In this instance, Google discerns the user’s search intent and
decides showing articles related to the newest UK royal baby would
be better than showing an article that is arguably more rank-worthy
due to authority, etc.
What this algorithm update doesn’t mean is that newer content
will always outrank older content. Google decides if the “query
deserves freshness” or not.
If it does, then the age of content becomes a more important
ranking factor.
This means that if you are creating content purely to make sure it is
newer than competitors’ content, you are not necessarily going to
benefit.
If the query you are looking to rank for does not deserve freshness,
i.e., “who is Prince William’s second child?” a fact that will not
change, then the age of content will not play a significant part in
rankings.
If you are writing content every day thinking it is keeping your
website fresh and, therefore, more rank-worthy, then you are likely
wasting time.
It would be better to write well-considered, researched, and useful
content pieces less frequently and reserve your resources to
making those highly authoritative and shareable.
