From my understanding for activity map, Adobe uses context variables to track activity map. Then I noticed that without a image call, the activity map data saved in context variable can not be sent to adobe server. We want to know all the link clicks on our web site. Right now,we only have rules to track exitlink and file download click. We didn't track the onsite link. If this is the case, did the link click number show in the activity map include the click for internal link?
Even though a call is not triggered when an internal link is clicked, the details for the lick click is sent with the next page view call. Hence, you will see the click data in Activity Map reports for your internal links as well.
