Where can I find the official documentation for activity types?
Open Email, Click Email, Visit Webpage, etc. - is there any official documentation for these and other activity types? One of the answers somewhat makes it clear https://nation.marketo.com/t5/Product-Discussions/Difference-between-Open-Email-Click-Link-and-Click-Email/m-p/34866#M7301 . I understand that tracking IDs are used to register those activities but I was just wondering if Marketo has listed out all the activity types and provided definitions for them somewhere?
Another related question:
I am trying to get a view on how active people (within our database) are but it seems like different activity types sometimes register the same activity (making one activity seem like two or more). Eg: Visited webpage and Click link activity types can register the same link as an activity, but in reality that was a single action. In general, I am wondering if there are any suggestions on how to go about cleaning the activity data to ready it for analysis? I understand that this is a vague question, but any answers are welcome.
