Without knowing anything else about the situation, I'd say to give careful thought to the prevailing winds. Select a tree for a stand that will have you scent blowing away from where you expect the deer to come from and where you expect the to be when you hope to get a shot.
Also, try to plan your travel route to and from your stand so that you don't:
a. bump any deer that are bedded
b. leave a scent trail that the deer have to cross to get to your "sweet spot".
If possible, have more than one stand location so you can use a different one for different winds.
These ought to be good ideas for starters - - Good Luck!
