I'm currently using both Woopra and Google Analytics (GA) to track customers on my page. I've added custom Google Tag Manager (GTM) code to the site header as well as custom Woopra config script.
Then I've created Tags: one for GA Page View, second for Woopra Page View (woopra.track()). Both tags are triggered on All pages.
I've connected Woopra tracker to fire after GA tracker.
But still, both analytics are off. During the day, it can be up to 200 page views difference (GA: 600, Woopra: 400).
What's causing this problem?
