1. Check technology, sound, and light
Without well-functioning technology, there is no way you can give a good online presentation. You should therefore test your connection, audio, volume, and camera well in advance. Rather than blindly relying on your laptop's speakers and microphone, invest in good headphones with noise reduction. Check how slide sharing and the chat work, as well as how you can get everyone on screen. Do you have good lighting? Daylight looks the most natural, but a good lamp works too. Let the light come from above and from the front. Do not sit right in front of a window, because this makes your face so white that it will disappear in the light.
2. Make your presentation fun to watch
It is harder for people to keep their attention on an online presentation. So make your presentation fun to watch. Make sure you are clearly visible on screen. It is distracting if the camera is too high or too low, or if you only see part of the speaker's face. Make sure your whole face and a part of your upper body are visible on camera. You can sit, but standing is better. Standing not only makes your story livelier, it also helps you focus and breathe properly.
Use slides. On your slides, be sparing with text and generous with images. Change slides often to keep your presentation dynamic. Remember to occasionally turn off your slides, for example when answering questions.
3. Present in a calm and neutral environment
Avoid any distractions during your presentation. A cluttered desk or overflowing bookcase, barking dogs, or children running around: these are all distracting and irritating. Create a professional, calm environment with a neutral background. If you choose a virtual background, also opt for a calm and professional image, and avoid sunny holiday photographs. Before you know it, your audience will be daydreaming about sipping delicious cocktails on a tropical island...
