Flickr announced the launch of Flickr Stats, designed stats on Flickr to give you all sorts of insight into how people arrive at your photos.

Activating Flickr Stats: Flickr Stats is only available to Pro users at this time, for you to use this feature, you will need to upgrade your account to Pro status. Once you do that, then you can activate your stats by going to Flickr Stats and clicking "activate." Flickr then tells you to check back in 24 hours, but it only took five minutes for my stats to appear.
