Overall Satisfaction with Google Tag Manager

We use it to manage our clients' tagging, but also to make sure that we're tracking what we need to monitor how people engage with our clients' websites. Our marketing department will make sure sources & campaigns are tracked, whilst my department (CRO) will track everything from image swipes all the way to someone converting & making sure we've got all available data for that conversion.

Pros

  • Fires custom tags, triggers, variables so we can track what we need
  • Previewing how tags fire before they're published
  • Tracks the smallest of interactions

Cons

  • Needs to reference events fired via the datalayer for maximum robustness, which requires extra departmental support
  • Old tags can remain there for some time unless monitored
  • Tags can break (e.g. a reference changes) and we don't know
  • Using Google Tag Manager means we (as an agency) can control & set up tags & triggers for our clients
  • We can amend a clients' tracking setup for them
  • We're free to track the events we need to track to carry out our work
It requires experience to use. Apart from setting up a Hotjar tag, other tasks require time & a lot of googling
