Evergreen Content
Evergreen content is content that stays relevant and useful long after publication without needing frequent updates, in contrast to time-bound news or trend-driven material that dates quickly.
In practice
Glossary entries, foundational guides and FAQ content are classic evergreen formats, and they suit the bulk of a content budget because they keep bringing traffic over the long term. It is still worth looking over older evergreen pieces regularly to correct outdated details, without having to rewrite the core of the text.
