An article’s lifespan can be as short as a day or as long as several years. There are pros and cons to updating old blog posts.
On the one hand, it can be nice to freshen up a post and add new information. On the other hand, if an older post is no longer relevant, it can be deleted without much thought.
Deciding whether or not to update an old post is a personal decision.
Ultimately, whether or not to update an old post depends on the content, the age of the post, and the overall relevance of the information. If an old post is no longer relevant, it may be best to delete it.
However, if the content is still relevant and updated, it may be worth keeping it up for readers.
