What do I look at when taking a jumpshot(Basketball)?

Hello, recently I have been trying to improving me jumpshot shooting and I guess you can say that when I shoot I am not the best at it if you know what I mean. I just want to know what do I look at. I do I look at the bok on the backboard or maybe the backboard its whole self. Or should I look at the rim. If there are diffrernt ways can you please tell me so I can see which is best for me. Thank you.
