The most asked question about social media is: “Why should we be doing this?”. Do a good enough job of answering that question and you will immediately be asked “What is the ROI for this?”. You might be tempted to ask in return about the ROI for the last print ad your organization did or the ROI for taking a customer out on a golf course – but there are better options. Because the impact of social media activities can be measured, can be reported and can be put in relation to the cost involved: the ROI for social media activities can be measured.
At this week’s E-Marketing Insight conference we will present our thoughts on social media measurements, but to start a discussion about this subject we thought we would blog about this and hopefully start a wider debate.
In this post we want to share some of the ways we measure the ROI of social media activities using Twitter as an example.
Twitter is free to use so the only “investment” is the time needed to tweet.
The “return” part or the ROI should be defined as how successful you are in engaging customers through Twitter. Several factors are important and can be measured:
How many times did you Twitter?
Every time you tweet you potentially engage each of your followers. The challenge is that unlike email where you can measure an open rate there are no reliable tools to find out who reads your tweet or not. (Note: there are some tools to measure Twitter “open rates” and we will discuss those in one of our next posts).
How many people follow you?
Obviously the more people follow you, the more people you touch with your Tweets.
How many people follow the people who follow you?
But it is also important who follows you – quality beats quantity. You want people as followers who actively use Twitter and are followed themselves by many other users. Several tools allow you to measure the strength of your network.
(Note: we are measuring the strength of our network but at this point we are not considering this when calculating ROIs or cost per engagement).
How many of your posts are re-tweeted?
Re-tweeted posts engage on a high level. Somebody found your information important enough to share it with their followers. Not only those this take some effort on their part (= higher engagement) but it also gets your message out to people who you do not touch. Re-tweets are one of the highest levels of engagements you can have on Twitter.
How many conversations are you having with followers?
Another high level of engagement are the conversations you are having on Twitter. If you have followers that reply to your posts or ask you questions directly it can result in a high level if engagement.
For our ROI calculation we (roughly) track the time we spend on Twitter and multiply it by an hourly rate. This is our investment.
Example: Time spent twittering per month: 20 hours at an hourly rate of USD 150 = total cost of USD 3,000
To calculate the return we assign values to the different forms of engagement, we call these “engagement units”.
Example for one month:
- Tweets per month: 200
- Average followers in that month: 100
- Tweets x followers = 200 x 100 = 20,000 EU (engagement units)
- Re-tweets: 5
- Value of a re-tweet in engagement units: 1,000
- Re-tweet engagement value for that month: 5 x 1,000 = 5,000
- Conversations: 20
- Value of a conversation: 500
- Total engagement value of conversations: 20 x 500 = 10,000
Total engagement units this month: 35,000 EUs
ROI = 35,000 EU / 3,000 USD = 11.67
Or looking at it another way the CPE (cost per engagement) is 3,000 USD / 35,000 EU = 8.6 cents.
The number itself does not say a lot but repeating this exercise every month allows you to track engagement over time. Furthermore we can now put this number in relation to other vehicles we use for engagement like a website or email newsletter. We suggest using corresponding engagement values for those tools.
Example:
- Email newsletter opened = 1 EU,
- Newsletter forwarded to a friend = 300 EUs,
- Link clicked in the email newsletter = 50 EUs
Cost to produce email newsletter (labor + tools) = 2,500 USD
Engagement created by newsletter = 3,800 reads, 3 forwards, 600 clicks = 34,700 EUs
CPE for the email newsletter: = 2,500 USD / 34,700 EUs = 7.2 cents
And obviously you can do the same thing for a website or a blog using analytics data and assigning corresponding engagement values.
We compare all our forms of engagement on a monthly dashboard. The values we are currently using for the different forms of engagement are not set in stone. We will probably adjust them once we have more data (at the moment we only have 3 months).
Anybody else measuring engagement this way? Thoughts on the values assigned to the different forms of engagement? Analytics overkill or helpful insights?
