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.
EDIT: Some of the above links are out of date (Google changed the URL format of dates in Analytics URLs at some point). I created a page that can on my site that can be bookmarked with your Google Analytics report id to get a wide variety of links for various time periods: http://ostermiller.org/calc/ga.html
There's no other way than using a bookmarklet (or browser plugin/extension). I tried the bookmarklet examples above, but none seemed to work for me.
The solution in the first link should work exactly like mine, but for some reason it doesn't. The other 2 links are outdated as Google Analytics URL structure has changed.
The "easiest" way I found to make a bookmarklet works like this:
Don't delete/move/rename the HTML file if you're using Chrome or Firefox, for some reason they need it even after you've added the bookmarklet.
