Make sure there is white space. This improves the user experience and makes your call to action stand out. Your call to action button (link) should be 20% larger than your logo (depending on the size of your logo). Place button at top of page (left). Web readers tend to track through content in a rough “F-shaped” pattern. So format important images flush left. Display the secondary action below the primary action. Make it obvious which button to click to complete an action.
