Some people run websites on current topics, they will be publishing time-sensitive news. These topics have a great search engine value and you might get a lot of traffic. However, after some time these topics become stale and you still stop receiving views. On the other hand, you will not get instant traffic on your evergreen topics but traffic will be built over time and you will continue to receive traffic in the long run.

One needs a balance of evergreen topics. Even the evergreen topics have to be updated regularly to make it still relevant and draw traffic.
