URL + IP anonymization on the server. (Of course, legal approval is required in this case!)
🔸 How we’ve built our own anonymous analytics tracking in the Google stack, along with a public repository (GTM .json) available for download.
🔸 How we leverage the Google Ads export to BigQuery in this context - and why everyone should enable it.
Since MeasureCamp was such a great event, we’d like to give a big thank you to the organizing team for all the energy they put into making it happen. This year, we also joined as one of the sponsors, and it feels good to have contributed in this way. The whole event was a success - including the afterparty at Schrott and later at Bar, který neexistuje 😎.
See you next year at MeasureCamp Prague!
