It is simply the content that never fades away or stays relevant to the long is called Evergreen content. In Digital Marketing the content that you write once and take the benefits for a long time or the content that drives traffic to your website on a continuing basis and stays relevant over the years.
All content online is sustainable; the articles and blog posts don’t ever disappear.” When we talk about a piece of content is “evergreen,” we mean that evergreen content is content that continues to be relevant long past its publication, so traffic grows over time.
Evergreen content can be defined as it's doesn't have an expiration date and can't become inoperative.
An example: my Bible-related website is entirely "evergreen" — that is, its 500+ sermons and Bible studies are truths which do not change over time. A message on, say, "The Love of God" is as true today as when I might have written and posted it 20 years ago.
You are right. But it may not be something that one knows completely. Evergreen content is so captivating and useful content on your website that retains its value and relevance for your target audience as time goes on as well as perpetually relevant to readers.
Most probably yours is rite jeromebunker. In my point of view also evergreen content is the content which is created by an individual and that goes on top of the search engine and recognized by many viewers.
Simply put, evergreen content is something that lasts, something that's recognizable and popular among different generations, something that doesn't just follow some actual trend but that has some higher value. Unfortunately, there is less and less of these content, as the modern era requires something trading and popular, but that lasts only for one season, in the best-case scenario.
