Just because you are speaking to a camera, doesn’t mean you are not entirely seen, so have a think about how you show up and how you look. You wouldn’t want to look undressed and lethargic in front of a live audience – and speaking online IS speaking to a live audience, sometimes to a global audience.
You may have heard the phrase, “picture the crowd naked” (which by the way, is not good advice!), but don’t reverse it! Make sure you are wearing pants and other relevant cover-up necessities, so people don’t see you near-naked. I’ve witnessed people reaching for a document or a glass of water and in doing so, showing me their ‘home comforts’ which led me to question how serious they were about the presentation. How you dress is all a part of your preparation which, like a live presentation, is just as important online.
