One of the best things about Facebook is the analytics tool, Facebook Insights, which you automatically get access to when you create a page.
Within it, you can track the number of likes, engaged users, people talking about your content, reach, viral reach and so on, all beautifully graphed for you.
Reach (represented by the blue line on the graph below) is the number of unique people who see your content on Facebook and is one of the most important metrics to track.
It is a key revenue driver for online brand marketers, in fact a study by Datalogix found that campaigns that maximised reach had a 70% higher return on investment.
People talking about this
Represented by the green line in the graph above, this is the number of people who have taken action on your post/page. These actions include: liking, sharing, commenting on, tagging, checking-in and so on.
In doing so, they have created a story which will appear in the news streams of their friends.
This is the number of people who have clicked anywhere on your post eg. clicked through to read an article. By sorting this column high to low, you can see which posts are getting the most interest and then steer your content more along those lines to help you increase awareness of your brand going forward.
The number of likes you have is generally a great indicator of how well your content is resonating with your audience; these people have a much stronger awareness of your brand and are buying-into what you are saying.
Insights also tells you the sources of those likes ie. on page, photo, mobile etc.
Your viral reach is the number of people who saw your content as a result of action taken by their friends. For example, they might like, comment on or share a post on your page which then feeds through to the news streams on their friends pages.
The figure (%) is the number of people who have taken one of those actions as a percentage of the total number of people who saw the post.
