Most likely you will start your presentation with introducing yourself.
You do it because it is polite to do so. Or because that is what you have seen everyone else practice. If that is how you have started, you have just wasted the most precious time.
Think about this, if someone has decided to listen to you present, there is a high chance that they know who you are. Checking you out online was an important step they took before they decided that they wanted to hear you speak.
So, online credibility is far more important than what you say about yourself in an introduction. We live in a low trust world, so the audience want to be able to find out and decide for themselves if you are worth listening to or not.
Let us assume they don’t know who you are, in that case, isn’t your presentation an opportunity for you to create a desire in them to want to know who are you? What can you do so that they themselves want to find out about you?
One of my fav ways to introduce myself before a speaking engagement is , ” if I do anything right in the next XX mins ( XX =time allocated for speaking ) you will care to find out who I am.”
Your content and delivery, not reciting your resume, will earn you the right of people wanting to know who you are.
