1. You can have campaigns! Small campaigns around the school can help you get votes! It's better if you have friends to help you though :D
2. If you're a social butterfly, it can help too! Socializing with people around your school can help raise votes! If you're not one, try knowing other people well.
3. Being a homecoming queen isn't all about getting votes, you should try managing your appearance! Take care of your appearance, (have beauty routines, etc). Wear nice clothes! Being a homecoming queen needs to have a great taste in fashion! <3
4. Be nice, smile, be kind, don't make enemies with the rivals! And have fun!
Good luck! :D
