Google Analytics: SML Pro Blog Traffic Sources: Twitter vs Facebook vs FriendFeed vs Google SEO / 2009-11-01 / SML Data
This is a visualization of traffic sources over a one-month period for SML Pro Blog on Google Analytics, highlighting in particular performance on social networks from Twitter (red), Facebook (blue) and Friendfeed (teal), with Google (SEO) traffic added for comparison.
Important to note also is the network connectivity associated with those profiles:
SML Facebook: 630 friends.
SML Friendfeed: 279 subscriptions
SML Twitter: 767 followers
I think that FriendFeed is a clear winner here. It even outperforms Google.
