I am trying to understand the Actions column in the Visitor Log.
In most cases it shows pages visited on my site, and if user clicked one of the links to another site, then the address that was clicked.
However, in the attached image http://s6.postimg.org/4z0jll61d/Question_To_Piwik.jpg the third row has two actions and both URLs are not on my site but rather on stackoverflow.com. The bottom fourth row has the first action not on my site (java-forums.org) while the second action is on my site.
My site is baruchyoussin.com.
What is the meaning of these two rows with initial actions on other sites?
