There isn’t a fail-safe social media influencer measurement tool out there, but Klout is probably my favorite.
That’s why I was excited to discover the Klout Chrome extension, which shows any Twitter user’s Klout score in real-time.
Now it only works on Twitter.com, so if you’re a rabid TweetDeck user like me, you’ll have to filter your streams to display Klout scores. (A subject for another post.)
Klout’s formula takes a number of social media platforms into account. The highest possible is 99. Justin Bieber is 93 and Barack Obama is 98.
This could be really useful during breaking news situations or large-scale searches so you know which person, over a long period of time, has apparently built up a good deal of influence, which hopefully means their information is more trustworthy.
