Yes Becca, even good stories can be touched up a little and thus improved.
One technique that I use (when I think about doing it!) is to re-visit old stories and see if I can refresh them with edits, top-to-bottom, including a consideration for changing the title.
When the edited document is saved and thus effectively republished it often gains new readers!
I've written a guide on how to refresh old stories:

Hope this is useful,
