New Google Tag Manager Web Container Client for Server Side Tagging

Enrich data server-side, by combining the incoming data stream with data from APIs and data stores that you own and control. Read More…

ITP Debug Mode in Safari

Implementation Guide for Events in Google Analytics 4

On the surface, tracking events in Google Analytics 4 (GA4) is fairly simple. Events are, after all, pretty much the only thing you can collect in GA4. It’s easy to get tied down with endless comparisons to Universal Analytics, though. While I’m steadfastly opposed to the idea that GA4 should resemble Universal Analytics, it’s still important to cleanse the palate and approach GA4’s event tracking with an open mind. There are some comparisons that can be drawn between the new and the old, but what GA4 might lack in some features and use cases, it more than makes up for this with a more flexible data structure.

Bulk Actions With Google Tag Manager Triggers

The release of bulk actions in the Google Tag Manager user interface was very welcome. For years, GTM users had been struggling with a somewhat crippled workflow of item-by-item management. This release is even more impressive with the most recent update to it: bulk actions with TRIGGERS. You can now select multiple tags and attach one or more triggers (or exceptions) to them. Or, conversely, you can use the feature to remove triggers (or exceptions) from tags. Read More…

Search and Bulk Actions in Google Tag Manager

It’s lovely to see small, incremental, quality-of-life improvements to Google Tag Manager amid the behemothian feature releases such as custom templates in 2019 and server-side tagging in 2020. This time around, we’ll take a look at the upgraded search functionality of the Google Tag Manager user interface, which makes search an actually useful tool.

Partial Container Export in Google Tag Manager

Exporting a container in Google Tag Manager can have many purposes. From backing up Google Tag Manager versions to creating and distributing repositories of useful container snapshots, the container export is one of the most useful non-tagging-related tools that the GTM user interface offers. However, one big misgiving in the feature (until now) has been that exporting just a subset of the container version or workspace has been impossible. It’s always the entire container or nothing. Read More…

The FPID Cookie for Google Analytics in Server-Side Tagging

With Server-side tagging, the developer community has a chance to vastly improve the data collection capabilities of Google’s analytics platforms (Universal Analytics and App+Web). The ability to build our own templates is particularly potent with a Server container. However, it’s not as if Google themselves are just sitting idly by and seeing what the community can come up with. Read More…
