Workshops on advanced digital analytics: BigQuery, cookieless tracking, consent, attribution, and building data warehouses for reporting and activation.
This year, I led several workshops at digital and media agencies. The scenario was usually similar: at some community data/analytics event (or more often at the afterparty), I'd connect with the team leader of their analytics department and we'd arrange a workshop aimed at helping their internal team level up. The goal was to share not only current technical know-how and best practices, but also how to demonstrate the value of digital analytics to clients and which measurement use cases deliver the greatest real-world impact.
I usually do these workshops for free. I believe it's healthy not to see everything through the lens of money - to simply enjoy sharing what I'm personally passionate about and helping others pursue a similar path. The few hours a workshop takes do cost me some time, but rather than agonize over pricing and approvals, I prefer not to deal with it at all.
My reward is mainly the genuine interest in digital analytics I see among the young people on these teams. Let's be honest, most of them are about ten years younger than me, already working in analytics at some level, and they sense there's plenty of room to grow. I want to help them get there.
There's a significant difference between being able to deploy GA4 via GTM and report last-click performance to a lead, and building a clear data model for all of a client's marketing and frontend data, bringing order to their data ecosystem, connecting it with their CRM, and stitching together the entire story from ad banner impression to customer acquisition. And beyond just reporting that data also activating it in communication. All while explaining it to the client in a way that gets everyone pulling in the same direction, with a clear strategy, goal, and delivery.
This year, I ran workshops at Ogilvy, at Publicis with Filip Stavárek's team, and at Fragile with Filip Vlasák's team. The topics we covered related to advanced digital analytics for larger clients.
Here are some of the topics we discussed:
👉 How and for which use cases to leverage BigQuery and server-side measurement in practice, and how to report session and event sources in BigQuery. Tip: we currently pull session sources from the params of the session_start event.
👉 Consent and cookieless tracking - how to build cookieless tracking in practice, what it looks like, and what kind of data it provides. Tip: for cookieless tracking today, we most commonly use the Stape Data Tag on the frontend, which elegantly creates an anonymous event from datalayer parameters (without setting any storage), sends it to sGTM, and writes it directly to BigQuery.
👉 Whether attribution can be applied to non-consented data (yes, it can) and how to do it using what's called an entrance event.
👉 How to build a marketing data warehouse in BigQuery not just for reporting, but also for data activation in media systems, personalization, email marketing, and more. Examples of feeding Google Ads from BigQuery via direct integration, along with client experiences.
Beyond the purely technical topics, we discussed which analytics use cases and services make sense, how to establish and sustain a quality analytics team within a large agency, and how to use analytics to deliver real value that clients are willing to pay for.
I'm rooting for all the teams I trained this year and I'm confident that what we covered will soon be put into practice!

He enjoys combining web development, automation, and data work to create solutions that make sense both from the user’s perspective and in terms of the technical foundations behind them. What he finds most rewarding is turning a more complex problem into a clean and reliable solution.
Jiří Otipka
Analyst
Jirka has been working in marketing for over 10 years, and if there is anything he enjoys more than numbers themselves, it is connecting them. He loves mathematics and data analytics, and thanks to his interest in exploring source code, he can easily communicate with developers in their own language. At MeasureDesign, he specializes in connecting new data sources - building custom connectors in Python, testing data quality, and exploring which data combinations make the most sense from a business perspective. He is completely at home in Looker Studio and also has extensive experience evaluating PPC campaign performance.
Lenka Pittnerová
Analyst
Lenka joined MeasureDesign at the end of 2025, bringing extensive experience from PPC marketing, where she spent many years working with Google Ads, Meta Ads, and other advertising platforms. While managing campaigns, she repeatedly ran into the same issue - poorly set up or insufficient web analytics, which made effective optimization nearly impossible. This challenge initially led her to analytics out of necessity, but over time she discovered that she enjoyed it even more than advertising itself. Today, she focuses primarily on implementing web analytics and data solutions that provide companies with high-quality, reliable data for strategic decision-making and performance marketing. She continues to work on selected PPC projects as well - not only because she still enjoys them, but mainly to stay closely connected to the reality of media platforms and the real needs of clients.

Anna Horáková
Analyst
Anička has over 7 years of experience in the agency world, where she has managed social media ad campaigns for clients, and especially for content-driven websites, her favorite. Wanting to broaden her perspective beyond campaign data, she gradually shifted her focus toward web analytics. She joined our team in 2022 and now specializes in data analytics, using GA4, BigQuery, Looker Studio, and other tools to connect and dig deeper into data — delivering insightful analyses and valuable input for business decisions.

Zuzana Mikyšková
Analyst & Co-Founder
Zuzka's career path led her through corporate innovation and research management, running word-of-mouth projects, and later to a digital agency, where she managed website development projects. However, Zuzka is naturally curious and wanted to understand how a website actually works once it is launched into the world. That curiosity led her to study web analytics — and eventually to a key collaboration with Vašek. In 2019, they founded the company together.
Vašek Jelen
Lead Analyst & Co-Founder
Vašek has been working in digital analytics for over 15 years — from setting up tracking to data storage, visualization, and interpretation. He helps companies keep their data in order and make full use of it. He focuses primarily on data from digital platforms such as websites, apps, and client zones, and on connecting that data with other business data like media and customer data. After years of freelancing, he co-founded the analytics studio MeasureDesign, where, in addition to working on analytics projects and bespoke training sessions, he also mentors and educates new analysts.
Blanka Hejduková
Back Office
Blanka joined our team in 2024 and has been responsible for back-office operations, including invoicing and administrative tasks, ever since. She draws on her experience from the Czech Post and her background in financial management to keep everything running smoothly. In her free time, she enjoys traveling with her two children and finds relaxation in working in her garden.
Markéta Svěráková
Analyst
Markéta started out in marketing, but then came maternity leave — and with it, total chaos. In an effort to hold on to the last bits of sanity, she turned to data. After all, numbers don’t yell, spill cereal into your keyboard, and at least they make some sense. She completed a data analytics course at Engeto Academy, where she bonded with SQL, Power BI, Excel, and Python, and started looking for patterns outside the bounds of children’s coloring books. Today, at MeasureDesign, she helps clients understand what their numbers are really saying.
Petra Súkeníková
Analyst
She joined MeasureDesign in 2023, specialising in measurement implementation and reporting. Her favourite moment is when, after all the setup and testing, the first data finally starts flowing in. Her biggest challenge? The unexpected (and often undocumented) changes from Google – those are the times when every analyst turns into a paranormal behaviour expert. 👻 She was a member of our team until summer 2026.
Klára Belzová
Analyst
Klára has been with the company since 2019. She focuses mainly on web analytics but is not afraid to dive into data work in BigQuery. What she enjoys most is guiding clients through the entire process — from defining their needs to implementing tracking and creating the final data visualizations.
She gets an almost suspicious amount of joy from a clean and well-organized GTM container or a report full of useful data.
