About a week ago I brought up the idea and theory of Stumble Karma. The theory basically stated that the more you stumble, the more you will build up your Stumble Karma and the more traffic StumbleUpon will send you. To test this I stumbled 10 articles over a period of one hour and about five hours after the 10th stumble I started receiving referrals from StumbleUpon. In all I received 67 referrals, a 670% increase over the amount of stumbles I gave.
To further test the theory of Stumble Karma I thought it would be a good idea to do a second test. The second experiment was to consist of 20 stumbles per day for five days, a total of 100 stumbles. A nice round number that would have sent around 700 stumbles if the percentages stayed the same.
For a number of reasons, I fell short of the original plan of 100 stumbles. Very short. Over a five day period I only managed to give 36 stumbles, a fraction of what I had originally planned. I was actually just about to postpone the experiment, until I could stick with the 100 stumbles over five days schedule, when I glanced at my stats and saw that I had started to receive some referrals from StumbleUpon.
According to Google Analytics, StumbleUpon sent 151+ (I’m still recieving a few) referrals from the 36 stumbles I managed to give. That’s not quite the same percentage of return as before, but still comes close to about 420%.
So does this prove the power of stumble karma? Not exactly. It doesn’t prove that Stumble Karma has anything to do with how much traffic StumbleUpon sends you, but it can’t disprove it either. The only thing that is certain is that both of these experiments resulted in a significant increase in referrals sent by StumbleUpon.
What are your experiences with StumbleUpon and Stumble Karma? Is there anything to the Stumble Karma theory?
