I'd like to track the number of interactions per visit similar to a page view count per visit. I wonder if this information already lives somewhere within Tealium iQ just like the page view count can be derived from the utag_main__pn cookie? Or do I have to implement it myself?
For the latter I assume it should be sufficient to add another counter to the utag_main cookie simply counting up on every utag.link call resetting the count if utag_main__ss is set to 1. Can you think of any pitfalls with that approach?
