I'm running Sitecore 8.1 (Original Release), and I've generated a report that is tracking how many times visitors have seen a variation of an internal ad that is on my site. The basic premise of the campaign is that we put a wiki-banner style ad at the top of every page that Sitecore serves up. We want to track how many times each version of that ad is displayed.
I've written some logic that marks which variation is displayed to the user as part of their interaction on the website. I've also written a report to go back through the interactions and report on how many times each variation is displayed.
Here's my problem: The number of interaction records is much smaller than what Google Analytics has.
Google Analytics: 1.2 million PageViews
Sitecore: 884,000 Interaction Records
This disparity between the 2 systems has caused my leadership (and me as well) to question whether or not I'm reporting on the right information.
What is going on with this? How should the numbers compare between the 2 systems? Am I comparing the wrong numbers?
