You likely noticed a change in Score on 10/26 because we released a new scoring model. In this change 53% of Klout users saw their Scores go up or stay the same, but some users did see a Score drop, including many of us here at Klout. Our goal is accuracy above all else.
The major changes in this release were:
Greater equality of networks. In our prior model, the main driver of your Klout was a primary network (the one you're best on) and your influence on secondary networks was too small a part of your Score. Now, a person who has two networks that are fairly equal in terms of participation and influence, say Facebook and Foursquare, will see a greater parity in the way we score those two. Of course, you may have a greater potential to be influential on a bigger network like Twitter or YouTube, but given you're influencing the same people in the same way, each network would have the same impact on your Score.
Greater context around actions. In our previous model, we considered the action taken and the influence level of the person giving it. With this new release, we've added in the context of the person giving it. If you only give out one Facebook "Like" a week and you choose to do so to my content, that is much more meaningful than if you "Like" 50 times a day. We are taking this into account in our improved algorithm so we better understand and give you credit for how much you influence someone. This did result in lower Scores for those that are frequently engaged with by high-activity users, but we feel this is an overall improvement in accuracy.
Stability and consistency. Seeing the ebb and flow of your influence on a daily basis is helpful, but we also understand that your influence rarely makes huge jumps in such a short time period. Our new algorithm makes the Klout Score more stable and takes a longer window of time (90 instead of 30 days) into account when measuring your influence.
We've also added Score insights in your dashboard to understand why your Score changes on a daily basis. Keep in mind, the Score is most useful in the context of your friends and peers as opposed to an absolute number. The average Klout Score is around 20 and a Score of 50 or above puts you in the 95th percentile of scored users. We're committed to making the Klout Score as accurate and clear as possible and this is an ongoing process.
