I've been thinking about this a lot lately, and the numbers are hard to ignore once you see them.
A tweet lasts 15 to 30 minutes before engagement drops off. A Facebook post gets 75% of its impressions in the first two to five hours. Instagram gives you maybe 48 hours if you're lucky. LinkedIn is the most generous of the bunch at 24 to 72 hours, and people treat it like a long-term asset. The average lifespan of a social media post across all platforms is around 18 hours.
18 hours. Then it's gone.
I've managed content for brands for 6 years, and this reality still fascinates me. You build a strategy, brief a designer, write the copy, get approvals, schedule the post, and then watch it disappear into the feed before most of your audience even sees it. The algorithm buries it, the next post takes its place, and the cycle resets.
This is the disposable nature of organic social media, and most marketing teams are not honest enough about it.

The standard response is to post more. To deliver more volume, more frequency, more content. Just more. And yes, consistency matters, but volume alone doesn't fix the problem. If your posts are living for 20 minutes, posting twice as many just means twice as many things disappearing twice as fast.
The smarter approach is to think about content differently. Not every post needs to be built for longevity, but some do.
The ones that teach something,
The ones that document a process,
or the ones that make a sharp argument have a second life.
People save them, share them weeks later, link to them in threads, and that should not be an accident. That's structure and strategy doing its job.
The other thing that has worked for me is distribution and repurposing. Essentially trying different formats for the same idea. A post's idea doesn't die at 20 minutes if you're actively transforming it into new formats. Turn it into a short article, pull three quotes for the next week's content, or turn it into a short video.
Algorithms are designed to reward fresh material, and human attention spans are not getting longer.
Fighting that is pointless, and working around it is the whole job.
