Your journey to mastering Google Tag Manager

Google Tag Manager is not a simple tool. Even though you can get started in a couple of hours, getting a proper introduction and then digging deeper into the nuances will require a lot of your time (most likely years), especially if you try to do that on your own.

I have taken the long path of “learning by myself” and have spent way too much time. I still think to this day that if I had taken some GTM courses, this whole learning journey would have been much faster and more efficient. So, if you want to avoid my mistakes and progress much faster, I have a solution.

If you are an avid GTM user who wants to take a shortcut to master the tool sooner, this course bundle is exactly what you need.

For those who want to prepare for the future of web analytics

Over the last several years, our industry has drastically changed (e.g., Apple’s ITP, privacy regulations, the launch of Google Analytics 4, server-side tagging, etc.). And things are not slowing down.

Don’t be left behind. Stay sharp and up-to-date.

The courses in this bundle are updated to reflect those changes:

  • Unlock Google Tag Manager’s potential by using powerful features
  • Learn how to work and benefit from server-side tagging
  • Learn how to enrich data and increase your ROI from paid ad campaigns
  • Learn how to write JavaScript and use it in your setups

Want to have step-by-step examples on how to implement advanced features? Julius won’t disappoint you and guides you all the way. Brilliant teacher, five stars!”

❝When it comes to GTM and GA4, Julius is one of the "go-to" figures in the analytics space❞

This Bundle includes

Three Premium Courses

You will get instant access to the learning materials of three courses:

  • Intermediate/Advanced Google Tag Manager course
  • First-party Data Masterclass
  • JavaScript for Google Tag Manager

I have spent 1000s of hours working with GTM. I have polished workflows, processes, etc., and now you can get my knowledge through these courses.

When I am hired on a project, I charge $300/hour. Having that in mind, the value of my courses is a no-brainer.

Bite-sized video lessons + bonus modules

Shorter videos (rather than having several 1-hour long) enable you to learn things more gradually and stay more motivated as you keep seeing your growing progress.

Sandbox website & practical knowledge

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.

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.

Support from the instructor

Got stuck? Have some questions? Feel free to ask in the private community. Also, you are free to post questions/comments under each video lesson.

30-day money back guarantee

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

Regularly updated, highly recommended

“Any time anybody at Northwoods wants to learn GTM, we run them through Analytics Mania’s courses. One of the wonderful things is that Julius continues to keep them updated.” – Fred Pike, Northwoods

Is this bundle right for you?

Both courses in the bundle are designed for digital marketers and analysts who want to get more control over their website tracking.  After completing both courses, you will become a Google Tag Manager expert who is capable of solving complex web tracking challenges.

This bundle is right for you:

  • if you consider yourself an intermediate GTM user
  • if you want to have more flexibility/power while managing tracking codes
  • if you want to properly implement GA4 Ecommerce Tracking
  • if you don’t want to spend months trying to figure out things on your own
  • if you like to learn things by actually doing practical tasks
  • if you want to be prepared for the future of web analytics

This course is not for you if:

  • You are completely new to Google Tag Manager. You must have proper fundamentals before taking this bundle.
  • 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 technical topics (like JavaScript, HTML, CSS selectors, etc.)
  • You think that GTM can/should 100% replace developers in your projects. You will learn how to significantly reduce dependency on developers, but you CANNOT avoid them 100%.

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

About JavaScript for GTM course:

“5-stars would be an understatement of how great this course is! The real-life practical examples are super helpful in applying what you just learned right away to small projects. You don’t have to finish the entire course before you can reap any benefits. Julius’s ability to explain abstract concepts with a true beginner’s perspective is uncanny. I have tried so many online JS courses for years, and none have ever explained things in a way people could understand like Julius does (and in far less time!). Well thought out, well-paced, and well structured–so worth it!”

– Valery Chen, Front-End Developer at The Frick Collection

About the Intermediate Google Tag Manager course:

We are a digital marketing firm that spends too much time creating reports for clients (or worse, not reporting on results). We needed to set up dashboards for clients that clearly demonstrate website conversions and other results from our campaigns. The Intermediate Google Tag Manager course from Analytics Mania provided fantastic in-depth training on how to collect and track the website data we need. The course is well organized and laid out clearly and provides a ton of helpful resources. Julius is easy to follow, explains concepts clearly, and is reachable through comments, the private community, and email. If you need richer data in Google Analytics, I urge you to take this course.

Frequently asked questions

They start right now! After enrollment, you will get immediate access to the entire content. Learn at your own pace.

Intermediate/Advanced GTM course contains 14 hours of video material (5 of them are about server-side tagging), JavaScript for GTM course is 14 hours long, and First-party Data Masterclass is around 8 hours. 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 a single course 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 3-4 weeks per course. But it is possible to do that even faster.

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 GA4 features (e.g. complete ecommerce setup)
  • You’ll have more confidence in crunching technical terms and cooperating with developers
  • The quality of your tracking setups will be much better
  • You will know how to conduct GTM audits (that can earn you quite a lot of money)
  • You will know how to configure and benefit from server-side tagging

Sounds like a good deal, right?

If none of the reasons above resonate with your company, let me know at [email protected]. I’m sure we can easily come up with something more personalized.

Yes, after you complete the courses, you’ll get certificates. Each course has a separate certificate.

How does lifetime access sound? After enrolling, you have unlimited access to both courses for as long as you like – across any and all devices you own.

To get the most out of these courses, it is highly recommended to be familiar with Google Analytics 4 basics (like event tracking), Facebook ads knowledge might be helpful in several lessons. You don’t have to possess any GTM knowledge to benefit from this bundle.

Speaking of other requirements, you should have a Google Chrome browser installed (because there are several plugins you’ll need to use during the course) and an internet connection, of course.

Then it means I didn’t do a good job teaching you! If you are unsatisfied with your purchase, contact me within the first 30 days (after the purchase) and I will give you a full refund. No questions asked.

Yes, all videos have English subtitles

No. Both courses provide access to sandbox websites where you will learn how to track particular interactions. If you have your own website, that’s also good. You can practice there.

However, server-side tagging lessons will require you to have some website and control of the domain (web address). Because of how it works, it’s impossible to give a sandbox website in those modules.

No, the price you see on this page is without the taxes, therefore, the final price might increase on the checkout page. But that depends on your geographical location.

Yes, you can. We accept payments with PayPal, Credit Cards, Apple pay, etc. You will see all options once you enter the checkout.

If you choose a monthly payment plan, you’ll need to complete a certain number of payments (it depends on the course/bundle). Once you make the first payment, you get instant access to all the content of the course/bundle.

When the next month comes, the course platform will automatically make another payment. Some banks might require you to approve the payment. In that case, you’ll receive an email about that with further instructions.

After all monthly payments are complete, you’ll keep lifetime access to course/bundle that you purchased.
