Many free guides on the Internet will give you locations that you can travel to and mine or grind your way to large amounts of World of Warcraft Gold. Don't expect this to work well (or at all) if you are still under level 12.
The reason for it won't work is that you will often be traveling into areas that are filled with beasts that are level 12 or higher and they will attack and kill you when you are within range. You need to be able to defend yourself adequately before leaving your starting area.
