Hey, I’m Julius Fedorovicius
I founded Analytics Mania in late 2016. Since then, the blog has grown strong and continues to serve hundreds of thousands of marketers and analysts. Here I share my knowledge, experiments, and learnings related to web analytics, mainly Google Tag Manager and Google Analytics.
I also run the Google Analytics 4 and Google Tag Manager communities on Facebook where awesome people from around the world help each other.
Last but not least, I actively help others to learn Google Tag Manager and Google Analytics with my GTM/GA online courses.
