Slightly strange thing happened on our site's blog recently - the pageviews per session jumped about 3 weeks ago to the same/above the number of sessions.
Then a few days ago that trend stopped and switched back to what it used to be, with pageviews dropping back into the sort of relationship we normally see.
Does anyone have any ideas as to why this might be, or suggestions as to how I can dig into Google Analytics in more detail to find out what might have caused (and stopped) this?
