My understanding is that a Segment is a subset of your Analytics data.
In piwik dashboard, I go to “Goals” -> "Overview"
I notice that when I use “All visits (default)”, it has LESS conversions than if I use some setting on Segment (which supposed to be a subset of All visits) In this case, the segment I used was “Page URL” “contains” “…”
How is this possible?
I’ve checked 301 Moved Permanently
which is solved by upgrading prototype, however I’m not using prototype nor custom variables.
