In more detail
Most social posts peak in the first 24 to 48 hours, then disappear. Evergreen content is the opposite: how-to guides, definitions, FAQs, checklists, and tips that people keep searching for and resurfacing over time. Because it does not depend on a trend, a season, or breaking news, you can reshare and repurpose it again and again without it feeling dated. It is the workhorse of a content strategy, since one good piece can keep paying off long after the work is done.
Example
A post titled "How to write a cover letter" stays useful every month because people always need it, so it keeps getting saved and shared a year later. A post like "Our reaction to today's product launch" is the opposite: it spikes for a day, then nobody looks at it again.
