Web Tracking Introduction

Web Tracking Introduction

In this short series, you’ll learn everything you need to understand the ins and outs of the modern tracking stack. From cookies and pixels to consent mode, UTM tags and server-side tracking.

Whether you're just getting started or want a clearer picture of how all the pieces fit together, this mini-course will help you make more concious, data-driven decisions without getting confused by the technical jargon.

Why web tracking is so important?

Analytics and ads tracking is the foundation of modern eCommerce and online business.

It tells you where your traffic comes from, how visitors behave on your site, and what drives conversions.

Without tracking, your ads can't optimize and you have very limited insight into what's working and what is not working.

With the right tracking setup, you can improve ad performance, increase ROI, and better serve your customers.

And why it is so complex?

The web tracking landscape has evolved rapidly recently. Privacy regulations like GDPR and CCPA have introduced strict rules around user data and consent

Browser changes (like Apple's Intelligent Tracking Prevention) restrict traditional tracking methods. At the same time tech stacks are increasingly complex: users move across multiple devices and platforms, making it harder to stitch together a clear customer journey.

All of this means that setting up accurate and reliable tracking is harder than ever.
