Be sure to have privacy: Spouses, partners, roommates, children, and pets can be a distraction to you or your audience should they interrupt your presentation. Try to get some privacy by closing a door if you can and asking for their cooperation until you are finished.
Check your background: In a videoconference, your audience isn’t just looking at you. They also see whatever is in the background behind you. Make sure your camera is positioned so that whatever is behind you gives a professional appearance and isn’t distracting to attendees.
