One of the recurring problems in migrating to Google Tag Manager is how to make the transition as smooth as possible. Usually it requires that we agree with the developers on a time when the old code is removed, and at that moment we need to make sure the GTM tags point to the right UA code. This is, of course, only one use case for migrations, as some people do the entire migration in a staging environment, and some just don’t care if they lose a little bit of data along the way.

When our good friends in the Google Tag Manager developer team first introduced the Lookup Table Macro, we were excited. For many of us, it soon became the weapon of choice especially when used as a management and optimization tool for the container itself. However, the macro wasn’t considered perfect. In fact, the most frequently heard request had to do with the core functionality of the feature itself: the macro should support operations, that is, predicate logic. Read More…

If you use Google Analytics, Google Tag Manager, or any JavaScript-based data collection or analytics platform, have you ever stopped to wonder how they actually work? I mean, you obviously care about getting the data in, but are you taking the machinations of these tools for granted? This is something I’ve been thinking about for a long while, because I’m not so sure that many who work with these platforms actually understand how the browser and the web page interact. Read More…

In the new version of Google Tag Manager, auto-event tracking has received a considerable usability upgrade. It might seem quirky at first, especially if you’re used to the old auto-event tracking method, but the logic behind the new setup is brilliant. The most important distinction is that auto-event tracking isn’t something you control with separate tags anymore. Rather, it’s now entirely trigger-driven, meaning you activate and specify the auto-event tracking of your choice using tag triggers (triggers are what ye olde folk used to call rules). Read More…

I’ve written a completely revamped version of this toolset for Google Tag Manager V2. Well, I just yesterday published the first of my GTM API tools (the Container Visualizer), and I vowed that I wouldn’t release the other tools for a number of reasons. The reasons were good, in my opinion (especially the part about the tools being ugly as crap), but on the other hand I don’t want to keep anyone away from the amazing potential of the new API.

[UPDATE:] Quite a lot of people had trouble accessing the tool after I published this post. This should now be fixed. So, AWESOME stuff. The new Google Tag Manager UI and API have just rolled out, and I can finally start revealing the stuff I’ve been working on :) I’m not going to go into the new UI in this post. I just want to give a huge thanks to the GTM team for working on the UX with such dedication. Read More…

I’ve noticed that setting up eCommerce in Google Tag Manager (and now the new Enhanced ecommerce) is very difficult for many. I’m sure part of the problem is that eCommerce is for many users the moment that GTM forces you to take steps in to the developer’s domain, since it’s obvious that you’ll need to add some code to the web page. This isn’t a tutorial on how to do eCommerce in Google Tag Manager. Read More…

It’s time for MeasureCamp again! As before, I want to write an accompanying post for my session, since there’s always so much more to say than the time slot allows for. So, the topic of this article is the data model used by Google Tag Manager to process digital data in your data layer. This post also picks up where I left in my previous foray into the data layer. However, where the first article aimed to be generic (since the data layer should be generic), this post will look at how GTM uses the information in the generic data layer, and how it processes this information to work with the proprietary features of the tool.

The Page Visibility API for web browsers is pretty sweet. It lets you poll, using some new properties of the document object, whether or not the current page is visible to the user. Visibility is hidden if the page is not open in the current browser tab instance, or if the browser window has been minimized. In this post, I’ll give an example of how features of the Page Visibility API could be used with Google Tag Manager. Read More…

Writing this article is dangerous. Data Layer is two marketers short of becoming a buzz word. This occasion will be heralded by articles such as “Data Layer Is Dead”, “This Developer Implemented A Data Layer And You’ll Never Guess What Happened Next”, and other examples of the kind of content generation whose propagation should be prevented by military force. This is not one of those articles, I hope, but rather an honest look at what Data Layer is from a number of perspectives. Read More…
