No, I can’t believe the ‘almighty’ Google is not as accurate as WordPress Stats. So I thought WordPress.com Stats screwed up. And this post titled How accurate is WordPress.com Stats (vs. Google Analytics)? seemed to prove my theory.

And although my confidence in Automattic and their work is huge, I was convinced they screwed up this time…until I read this sentence in the same topic: “I’m surprised we haven’t gotten more discussion on this matter”.
Having a huge (tech savy) userbase this error of WordPress should have being the talk of the blogosphere a long time ago. So after having investigated further, the answer was embarrassing simple:
WordPress Stats shows the views and Google Analytics show the visits.

So they are both good after all: WordPress Stats for the superficial overview and Google Analytics for the deep analysis. I suggest you get both of them.

Update:
Like ‘dani’ states in the comments Google Analytics shows also the pageviews next to the visitors and a lot of other data.
