Last week we wrote about EdgeRank from the social media infographic from Moontoast:. Part of the iconograph was looking at fans and understanding just how loyal or awesome they are to your brand.

There are five types of fans across your audience:

Fan Engagement Spectrum

• A potential fan is someone who is in the circle of one of your fans who has already “liked” your brand. These fans can be reached through sponsored story ads on Facebook
• An engaged fan is someone who likes your page. This type of fan may see your posts and may not depending on your Edge Rank in their news feed, so these fans are still important as they will add to your affinity and weight.
• An advocate fan is someone who has shared one of your links or uses Facebook connect to log into your website. They are someone who actively shares not only with you as the brand but allows you to post to their wall so they can share with others or send you email.
• Purchasing fan is someone who has purchased from you or donated to your cause
• Super Fans are the highest level of fans, they have not only bought from you but also have had their friends buy from you.

One takeaway from this graph is the possible use of a brand using badges to help get people to promote their brand. Foursquare got off to a great start using badges, showing off your badges for brands on Facebook could be an interesting angle.
