I've been working with Adobe Analytics for some time now, but I've never been able to find a DTM process for implementing new tags easily.
I an All page load rule (for counting page views on any pages).
This rules take all the basic data elements defined on the data layer that should always be found (page name, button name, timestamp, etc..).
The problem arises when there are "special" pages with more data that we would lik eto collect (for instance the Logging Page )
These pages need new rules that will also trigger a new hit. In order to avoid that, I add conditions on my all page rule that stops this one of being fired so we don't have 2 hits. But sometimes this is really tedious since there can be many custom conditions to be added based on the navigation and hierarchy - and also , this is difficult to manage.
So my question is, is this the usual approach to tagging with DTM ?
I ve been thinking to add all the evars and props we track (even though not all the pages have the data layer that gives a value to the data element ) to the all page and all actions rule, but that would show many "undefined" values on Analytics right ?
Could someone please share his or hers best practices regarding tag management ?
