5 November 2025: Analytics Summit 2025, Hamburg
With the advent of Enhanced Ecommerce for Universal Analytics, a new scope was introduced for Custom Dimensions and Metrics. Product scope can be used to send information about each product that is sent through Enhanced Ecommerce, but it’s not exactly the most logical or intuitive thing to wrap your head around. In this #GTMTips post, we’ll take a look at how to implement Product-Scoped Custom definitions via Google Tag Manager, and I’ll quickly explain how they work in relation to queries and reports you might want to build on top of them.

The inimitable Craig Sullivan gave me an idea for a continuation to my latest post on form abandonment tracking. In this short tutorial, I’ll show you how to track the time users spend on your form fields. We’re going to use the User Timings hit type, and we’ll send the data for just one form.

Especially if you have a webstore, the number of referral sources you need to exclude to avoid sessions being split can grow really fast. Also, it’s not like the list is has the most intuitive UI. Instead of a handy text area where you could just copy-paste stuff, you’re left with a horrible line-by-line list, and there’s no way of copying lists across properties or anything useful like that.

What a nice way to wake up to a new day, when brand-spanking new features have been released for Google Tag Manager. The two features I want to introduce here are Folders in the UI, and code syntax highlighting in Custom HTML Tags and Custom JavaScript Variables. Folders Folders is one of those features that has been requested for over and over again since day one. The UI clutter in GTM is a serious problem, especially when dealing with dozens and dozens of items in a single view.
