Have you been using GTM for a while but still get stuck way too often?

Google Tag Manager is not an easy tool. Of course, you can launch a bunch of basic tracking codes and be happy about it. But if you want to do more serious and quality implementations, a lot of new obstacles come in your way.

Do any of these struggles sound familiar to you?

  • You have configured GA cross-domain tracking but it does not work
  • You are not sure how to properly test it
  • iFrame tracking isn’t working
  • GA Enhanced Ecommerce setup looks like a nightmare to you and you have no idea where to start
  • You have implemented Enhanced Ecommerce but a lot of data is missing
  • It’s very difficult to cooperate with developers (and to be on the same page)
  • You feel like you could do more on your own but just don’t have enough technical knowledge
  • You feel like you don’t uncover GTM’s potential

I’ve been there! I know what it means to be in all these situations and to get stuck. To solve this, I chose the hard and the long way – figured them out on my own (and this took years). With this course, you can learn to solve your web tracking problems much faster.

Become a Google Tag Manager professional

A true professional knows his/her tools well and can offer solutions for complex tag management problems. And this course can help you reach this point much sooner. But why limit yourself? Additionally, you, as GTM specialist, will be able to:

  • Speed-up tracking implementations/updates, make them easier to scale
  • Communicate with developers easier and more efficiently
  • Build a solid testing practice that prevents expensive mistakes
  • Create internal workflows in your company that make data control easier to handle
  • Feel more confident with technical terms (if you don’t consider yourself technical yet)

Take your website tracking skills to the next level by unleashing the power of Google Tag Manager. Learn how to solve complex web tracking problems, confidently deal with technical issues, perform high-quality testing, smoothly cooperate with developers, and so much more.

This is a fantastic course if you want to take your GTM skills to the next level. Being stuck after implementing the pageview tag and basic Event Tracking?

What can you expect from this course?

8 modules + a bonus module

More than 50 videos explaining the inner depths of Google Tag Manager. The duration of the main course material (intermediate + some advanced topics) is 11 hours. Bonus module consists of lessons that did not fit into the main modules (but are still quite useful)

Dedicated GA Enhanced Ecommerce module

1 out of 8 main modules of this course is dedicated just to the implementation of Google Analytics Enhanced Ecommerce via Google Tag Manager. It’s impossible to properly learn this topic just from a single 20-minute video. There are many nuances that you need to be aware of. Length of the module: 2 hours.

Practical tasks and sandbox website

This course is not just “sit back and watch”. The best way to learn is to do, therefore, you will have to complete practical tasks on an actual website (you can use either your own site or a sandbox website provided on this course).

Quick quizzes

At the end of every module, there is a quick quiz to check what you have learned. It’s a great way to ensure that you have gained the most out of lessons.

Useful resources

You’ll get access to my checklists and other downloadables that will help you be more efficient with Google Tag Manager. I personally use them on various projects.

Lifetime access to the course + Free Updates

Your Google Tag Manager course purchase includes lifetime access to the training materials. If you want to revisit a particular topic of the course, you can come back here anytime. Once the course gets an update (e.g. a new lesson or re-recorded module), you’ll get that instantly, free of charge.

30-day money back guarantee

If you complete this Google Tag Manager course and don’t feel like you’ve reached the next level of Google Tag Manager, email me for a refund. No questions asked.

But don't take my word for it

Nick Groh (from Miles Technologies) is one of the students who has already taken this Intermediate Google Tag Manager course. Listen to what he has to say.

Is this Google Tag Manager course right for you?

This course is designed for those who consider themselves as intermediate Google Tag Manager users and want to learn more. If you’re already familiar with basic concepts as tags, triggers, variables, data layer, how to use the preview and debug mode, how to track standard interactions and conversions, this course is just what you need (because we’ll dive much deeper).

This course is right for you if:

  • You’ve been using Google Tag Manager regularly at least for the last 3-6 months. It is recommended for you to have completed my GTM for Beginners course (or something of a similar level).
  • You’re not afraid of becoming a technical marketer (because we’ll also cover such topics as HTML, CSS, DOM, Regular Expressions, cookies).
  • Consider GA Enhanced Ecommerce implementation via GTM to be a real headache
  • You want to be sure that your tracking implementation is solid and tested
  • You feel that you do not know Google Tag Manager’s full potential

This course is not for you if:

  • You want to learn how to track mobile apps or AMPs (accelerated mobile pages). This course explains only regular website tracking techniques
  • You are afraid of “getting your hands dirty” with HTML, CSS, DOM, Regular Expressions, etc.
  • You think that GTM can/should 100% replace developers in your projects.
  • You don’t know Google Tag Manager fundamentals well. P.S. My GTM for Beginners course is the perfect first step before taking this intermediate/advanced course.
  • You expect to learn JavaScript here. Even though we will be definitely using JS code snippets, they will be ready-made. There is still a lot for you to learn in GTM, even without JavaScript.

This course is on-demand. You can learn at your own pace and apply new knowledge on your own GTM account.

Let’s have a really quick reminder of what Google Tag Manager is and how does it work. That way, we’ll all be on the same page and ready to proceed. Topics covered:

  • What is GTM?
  • What are tags, triggers, variables?

Module 3: An in-depth look at variables in Google Tag Manager

Beginners are already familiar with the most common GTM variables (e.g. Page URL, Click Class, GA Settings Variable, Data Layer Variable, etc.). However, the true GTM power lies within other, less popular variables. Topics covered (but not limited to):

Frequently asked questions

When does the course start and finish?

This intermediate Google Tag Manager course starts right now! After enrollment, you will get immediate access to the entire content of the course. Learn at your own pace.

How long does it take to complete the course?

The main course material consists of 11 hours long video material. Speaking of the completion time, it very much depends on how much do you plan to spend on it every week. Some students have completed it over two weeks, some spent a couple of months (or more) due to their busy work schedule. In my opinion, the most optimal schedule should be 4 weeks.

How do I convince my boss to sponsor me?

In many cases, employers pay for the course. Here are some thoughts:

  • Your team will become agiler as they will be able to launch new tracking campaigns faster
  • You will be able to solve much more complex situations
  • Not only will you get more familiar with GTM functionality, but you’ll also get a closer look at advanced GA features (if if you haven’t touched them before)
