There are a multitude of methods of good composition, use of light, and editing that can be used to draw a viewer's eye to the subject of your image. One of the most common and effective methods is leading lines, and this great video will give you several demonstrations of their usage.
Coming to you from Andrew Marr, this helpful video follows him as he shoots the Cape Leeuwin Lighthouse in Western Australia. While the lighthouse itself is surely an interesting subject and would make for a great photo along the coastline upon which it sits, Marr sought to enhance it a bit by using leading lines, eventually finding a series of rocks that led beautifully up to the structure. As he discusses, a choice you'll frequently have to make quite carefully when using such lines is that of focal length (as well as subject distance). You want to give your subject a certain prominence within the frame, else the lines can look like they're leading to nowhere. Using a more telephoto lens (if you have the room) and framing at an identical field size can allow you to take advantage of perspective distortion to bring a distant subject into more prominence, thereby increasing the strength of the leading lines.
