Social media is one of the most important aspects of digital marketing. Well-executed, it provides several benefits: improved brand and marketplace awareness, engagement with a worldwide audience, increased traffic, enhanced search engine optimization (SEO) rankings, and more.
The lifespan of posts is of interest. Because content can live forever, a more helpful metric is half-life. It’s the amount of time it takes for a post to receive half of its total engagements. As shown in the image above and described below, the half-life of posts varies by platform.
Twitter
Facebook
Instagram
LinkedIn
YouTube
Pinterest
Be mindful of the half-life values when posting content.
