Concur much w/your first 2 responders, so I'll move on from there. May not explain more because I keep getting timed out eve w/a decent typing speed.

If you are burn scenting your clothes and the area hunted wasn't similarly burned, I would drop that quick. Even so, the area if burned, a same cover scent still isn't necessary. Use the wind over trusting cover scents.

If you intend to sit, it's best to do 1-2 all day sits and come back 2-3 weeks later and do a final all day sit. Provide full days so the area can properly be ruled out before hunting other spots later.
Consider rattling or legal game calls your area may permit.

Always use the best cover possible-that still provides shooting chances. Movement and noise can bust you in a heartbeat.

If sitting isn't working for you, change to still hinting.

More acreage mean more scouting work. Find the does, bedding areas, better food sources, various water sources, funnels, marshes/swamps. Hopefully in combination w/ each other. Don't overlook various types of thick brush or steep terrain. Steep terrain you can navigate safely is good, as most people have a tendency to avoid the more difficult areas.

Harwood to pine transition areas are also good.

The deer are there. It's not what you know, but if/how you WORK to apply it. Good luck!
