If you plan to present without video streaming during a remote presentation, the most important factor will be your voice.
Your voice is your most valuable tool for building trust when the audience can’t see you. But stand up—you’ll sound more open and relaxed than if you’re hunched over your computer or hovering over your phone. Hold people’s attention by varying your volume, pitch, and tone. But don’t overdo it—melodrama doesn’t earn anyone’s trust.
You can also build trust through the visuals you post. Create slides that convey an “open” feel by using type that’s easy to read and keeping the graphics simple and clean. Also, in the spirit of transparency, let your audience download your deck.
