    61 key social media metrics, defined

    This post originally appeared on the Buffer Blog.

    Of all the hundreds of social media acronyms and abbreviations out there, I think “KPI” has confounded me the most.

    I think it’s because the phrase “key performance indicator” always sounds like something you need to be wearing a suit in front of a Powerpoint presentation in order to say.

    But when you get down to it, it’s really quite simple. KPI is just a way of saying “This is the stuff that’s important enough to me to focus on and measure.”

    Basically, social media KPIs, or social media metrics, are whatever is most important for your business. These are the goals and benchmarks that help you determine how well your campaigns and strategies are performing.

    Social media KPIs could be the amount of engagement or shares you’re receiving on your social media networks. You could also track clicks back to your website via social media, or conversions once visitors get there.

    In fact, there are so many different KPIs that it can be tough to keep them straight sometimes. In this post, we’ll look at a variety of social media metrics you might choose to focus on, with a brief explanation of each and how to measure it.


    First, a quick view of the social media funnel

    Funnels probably deserve a post of their own, but for our purposes here it might help to keep an image in our eye of what a typical customer journey with a brand or product looks like (or one version of it, anyway), courtesy of a great visual from Intersection Consulting.


    There are measurement opportunities at every stage of this journey. These are the big sections we’ll focus on in this post (click on any section to go to those metrics directly):

    Activity metrics: The output of your social team


    These are the numbers that show what you’re doing, the basic output of your social media team — including posting, scheduling and optimizing content, answering questions and solving problems. These can appear quite simple but become important to measure as you experiment and try new things. It’s great to be able to say whether increases in your activities produces increase in some of the other metrics we’ll be mentioning later on.

    Reach metrics: Your audience and potential audience


    These are the metrics that focus on your audience and potential audience’s size and growth rate—as well as how often and how well your messages are tapping into that audience. Many social media management tools (like Buffer!) provide a number of these kinds of metrics.

    Audience growth rate: The rate at which a brand adds (or loses) audience members per channel, found by dividing new audience members by total audience members

    At this stage, those who were once simply chatting with your brand on Twitter or Facebook may begin to dive deeper, poking around your site to see what you have to offer.

An analytics provider like Google Analytics can offer many of these metrics.

    • Referral visitors –Those who find your site through another blog or site.

    Conversion metrics: Actions, sales and results


    The ultimate goal you hope a visitor will achieve with your brand is the focus of conversion metrics. Your conversion might be a sale, a subscription, a download, a signup or many other things. Again, a tool like Google Analytics might be handy here.

    Retention metrics: Happy customers and brand evangelists


    These KPIs—many of which go beyond the traditional social media metrics and into general business metrics—cover the last and perhaps most crucial state of the customer journey. This is where we make and create happier customers who can go on to be a brand’s most important sales force—in other words, we turn the funnel upside down.
