Do you create fresh Pins for old blog posts, or move on to new content?

I have seen different opinions on this.

Some creators regularly design new Pins for articles they published months or even years ago, while others only create Pins when a new blog post goes live.

If an older article is still relevant, do you keep making fresh Pins for it, or do you prefer spending that time promoting new content instead?

I would like to hear what has worked better in your experience.
