Detecting sub-groups in the Econsultancy Twitter network
The most famous example of a sharply divided online community is Lada Adamic’s analysis of US political bloggers during the 2004 presidential election.
Her visualisation clearly shows Democrat (blue) and Republican (red) camps, with very little communication between them.

Online communites are rarely this sharply divided, especially when they revolve around (hopefully) less contentious topics such as digital marketing.
In these networks, sub-groups overlap and don’t have clear borders. A person can also be a member of several groups at the same time.
Nevertheless, most social network analysis software allows us to identify sub-groups or cliques within the community, and this is a useful way to probe any community and work out how it divides up between related interests and concerns.
Network visualisations also encode attributes as position, so users close together in the visualisation tend to be closer together in outlook, expertise and attitude (because they are connected directly and/or share mutual connections).
By examining the Econsultancy network we find areas of the network dominated by digital marketing specialisms (eg SEO, social media marketing) or tweeters from a specific region (such as London, Asia, or the East Coast of the US).
As marketers, it’s also useful for us to know that users in the centre of any network – the ‘network core’ – tend to embody norms and have more power over the flow of information.
Using network insights to develop content
In offline networks, networks of relationships within companies and other organisations for example, influence tends to map loosely (but not completely) onto rank and positions of authority. Online and in social media, however, influence is much more about platform-specific qualities, such as the quality of the content you share.
For this reason, looking at online influencers gives us important clues about the type of content we should create. The content an influencer has shared is often what has made them influential, giving them the reach into the community we aspire to.
By segmenting influencers by sub-group, we can also develop a content strategy that reaches all parts of the network with equal effectiveness.
For example, we may have planned to create content that would go down a storm with a certain group in the network, but leave others cold. We might be able to tweak it to appeal to all members of the network, or have different content strategies for different sub-groups.
Pulling it all together
So if you had a client who was interested in reaching members of the Econsultancy network on Twitter, how could you use this information we’d found?
Firstly, you should look to develop relationships with the people we’ve identified as having high centrality or betweenness. These are the people with the most reach into the network, the most visibility to others, and the most power to make and break messages.
Next, you should look to make sure you’re working with a set of influencers who are able to reach the whole of the network. It’s pointless working with a group of highly visible people if they are all highly visible to the same small group. We need to make sure we have a good spread and can reach all the people who matter.
Finally, you should optimise your content. The influencers and sub-groups we’ve identified give us clues about what our community finds interesting and what kinds of content they are looking for.
The potential of social network analsysis
In this series of posts I’ve only touched the surface of the insights that are available through network analysis. SNA has lots more potential – for example, it can help us understand how information flows through our audience, how many people we need to persuade to reach a critical mass of advocacy, or how we can increase the chances our content goes viral.
But I hope I’ve given you a sense of the enormous potential this technique has for our work as digital marketers.
