Algorithmic social ranking service PeerIndex has introduced one its most highly requested features today, debuting PeerIndex Groups – a new way to track and view the social rankings of groups of people – friends, enemies or competitors en-masse.

PeerIndex already examines social activity across Twitter, Facebook, LinkedIn, blogs and Q&A site Quora, evaluating a users’ “online social capital” based on the activity of the individual across their various social platforms.

With PeerIndex Groups, users are able to create and organise their friends into one easy to view list, ranking them by their PeerIndex rating. Their Authority, Activity and Audience are listed, allowing a user to view the individual elements of an individuals PeerIndex score.

Groups created on PeerIndex aren’t limited to just your friends, they also allow conference organisers to set up a list of attendees at their events, also giving community creators to gather and group members of their community and track them.

It also provides a platform for business owners or media publications to keep an eye on how their competitors rank on the service, providing an insight into what a user could do to emulate their rivals.

Adding A Group

Adding a group is easy. Users need to navigate to their PeerIndex Dashboard, where a new My Groups option will be available:

Once you have named your Group, you need to fill it with the people you want to track or group together. As a test, I grouped a a few of my Mobile-specific followers, manually entering their usernames (which are auto-listed). Alternatively, you can add a Twitter List, taking a lot of the hassle out of adding members.

The group can be listed publicly or you can choose to keep it private and up to 50 users can be added to each individual group.

DISQUS comments are embedded below each group, perfect for events where attendees may want to interact before it commences.
