So, okay, I've wondered about this, too. I absolutely get why it would be an issue, but my prints are basically just variations on the same theme over and over -- the state or city or country might vary, but they're all prints of that state or city or country made up of hearts.
It's hard to come up with unique content for something like that. So I've started trying to tweak things here and there, or add a geographically-specific intro (like, a list of things a certain area is famous for then launching into my product description, e.g., "xx, xx, xx, xx, -- there are a lot of reasons to love xx, so...")
It does get taxing, though!
