Beyond Vanity Metrics: Measuring Social Media Success

Brands continue to invest more in social media marketing each year. In fact, HubSpot found that 74% of global marketers currently invest in social media marketing. And with this adoption, theres been enormous amounts of data collected in an effort to measure the success of social media campaigns.

But for many marketing teams, its becoming a challenge to sift through the wide range of metrics to understand if their social media campaigns are effective. Thats why we’ve asked social media experts how they determine success and what metrics you should track that actually matter.

The Importance of Using Social Media to Recognize Employees

Like any Fortune 500 company, public safety agencies should be active users of social media if they want to thrive in todays information-rich environment. Content on the big four platforms—Facebook, Instagram, Twitter, and YouTube—is accessed by more than a billion people worldwide. For many people social media is the first thing they check in the morning and the last thing they see before they sleep at night.

While most of us all have personal social media accounts where we post our cat videos and vacation photos, there are still agencies that don’t have official social media presences. My argument is that all public safety entities should maintain an active presence on at least one of the larger social media platforms, because the benefits of doing so far outweigh the costs in time and effort.

While there are many reasons why every agency should have a vibrant presence online (many of which are unique to individual departments), my favorite benefits all relate to recognition: staff recognition, agency recognition, and interagency recognition.

Visualizing the Social Media Universe in 2020

Social media has seeped into virtually all aspects of modern life. The vast social media universe collectively now holds 3.8 billion users, representing roughly 50% of the global population.

With an additional billion internet users projected to come online in the coming years, it’s possible that the social media universe could expand even further.

How the Networks Stack Up
To begin, let’s take a look at how social networks compare in terms of monthly active users (MAUs)—an industry metric widely used to gauge the success of these platforms.

Lawsuit Challenges Clearviews Use of Scraped Social Media Images for Facial Recognition

Facial recognition technology is getting more sophisticated, more reliable, and more pervasive as the world eases its way toward becoming an all-encompassing surveillance state. That surveillance state does not even have to be built; it is increasingly ready for deployment as law enforcement agencies cut deals with private companies that have already assembled the tools and databases for use. As with cell phone tracking, that plug-and-play quality does an end-run around safeguards that, at least nominally, restrict government actors, and invites legal challenges based on civil liberties concerns.
