The Merriam Webster dictionary definition is – ‘retaining freshness or interest: perennial’, which, to be honest, is a pretty good way of describing it.
‘Evergreen’ is a type of content that remains relevant indefinitely. It will still be interesting and gain shares across social media platforms for weeks, months and even years after the day it is published. Unlike news articles, it doesn’t have an expiry date of sorts. And it should hold a valuable spot in search engine results for a long time.
