Never used it, thanks for the suggestion, I will look into that.
Do I understand correctly that when you use Google Analytics it automatically generates a tag and with a tag manager you create your own and have more control?
Almost. With Tag Manager you can have different tags in your ‘container’. So Google Analytics would be one of those tags, you still need to create a Google Analytics account. With Tag Manager you can choose which tags you want to use on different pages or for different consent levels.
This is especially handy if you want to use other scripts in the future, for instance Meta pixel, hotjar, adtracking etc.
