70-point comparison of 6 tag managers

JavaScript tags are a necessity to manage data flow on websites, in mobile apps and in digital products of all kinds. For over a decade, tag managers (also called tag management systems or TMS) have helped analysts create, organize and test a huge variety of tags for data collection and activation.

In recent years, data governance has grown in importance. It’s not enough just to send bits of data here and there. Analysts and marketers need to know exactly what, where and with what justification. 

Regulations such as GDPR and higher expectations from internet users have led to new requirements for tag managers. Assuring data privacy and security has become essential for many use cases.

However, that doesn’t mean that the traditional role for tag management systems has gone away.

Why do you need a tag management system in the first place?

Tag managers make web and mobile tracking tasks simpler for analysts and marketers. Where an IT team may need weeks to implement new code, a tag manager lets you use templates and tag libraries to create and debug tags in minutes.

This puts a lot of power in the hands of analysts and marketers. To make sure data collection is safe and reliable, it’s worth adding a few other things to your tag manager requirement list:

  • Customer Support – Tag managers take care of a lot for you, but at the core, you’re still dealing with complex JavaScript code. It pays to have access to a good support team in case any problems or unknown bugs come up.
  • Privacy compliance and data control – Tag managers give you an incredible amount of control over the flow of data around and outside your stack. To get the most of that, while still keeping data secure, make sure your platform gives you the control you need. This includes advanced features for assuring privacy and security compliance.
  • Integrations and templates – To avoid writing too many custom tags yourself, make sure the platform you choose has the integrations and tag templates you need. This will save you a lot of time when creating, testing and maintaining tags.
