#GTMTips: Embed Facebook Messenger Chat With Google Tag Manager

March 19, 2018 in GTM tips | Comments

A while ago, I published a #GTMTips article, where I showed how you can add HTML elements to the page programmatically using Google Tag Manager. This is relevant because GTM’s validators prevent you from adding custom parameters to HTML elements that are injected directly via the Custom HTML tag. To circumvent this validation, you need to create the element programmatically, before appending it to the document. A while ago, Matteo Gamba asked me a question related to the Facebook Customer Chat Plugin.

#GTMTips: Check Container ID With eventCallback

March 14, 2018 in GTM tips | Comments

When you use the dataLayer.push() command on a page with a Google Tag Manager container, you pass information to GTM’s internal data model and potentially fire tags (if the push() contained an event key). You can also add the eventCallback key to these pushes. The value of this key should be a function, and this function is then executed once the container finishes processing any tags that might have fired on that dataLayer.

#GTMTips: Add HTML Elements To The Page Programmatically

March 2, 2018 in GTM tips | Comments

One of the annoying quirks of Google Tag Manager is that it strips out any non-standard HTML attributes from elements you add to Custom HTML tags. I’m using “non-standard” as a qualifier here, because I don’t have an exhaustive list of attributes that are ignored. But at least data attributes (e.g. data-id) and attributes with custom names (e.g. aria-labelledby) are either stripped out upon injection, or GTM might actually prevent you from even saving the container if the Custom HTML tag has elements with these attributes.

#GTMTips: Check For Undefined Value

February 27, 2018 in GTM tips | Comments

This is one of those #GTMTips posts that I was certain I’d already written. So it came as a mild surprise when I realized I’d never tackled this aspect of Google Tag Manager. It’s a short and sweet tip again. Today we’ll learn how to check if a variable is undefined using Google Tag Manager. Tip 73: Check for undefined variable values If a variable is undefined, it means that a variable with the given name does not currently have any valid value in memory.

#GTMTips: Edit Google Analytics Tag Settings

February 19, 2018 in GTM tips | Comments

When the Google Analytics Settings variable was introduced in May 2017, it resulted in a significant change in the Google Analytics tag user interface in Google Tag Manager. The default UI for editing a tag was stripped down of all GA-specific settings, and the new Google Analytics Settings drop-down was the replacement. Unfortunately, the bulk of Google Tag Manager articles online (including those on this blog) still refer to the old interface in screenshots and instructions.

#GTMTips: Fix Missing Page View Event And Broken Triggers

Google Tag Manager should be relatively easy to implement. Just paste the container snippet to the <head> of the page and you’re good to go! However, at some point you’ll want to configure the dataLayer structure, too (read more about dataLayer here). There are two ways to do it: the right way and the wrong way. In this article, we’ll see what happens if you do it the wrong way, how to identify the issue, and how to fix it.

#GTMTips: Automatically Duplicate Google Analytics Hits To Snowplow

February 1, 2018 in GTM tips | Comments

I’m back with another customTask tip, but this time I’m exploring some new territory. Snowplow just introduced their latest version update, which included (among other things) an adapter for processing Google Analytics payloads. Never heard of Snowplow? It’s a collection of open-source libraries designed to let you build your own analytics pipeline, all the way from data collection, through ETL (extract, transform, load), using custom enrichments and JSON schemas, and finally into your own data warehouse, where you can then analyze the data using whatever tools you find preferable.
