Know where the bedding areas, feeding areas, and transition areas are where you hunt. When I first started hunting, I would set up in the most beautiful oak bottoms or green fields I could find, I realize now that there wasn't always a bedding area nearby and deer were really only reaching those spots at night.
Also, as others have said, know where deer are going and coming from and position yourself so your scent is blowing the opposite direction.
