You could probably write a whole book on scouting, so it's hard to tell you everything. Some sasy things to look for are heavily used trails. These show you that deer have obviously been there at some time. Also look for rubs (old and/or new depending on time of year), scrapes, and other kinds of deer sign. Funnels are great spots to hunt. An example would be a strip of high, dry ground that goes between two thick, wet swamps or lakes. Most of them aren't that obvious, but just remember that deer like to take the easiest route possible.

Another thing to look out for it edges. Either the edge where a stand of pine trees up to oaks, or just an area with thicker cover than anything else. I remember when I first started hunting, I hunted one woods a lot. There were trails all over, so I'd hunt the trails. I saw some deer, but could never seem to be on the trails they were using. But, when I started hunting along areas where some brushy/thicker cover (Like fencelines, or just natural thicker areas) edged up to the more open hardwoods, I started having deer walk right past my tree. It doesn't take much either. A pretty subtle edge can really concentrate deer movement. Two years after I figured this out, I've seen very few deer on that same property that didn't come within 30, and usually 20 yards of me.
There's just a few basics. Just getting out there and looking is the best way to learn, though it's great to ask a few questions to get you going in the right direction. Good luck and have fun!
