There are over 400 variables that go into the Klout score. While you may see an increase in certain factors such as retweets, likes, or people in your network, there may be other factors that are offsetting this gain. For example, engagement on your Facebook may be changing at the same time resulting in a net decrease in score.
To help you understand your influence better, we've added insights to your dashboard. Just check out the moments feature which shows you how much impact a post has on your Klout Score for example.
Note that it's normal to experience score fluctuations when adding and removing networks. Your score should be back to normal after a few days of doing so.
