I have custom analytics which tracks page views and it seems to wildly differ from what Experience Analytics reports. For higher volume pages it seems to be 30% to 60% lower. For low volume pages (i.e. less than 500 visits per month) it can be off by orders of magnitude, with some days having 0 visits even though I know for a fact that is wrong.
I have followed the xDB troubleshooting guide and the results have not improved.
Is there some potential config issue or other explanation for this?
