Proper webcam position can make a huge difference in your videos. Raise your laptop to position your webcam even with your eyes, typically a height of about ten inches. Stacking large books can work just fine to get you the height you need. Once you have your webcam positioned at eye level, remember to look directly at the camera.
Avoid the temptation to stare at your screen as you record. Consider placing a post-it note with key details right above the webcam on your laptop. This gives the viewer the illusion that you are looking right at the webcam, while still allowing you to use a few notes to maintain focus.
