What is the best approach to test Adobe Analytics implementation (including DTM) for a website which contains 10K+ pages. How could i verify all variables are receiving values or not.?
you can use observepoint or better ask your adobe account team if they will run a scan of your site to make sure the analytics tags are correct.
if you have more than just adobe tags you need to actually get an observepoint (observepoint.com) license to look at hundreds of different tags etc.
but start with Adobe.
