We currently use DTM on most of our websites and need to implement it on another site. Unfortunately our developers won't be able to add the embed code for at least two months because of a code freeze.
To get around this, we're thinking of using GTM. Any problem with doing this?
The code will only be added to two pages: A "login page" and a "login success page". This will be used to exclude existing customers from our marketing reports. I mention this to make it clear that we don't need full implementation on this site.
Code freeze is difficult, if you can manage to get a bypass approval for the dtm tag because it lives in the head tags and not content then maybe your teams can work with it. Not sure. That's the route I'd take. Do it right, or don't do it.
