Lots of good advice above. I'll add a few tips that should help aswell. All living things require three fundamentals to survive. The quality and quantity of these things determine whether the creature will thrive, or merely survive. They are food, water, and cover. Every habitat type has a limiting factor of one or all three. Determine what that limiting factor is, and you'll find the most action! Try to improve this limiting factor if possible. That may be fertilizing mast or a patch of browse, or placing a feeder (where legal), or erecting some sort of water hole. You can't change cover on public ground, so find the safest, best cover and work from there. Look for anything that stands out. Any type of edge, be it a ridge line, a creek line, a clump of bushes or a small thicket of prickers, or a transition area of one type of trees to another.
Also, do what other hunters are not doing. Like hunting mid day, overlooked areas, or hard to reach areas. Try to use the terrain to your advantage. Both for getting to and from your honey hole, and for deer movement. Deer will take the path of least resistance when offered. Clear the trails leading to your stand, and maybe redirect a few leading away.
One more thing, don't be overly aggressive in highly pressured areas. Watch your wind and scent, and use calls and attractant scents sparingly. How many times have you actually heard deer making vocalisations? Certainly not every 10-15 minutes every time you are in your stand. Try to stay as low impact as possible. You want the other hunters to put higher pressure on their areas, and push them into your lower pressured set up. Hunt only when everything is right, not just because you have no where else to go.
