Is there a way to change the default date range of 31 days in GA? After changing it and clicking apply, only the current report changes? Next time I use GA, 31 days again???
Here is documentation on GA date range.
Google Analytics does NOT support changing the default date range. Some people have noticed that if you bookmark a specific set of dates, those dates end up in the url. Unfortunately, if you create a bookmark with a specific set of dates, those dates will be static and not change. You will never see new data.
