When I joined a dating site I put down:
all my hobbies,
food I liked
movies I enjoyed
type of humour (very important)
religious and political views

Most importantly I put down exactly what I wanted from a man and what I could give him in return. I was brutally honest about what I would not put up with, and all my good qualities. It worked and I will be moving in with him later this week.

If you are clear about what you want you are more likely to attract a perfect woman to you. Good Luck
