Seriously. Is a keeper a shot that is 'good enough' to use? Then you should have a bunch from a typical shoot. Is a keeper one that knocks you flat? Usually fewer of those.
If you're in the studio, working with a good or great model and an MUA your ratio should go up. If you're out in the world street shooting and just taking whatever the world puts in front of you --this is my experience anyway- you can go all day and get lots of 'good' shots but maybe one or two genuine 'let's print this and hang it' keepers.
I've been doing a lot of headshot work with actors and agencies lately and have noticed that the actor almost never picks the same 'keeper' shot as the one the agency picks.
And don't forget, your own definition of a keeper should change as your skill level increses. I know when I go through my keeper files from a few years back some of it still holds up for me and some of it...well...
