• When content is published online, relevance and engagement have a limited lifespan. Engagement is typically not distributed as a normal bell curve. Rather, it’s generally a unimodal distribution-based, positively skewed curve.
• Here’s a description of the prototypical distribution of data (engagement): On average, most posts receive half of their total engagement relatively soon, with the remainder spread out over a comparatively long(er) period.
• For those reasons, an advantageous respective objective metric for posts on social media platforms is half-life. It’s the time it takes for a post to receive half of its total engagement (such as likes, shares, and comments).
• Built on a large dataset from multiple sources, Graffius’ research reveals the average lifespan (half-life) for posts on different social media platforms.
• Note: Findings from others — including anecdotal experience from select posts or otherwise the experience of one person, one organization, or a limited dataset — may vary from the average half-life data in Graffius’ research.

Post-Publication Notes

If there's an update after this article is published, the information will appear here.

Update on 24 March 2025

On 24 March 2025, Frontiers (the publisher) sent an email to Graffius. Here’s an excerpt:

"This is to let you know that the corresponding author has submitted a corrigendum for the article based on your comments. Our editorial team will review the corrigendum."

Update on 24 March 2025

On 24 March 2025, Graffius replied to Frontiers’ email. Here’s an excerpt:

"Please:

1. Inform me know when you’re scheduled to implement the corrections (or an estimated date), and
2. Update me after you’ve implemented the corrections."

Update on 25 March 2025

On 25 March 2025, Frontiers (the publisher) sent an email to Graffius. Here’s an excerpt from it:

"If the corrigendum is accepted, I will send you the link to the online page. There will also be a visible link to the Corrigendum on the original article, as soon as the article is accepted. Once an article is accepted, they are published within 3 weeks on average. Please note that once an article is updated, it can take longer for the update to be reflected in certain repositories, depending on the repository."

Update on 28 March 2025

The most recent update from the publisher was on 25 March 2025. It's noted above.

For context, Graffius reported the errors on 18 December 2024. As of today, that was 100 days ago, and the errors have not yet been resolved.

Update on 14 May 2025

As a recap, Graffius reported the errors on 18 December 2024. On 14 May 2025 — 147 days later — the errors were resolved. The correction notice ("Corrigendum: Public perceptions of digital mental health awareness campaign in the Arab Gulf states: a qualitative thematic analysis") is at https://www.frontiersin.org/journals/public-health/articles/10.3389/fpubh.2025.1597875/full. It reports this:

"A Corrigendum on

Public perceptions of digital mental health awareness campaign in the Arab Gulf states: a qualitative thematic analysis

by Alomair, N., Alkhaldi, G., Alsadhan, N. M., Alkasabi, R., and Alageel, S. (2024). Front. Public Health. 12:1477315. doi: 10.3389/fpubh.2024.1477315

In the published article, the reference for (19) was incorrectly written as “GRAFFIUS SM. Half-life for posts on different social media platforms”. It should be:

19. Graffius SM. Lifespan (half-life) of social media posts: update for 2024. (2024). doi: 10.13140/RG.2.2.21043.60965

The published article erroneously paraphrased the lifespan of social media posts.

A correction has been made to Methods, Data collection. This sentence previously stated:

"The lifespan of social media posts on most platforms is, at most, 9 days."

The corrected sentence appears below:

"Posts on top social media platforms typically receive half of their total engagement (such as likes, shares, and comments) quickly, ranging from seconds to under nine days. After that half-life point, posts start to get buried in the news feed."

The authors apologize for this error and state that this does not change the scientific conclusions of the article in any way. The original article has been updated."
