I would raise the daily rate as applicable if you notice Guest quality is declining or is already low. Otherwise I'd leave it.
It may be good to increase the rate temporarily for certain weekends/holidays if you notice your listing's price is lower than everyone else.
I adjust pricing to make it desirable for the guest(s) that I want to host, but less desirable/not desirable for the guests that I don't want to host. This is especially important for listing(s) like mine that allow instant booking without any conditions.
