Welcome to our blog post, where we delve into the intricacies of mastering Google Tag Manager (GTM). This powerful tool can revolutionise your website’s marketing capabilities, but it comes with its own set of challenges. Let’s explore the common mistakes users make and how to avoid them!

Mastering Google Tag Manager: Avoid These Common Mistakes

Google Tag Manager (GTM) is a powerful free tool that allows you to easily manage and deploy marketing tags (snippets of code) on your website without having to modify the code. While GTM can significantly streamline your workflow and enhance your data tracking capabilities, mastering it can be quite challenging. Many users face numerous issues, from setting up tags and triggers to ensuring everything works seamlessly.
If you’ve spent hours setting up GTM only to find that something isn’t working as expected, you’re not alone. 

In this article, we will go over the most common Google Tag Manager mistakes and how you can avoid them:

  1. Neglecting the GA4 DebugView
  2. Ignoring Audits and Lack of Ownership
  3. The All in One Deployment
  4. Neglecting Developer Collaboration

1. Neglecting the GA4 DebugView: A Critical Oversight in Your GTM Setup

One of the biggest rookie mistakes in Google Tag Manager is skipping the GA4 DebugView check after setting up Google Analytics 4 tracking. Many beginners assume their job is done as soon as the GA4 tag fires in the Preview and Debug console. But here’s the truth: that’s just the beginning.

Imagine you’ve done all the hard work, only to find out later that your data is being sent to the wrong Google Analytics 4 property, or worse, not being recorded at all. This is why the DebugView is crucial. It allows you to see the real-time flow of data, ensuring everything is tracked accurately.

Additional tip: There are other tools like Facebook Pixel that also offer real-time debugging features. Always take advantage of these to ensure your tracking is spot-on. In the world of data analytics, it’s always better to be safe than sorry!

Transitioning from the importance of DebugView, let’s consider another crucial aspect of GTM management: maintaining organised and efficient audits.

2. Ignoring Audits and Lack of Ownership: A Recipe for GTM Chaos

When multiple people have access to a Google Tag Manager container, it can quickly turn into chaos. Picture this: an agency contractor adds marketing tags, a colleague from the IT department adds tags for a new feature, and no one is coordinating these changes. It’s a recipe for a disaster, with everyone doing their own thing without knowing what others are up to.

This lack of coordination leads to a container full of tags that might conflict with each other. Even worse, some of these tags could be outdated and slow down your page speed (since every extra tag can slow down your page).

How do you avoid this? Regular audits are key. Aim to review your container every 6-12 months, working with your team to ensure all tags are up-to-date and necessary. You’d be surprised how many Google Tag Manager containers have tags for tools that haven’t been used in years.

Even better, assign one person or a team to be in charge of Google Tag Manager management. This way, all changes go through them, ensuring they make sense and won’t cause problems. By having this control, you can keep your GTM container organised and running smoothly.

Next, let’s discuss a strategic approach to deploying changes in GTM to minimise risks.

3. The All in One Deployment: Why Publishing All Changes at Once is a Risky Move

If you often bundle up all your new tracking features and release them at once, this strategy can spell trouble for you in the future.

It is because if something breaks in your latest version, you’ll have to take everything back all together, including the parts that were functioning perfectly. Worse yet, pinpointing the exact issue can be like finding a needle in a haystack, forcing you to start over.

A smarter approach is to follow the one feature, one version rule. Publish each new feature as its own container version after confirming it works properly in Preview and Debug mode. This way, if something goes wrong, only the latest change needs attention, and your previous updates remain intact and operational.

Following the deployment strategy, it’s essential to emphasise the value of developer collaboration for a seamless Google Tag Manager experience.

4. Neglecting Developer Collaboration: The Recipe for GTM Headaches

Many marketers want to jump into Google Tag Manager, hoping to bypass their developers’ input entirely. But here’s the hard truth: developers are still your best friends and you will really need their help for complex setups.

Ignoring developer input can result in losing the ability to publish GTM container changes, causing you only headaches and project delays.

Building a strong relationship with your developers isn’t just smart—it’s essential. They can help you create a more reliable and powerful tracking system. Plus, working together can lead to a more harmonious and effective team environment.

Lastly, let’s look at an often-overlooked aspect of GTM usage: monitoring page performance after adding tags.

5. Additional Tip!
Overlooking Page Performance After Adding Tags: A Costly Mistake

Every additional tag, whether it’s Facebook Pixel, GA4, Reddit Pixel, Quora Pixel, or LinkedIn Insight Tag, they all increase your page load time. If you stack them up without monitoring, you might end up with a very slow performing site.

To avoid this, it’s essential to monitor your page speed after each new tag is added. Run tests before and after implementing new tracking codes to see the impact. There are many tools available online, like Google PageSpeed Insights, that can help you with this.

Regularly checking your page performance ensures that your site remains fast and efficient, providing a better user experience and maintaining your SEO rankings. Remember, a faster site keeps both users and search engines happy!

Conclusion: Elevate Your GTM Game by Avoiding Common Pitfalls

By paying attention to these key areas and avoiding these common mistakes, you can harness the full potential of Google Tag Manager. It’s not just about setting up tags and triggers; it’s about creating a cohesive, efficient, and effective tracking strategy that supports your marketing goals. Keep learning, stay vigilant, and always prioritise accuracy and collaboration in your GTM endeavors.
This approach will help you become a true master of Google Tag Manager, driving better insights and results for your business!
