Klout, the company that claims to help you “discover and be recognized for how you influence the world,” announced today that it is now including data from Facebook Pages in its scoring.

I would have thought this would have been a primary indicator of social influence for quite some time, as Facebook has racked up its over 900 million users, but only now is it coming to Klout Score.

“Facebook Pages are an extremely popular and important platform, where people, brands, and organizations actively engage with their communities,” Klout says in its announcement.

You don’t say.

“The engagement volume is significant,” the company says. “For example, a Klout user with a score between 70-80 has an average of 13,000 users talking about their Page. This engagement explains why Facebook Pages have been one of the most highly-requested additions to the Klout Score.”

The following graph, shared on the Klout blog, shows the new distribution of Klout Scores for users who have Facebook Pages, showing the contribution their Facebook Pages make to their scores:

Klout says your most influential Page content will begin appearing as moments on your Klout profile soon.

It’s been a big week for Klout. In addition to this, the company announced a partnership with Bing, which sees Klout data appearing in Bing’s social sidebar, and an undisclosed investment in Klout by Bing.
