Geodes are generally rounded in shape, may have a rough textured exterior, and if partially hollow, would seem relatively light in comparison to an otherwise solid rock.
The only way for the average person to tell if a rock is a geode is to crack or saw it open and have a peek inside. Experienced geode hunters will recognize characteristics in the appearance of its exterior, or perhaps notice that it appears to be lighter in weight than similarly sized rocks, indicating that a partial cavity may still exist inside.
