GTM Tips

Here’s a tip that’s especially important to anyone working with a single-page application. Google Tag Manager persists items in its data model until you either manually delete the variable and/or its value from the data model, or until the user browses away from the page. There’s nothing as annoying as the example in the image below, where a value that was set for an earlier Tag is resent with a new Tag, even though the purpose was to leave it out. Read More…

PII (Personally Identifiable Information) is something we need to actively combat against when using Google Analytics, as the platform explicitly forbids sending PII to Google Analytics properties in any size, form, or shape. One of the most common ways of accidentally passing PII to a property is via query parameters. Many email platforms out there, for example, see no problem in including the user’s email address in the query string, especially when the user follows a link in a newsletter. Read More…

Do you want to get the most out of Google Tag Manager as the go-to system for all marketing and measurement tagging on your websites? Take the Google Tag Manager Fundamentals Course at the Analytics Academy, then! And take it even if you have no idea what the tool is. Read More…

This is a very simple tip, but judging by the number of queries on the Product Forums, it should prove helpful. Blogger is a free blogging service by Google. Like WordPress, they allow you to run hosted blogs on the blogger.com domain, and they also allow you to modify the HTML source. This, of course, means that you can add the Google Tag Manager code to the HTML template, if you wish (and why wouldn’t you! Read More…

Google Tag Manager has a learning curve. We’ve all gone through it. The developer guide as well as the new and improved help center are very useful, but they do not answer all the questions a thorough implementation project might face. There are many ways to find answers to your questions, and I thought I’d go through some of my favorite options here. Tip 22: Get GTM Assistance To help you in getting help with GTM, there are two things we’ll need to go over: where to look for help, and how to ask for assistance. Read More…

Here’s a very quick tip this time, but one that’s caused a lot of headache for many Google Tag Manager users. Tip 21: Use the All Pages Trigger correctly Let’s face it, All Pages isn’t really an intuitive Trigger name. Many seem to interpret it as: enable the Tag to fire on all pages, but use the other Trigger (e.g. Link Click) to actually fire it. As it turns out, the All Pages Trigger will fire the Tag on all pages. Read More…

On March 30th, right on (the latest) schedule, the Migration Assistant tool was published for Google Tag Manager V2. This tool lets you opt-in to account migration for your legacy Google Tag Manager Accounts. Migration means simply that the accounts will be converted to V2 accounts, and you will have access to all the new features the upgrade provides. In this #GTMtips post, we’ll go over the migration steps (it’s pretty simple), and I’ll leave you with a couple of tips on how to get started with the new features. Read More…

One of the unfortunate misunderstandings regarding the wonderful Google Tag Manager Preview mode is what it actually means when GTM reports “Tags Fired On This Event”. For many, this seems to indicate that whatever code the Tag was meant to execute also completed successfully. However, this is not the case. Tip 19: Debugging Tag execution vs. actual requests Let’s get the distinction straight right away: Google Tag Manager debug panel tells you when a Trigger has been invoked by certain conditions, and the Tag which uses this Trigger has its JavaScript injected into the Document Object Model.

(Updated 15 July 2015: Added a huge simplification. Jump straight to the update at the end.) URL fragments are strings of characters that follow a hash mark (#) in the URL. Typically, they are used for anchor links, where following a link keeps you on the same page but jumps the browser to some anchored position. They’re also the tool of choice for single-page apps, where content is served dynamically without page reloads. Read More…

In Google Tag Manager, every single Tag requires a Trigger to fire. Every single Trigger requires an Event condition to activate. Sometimes, these Event conditions are obfuscated under template semantics, but you can also create a Custom Event Trigger, where you specify the value of the ‘event’ key in dataLayer that fires your tag. You can read more about the relationship between GTM events and Tags in these two posts: Read More…
