About Your PeerIndex Score

Your overall PeerIndex score is a relative measure of your online authority. The PeerIndex Score reflects the impact of your online activities, and the extent to which you have built up social and reputational capital on the web.

At its heart, PeerIndex addresses the fact that merely being popular (or having gamed the system) doesn't indicate authority. Instead, we build up your Authority fingerprint on a topic-by-topic level using our eight benchmark topics.

Someone, however, cannot be authority without a receptive audience. A receptive audience is one that listens and is receptive to the discussions of members of the community. To capture this aspect, the PeerIndex Score includes an Audience score we calculate for each profile.

Finally, we include an Activity score to account for an individual who is active and has a greater share of attention of people interested in the topics that they are interested in.

Your Topic Resonance Scores
Related to benchmark Authority are the Topic Resonance Scores. These are a measure how your actions within a topic community resonate with the remainder of the community. Again what goes on in the community is greater than your single action.

We only calculate Topic Resonance Scores for topics that we have found to have a large enough community to produce a reasonable result. While you will only see the top five topics on your Profile page, we calculate Topic Resonance Scores for all topic communities we have detected your involvement in.

Breaking Down The Components Of Your PeerIndex Score
Your Authority Score

Authority is the measure of trust; calculating how much others rely on your recommendations and opinion in general and on particular topics.

We calculate the authority in our eight benchmark topics for every profile. These are used to generate the overall Authority Score as well as produce the PeerIndex Footprint diagram.

The Authority Score is a relative positioning against everyone else in each benchmark topic. The rank is a normalised measure against all the other authorities in the topic area.

Your Audience Score

Your Audience Score is a normalised indication of your reach taking into account the relative size of your audience to the size of the audiences of others. In calculating your Audience Score, we do not simply use the number of people who follow you, but instead generate from the number of people who are impacted by your actions and are receptive to what you are saying.

If you are a person who has an "audience" consisting of a large number of spam accounts, bots, or inactive accounts, your Audience Score will reflect this.

Your Activity Score

Your Activity Score is the measure of how much you do that is related to the topic communities you are part of. By being too active, your topic community members tend to get fatigued and may stop engaging with you; by taking a long hiatus on a particular topic, community members may not engage with a long absent member. Your Activity Score takes into account this behaviour.

Like the other scores, Activity Score is calculated relative to your communities. If you are part of a community that has a large amount of activity, your level of activity and engagement will need to be higher to achieve the same relative score as in a topic that has less activity.

Other Details
Normalization of Scores

Before we present your PeerIndex and other component Scores, we normalize them. This means every number in PeerIndex is based on a scale of 1 to 100, showing relative positions. We find scores presented in this fashion tend to be easier to digest and compare.

We use an aggressive normalization calculation which helps you discriminate between top authorities. The benefit is that you can more easily understand who the top authorities are. The trade-off is that many of us end up with seemingly lower scores.

For example: if you are in the top 20% by Authority in a topic like climate change, it means you have higher authority than 80% of the other community members who we measure within this topic. Your normalized Authority Score for this topic (the one displayed on your page) will be in the range of 55 to 65 (which is significantly lower than 80).

But remember, a score of 60 puts you higher that 80% of people we track in that topic. A score of 65, means you rank higher than 95% of the people we track. And we focus on tracking the top people on a specific topic, not just anyone.

Future directions for the PeerIndex Score

We continually evolve our algorithms to improve their value. In addition to refinements to the Audience, Activity and Authority Scores, we will be:

Improving our range of automatically generate topics using additional semantic processing.
Increasing the sample sizes to remove biases.
Extending various metrics to be calculated on a topic community basis and rolling into the overall calculations.
Surprise enhancements: We have lots of potential refinements to our algorithms in the pipeline, which are top secret until we get them through testing.
Your ideas: We would love to hear your suggestions. Let us know what you think through the feedback tab on the right.
