The Agile Project Manager’s Guide to the Lifespan (Half-Life) of Social Media Posts

Note: Earlier versions of this article were published at ScottGraffius.com. Here is an example.

In the rapidly evolving and increasingly digital-centric business landscape, the lines between roles are often blurred. Today, digital marketing frequently extends beyond those in the Marketing department. This underscores the need for agile project management professionals to build and level up the digital marketing information, skills, and capabilities in their toolkit. That includes the longevity of online media, which this article covers.

When content is posted on social media networks, its relevance and engagement are fleeting. Most posts achieve half of their total engagement (such as likes, shares, and comments) soon after posting, with the remaining interaction trailing off over time. Said differently, the pattern typically forms a positively skewed unimodal distribution where peak engagement occurs early, followed by a long tail of diminishing interaction. Understanding this dynamic through the lens of half-life—the time it takes for a post to garner half its total engagement—provides an advantageous, objective strategic metric for content planning and scheduling.

Reports by others related to the longevity of social media are often outdated or based on the experience of one person, one organization, or one limited set of data. With any of those common limitations, findings can be at risk of being non-representative, inaccurate, or unreliable.

It’s important to have a large dataset from multiple sources. By amalgamating a considerable amount of data from various sources, results will more likely be appropriately representative, accurate, and reliable. This approach also provides a more complete picture and helps identify trends.

In 2018, Scott M. Graffius first published data on the average lifespan (half-life) of posts on Snapchat, X (formerly Twitter), Facebook, Instagram, LinkedIn, YouTube, Pinterest, and blogs based on a large dataset composed of multiple, diverse sources. Algorithms and other factors on platforms change over time. For that reason, Graffius periodically updates his analysis.

A visual from the current (2024) edition of his ‘Lifespan (Half-Life) of Social Media Posts’ is shown below and the details are on his website
here.

As conveyed above, the average half-life varies by social media platform. Data can help inform strategic and tactical decisions such as the frequency and scheduling of posts.
