How do you evaluate the cost-benefit of the government’s digital engagement? As a result of the Improving government online review of measurement standards, several interesting discussions were started around extending the work on valuing and evaluating websites to all digital media.
Evaluation is a key priority for Government communicators. Matt Tee, Permanent Secretary and Head of Profession Government Communications, has prioritised evaluation as a key area of focus, along with skills and behaviour change. This is not surprising given the current economic climate. Government has to account for every pound spent and that means evaluating our communications activity to demonstrate cost-effectiveness.
Matt Tee has also requested that every government department develop a digital engagement strategy by March 2010, alongside the Public Accounts Committee recommendation that every department has a channel strategy, – a sign that digital engagement is being taken seriously.
So, how do we measure it?
As with any marketing communications activity, that depends on what the communications objectives are. However, there are commonalities across different campaigns and across different digital engagement tools and it’s those that I want to explore.
Recently, I’ve been working with colleagues in COI on this problem and we’ve come up with three common measures that appear to work across all digital engagement or social media tools:
- Number of relationships
- Number of user-generated content items
- Number of referrals/recommendations
1. Number of relationships
The number of relationships or connections within a network is a measure of power or influence. For example, it could be the number of followers on Twitter, number of friends in Facebook or the number of subscribers to a blog. In social network analysis, this is the basic measure of centrality within a network, which is called degree centrality.
There are other interesting measures of power within a network. For example betweenness centrality measures the degree to which a member lies between other members of a network. In the Facebook analogy, a person may have 1000 friends but have less influence than a person with 50 friends, each of whom have 1000 friends.

Betweenness centrality from red (lowest) to blue (highest)
2. Number of user-generated content items
The number of user-generated content items measures participation within the network. For example, it could be the number of comments on a blog or the number of videos uploaded to a Youtube channel. It measures the level of engagement of an audience, suggestive of active participation not simply passive interest.
3. Number of referrals/recommendations
The number of recommendations is what many seek. This measures virality, advocacy, recommendability. For example, it could be the number of retweets, the number of ‘share this’ actions or the number of pingbacks. It goes beyond mere participation; it means your content or message is valued enough to be recommended to others inside and outside the network.
We would be very interested to hear any thoughts on this. Many people are starting to think through return on investment in this area and it would be useful to have some level of consensus before applying to the government’s use of digital media for engagement. Let us know what you think.
