5 November 2025: Analytics Summit 2025, Hamburg
A couple of days ago, I wrote an article on tracking content engagement. Even though the solution itself works, and it’s a really neat trick if I can say so myself, it has its problems. After all the glory I showered on User Timings in Google Analytics, they have one serious flaw: they cap at 10,000 samples per day. What a ridiculous, arbitrary limit. In any case, this means that if you have enough traffic to accumulate 10K user timing hits per day, it means that the solution I provided in the previous article will not work for you, as the Pageviews will not be capped, meaning the calculation of Total Engaged Time / Pageviews will be skewed.

When looking at Google Analytics reports, you’d think you get a pretty good idea of how people are interacting with your site, right? I mean, you’re tracking events here, pageviews there, and user timings, custom dimensions, custom metrics, and calculated metrics are all part of your daily lingo. But you’re also probably aware of how futile this tracking is. After all, all you’re seeing are numbers that reflect certain outcomes the visitors have produced on the website, and how these outcomes match against your preconceived goals and objectives, right?

This is a really cool feature for Google Analytics data collection, of which I’ve heard very, very little buzz. It’s a way to debug any and all hits sent to the Google Analytics endpoint at https://www.google-analytics.com/collect. In all simplicity, you just need to copy the entire URL of the HTTP request to your clipboard, paste it into a web browser, and add /debug between the hostname and /collect.

Every now and then I run into a problem which needs some creativity to find a fix. When choosing a course of action, I tend to land first on an extremely complicated solution. However, if I’m patient enough, I manage to whittle it down to something far more manageable and efficient. In this #GTMTips post, I’ll show you one of these extremely simple solutions to a problem which you might normally overcomplicate.

In this article, I’m going to tackle one of the most frequently asked questions out there: Can you run Google Analytics using the snippet AND using a Google Tag Manager Tag on the same page? There are many facets to this query, so I’ll try to tackle as many of them as I possibly can. First, a terminology rant. You hear lots of talk about “on-page” and “inline” Google Analytics tracking, as that’s what’s used to describe the non-GTM way of tracking Google Analytics.

Hello friends! Today I want to direct your attention to a dangerous setting found within the bowels of the Universal Analytics Tag template in Google Tag Manager. In fact, GTM itself highly discourages you from meddling with it: I actually agree with this warning. It should be highly discouraged, as modifying the tracker name introduces a potential hazard to your tracking plan, unless you know what you’re doing.

Google Tag Manager’s Data Layer is something I’ve touched upon in pretty much all of my articles. It’s such an integral part of what makes a tag management solution great and applicable to a host of business scenarios. I’ve also talked at length about the internal data model of Google Tag Manager, and this #GTMTips post is very much related to this rather murky concept. In this post, we’ll go over the Data Layer Variable Version selection, and I’ll try to explain just what this selector does.
