Google Tag Manager is well suited when the marketer or marketing team does not work closely with the developers. In this scenario, it means that the marketer can deploy 3rd party tools such as live chat widgets, advertising pixels, and much more themselves in a timely manner. Google Tag Manager may be less relevant in an organization where the marketer is also the developer or has a strong development background, where they can implement the 3rd party tags directly on the site when they need. But even in this instance, there's still great benefit in using Google Tag Manager.

If you need a prompt support for any kind of issue, those guys really rock. I opened tickets on Friday evening getting things fixed in less than an hour. That's a critical point for demanding clients. The main weaknesses in my opinion are the user interface that is not so user friendly and the integration with Google products. This is in place but, mainly due to Google's walled garden, the environment is not so efficient.

Pros
  • Selecting elements on a site [object, class, cookie, etc] (to later fire an event, send some data, etc) is very easy with triggers. Want to add an event when someone clicks on a button? Super easy. It was many many DOM selectors and you can even add custom functions if you need to do something more specific
  • In general, firing events in different circumstances is very easy mixing triggers and tags. You can track almost any element of the DOM and do whatever you want with it.
  • Testing is a great functionality. Only you can see what's on the site and you can debug it easily by seeing which events or tags were triggered and all the DOM elements involved (and why they matched the trigger).
  • Working in environments (staging, production) and versioning is easy to do, deploying changes in 2 clicks.

Cons
  • There are several good integrations, but there can always be more. Native tracking for call tracking solutions, analytics providers, non-Google advertisers would be top of my list.
  • Documentation is just dreadful. Luckily there are some awesome folks out there doing crowdsourced tutorials (shout out to Simo Ahava) but by and large the Google Tag Manager instructions are worth what you pay for them.

  • Sizmek's trading desk was a total miss when I tested it a few years ago.
  • I briefly used Abakus and did not find it intuitive, accurate or helpful. It has a long way to go before it can compete with the likes of VisualIQ.

Until a strong case or need arises for enterprise tag management, I cannot see any reason why we would discontinue using Google Tag Manager. Even if we were to switch to a different vendor, we would still likely use Google Tag Manager to manage Google Analytics code and Google AdWords conversion and remarketing pixels

Google Tag Manager is the best tool to centralize everything in one place including marketing, analytics, integration with third party tools for AB testing, cookie management, etc. it includes user's management, debugging features, tag approval process, etc. it also saves time and resources by not relying on developers.

Support Rating
It depends wether you are seeking official support from Google itself, in which case it would be rated very low because it's not their business model, they would rather have you work with one of their Google Analytics Certified Partner (GACP). In terms of self-served support, Google offer extensive documentation at https://developers.google.com/tag-manager/, recently revamped training (https://analyticsacademy.withgoogle.com/course05/preview), has active forums and user community (https://plus.google.com/u/0/communities/104865292981489764063) which can typically answer even the most advanced questions.

I thought there was a little bit too much emphasis on AdWords stuff, not enough on the generic application of GTM.

Implementation Rating
Planning and communication will help greatly with an in-house implementation. If there are large teams, try to limit the number of people involved to 1-2 developers (back-end dev may be necessary depending on your platform), one analytics marketer and one project manager.

With GTM we are able to integrate GA4 with other platforms we use. We can then send data to GA4 and AdWords and relay that info to our customers. They all work well together and give us a good opportunity to report back to our clients. We haven't used a ton of other products that do what GTM does, so I guess it has a leg up there

When it comes to serving Ads, Doubleclick does a better job with QA and handling creative in my opinion. However the tagging system is more diverse and handy in Sizmek.

Return on Investment
  • GTM has allowed us to show positive ROI for multiple clients via connecting their two websites so that they could see the amount of money advertising generates.
  • GTM has also shown a positive ROI from an internal perspective as we can use templates to immediately upload our standard, customized event tracking which saves hours of testing and configuration.
  • GTM's lack of error catching features has caused more time and individual testing but the improved preview feature has helped save time.
