Hi Fred
Thanks for reaching out to us and we’re sorry the settings are confusing for you as a newbie.
You can either use GA only or with the option “Use GTM instead” you can use GTM only. You can’t use both at the same time with the plugin. If you activate the GTM option, you’d have to deploy GA through GTM to register page views etc.
So if you use GTM for tracking other things, you can simply add a regular Universal Analytics Tag to GTM. That way you are deploying GA through GTM. In this case, you activate the option “Use GTM instead” and paste the GTM-tracking code into the field for the GTM-tracking code.
If you only use GA, you don’t need the GTM setting in our plugin and can simply paste the UA-tracking code into the GA-tracking code field.
I hope this helps you pick the right settings for your needs. If you need any help setting it up, feel free to respond here again so we can have a look at it together.
Kind regards
