Hi SonnyRD,
Do you have already a web tracking system such as Google Analytics, Adobe Analytics, Xiti implemented in your web page?
In that case, you can study from where your visitors come to your Adobe Campaign webApp.
If not, it is not useful to activate the out-of-the-box web tracking in your webApp, in Properties General tab (field @webTrackingEnabled)
(https://docs.campaign.adobe.com/doc/AC/en/WEB_Web_applications_Tracking_a_web_application.html)
because unfortunately the nms:webTrackingLog table doesn't contain @IP address.
So what you can do, if you are On Premise, is to analyse the httpd access log files to see the IP addresses, so you will get the IP addresses and then you can know the domain names/geographical etc and perhaps understand a bit if it comes from a web site.
If there are private IP addresses (ISP providers) it means probably that the users put the webApp in favorite/shortcuts and accede them directly. Or perhaps do you have a emailing campaign that provided to them the webApp link directly ?
For next webApp, please think to add an ?origin=XXX parameter to your emailing campaign pointing to a webApp, and the same for websites leading to your webApp, it helps a lot to analyse origin (in addition of tools as Google Analytics/Adobe Analytics).
Regards
