How far back do you spray Flonase?

I know you have to aim it toward the outer side, the ear. But how far in do you put the nozzle? I was spraying it lower down but it seemed like it all dripped back out. So I tried spraying it further back (and still to the side). It did not drip back out but when I googled an instruction video, it showed a doctor spraying it lower down. Help!
