Calculating a combined follower score for social media

[Ian_Parsons]

I'm working on a set of social media metrics for a client, and thought of doing a follower score - sort of like a combined influence rating of all the user's followers. Has anyone done something like this before on Facebook or Twitter?

Also, what would be an effective way of creating this score?

Moz's own Followerwonk does this for you: https://followerwonk.com/ along with using a Moz Pro account to connect in and compare various social media stats. Outside of those, there are several other similar tools:

socialbro.com
crowdbooster.com
simplymeasured.com

Among others. You should be able to come up with metrics using the above. Cheers!
