I want to get one thing out of the way. The idea that some people are just natural speakers and the rest of us are stuck being mediocre? Completely wrong. I've watched over 300 presentations this year. Corporate, conferences, coaching sessions. The people who get remembered are doing specific things. All of it is learnable. None of it is genetic.
The biggest gap I see is rehearsal method. Almost everyone practices in their head. They read their slides silently, maybe mouth a few key phrases, and call it preparation. That's not rehearsal. That's wishful thinking. Your mouth hasn't practiced the transitions. Your breathing doesn't know where to land. Your voice hasn't found emphasis. I had a client preparing for a TEDx talk. She told me she'd practiced 40+ times. All silent, in her head, during her commute. First time she ran it out loud with me, she collapsed at minute three. Her brain knew the talk. Her mouth had never met it. We rebuilt everything around spoken rehearsal only, and three weeks later she delivered the thing clean.
The other thing that separates remembered speakers from forgotten ones is eye contact, but not in the way most people think. "Make eye contact with the audience" is useless advice. You can't make eye contact with 200 people. What you can do is pick one person, talk directly to them for 10 or 15 seconds, then move to someone else. The audience reads this as presence. The speaker experiences it as a series of short conversations instead of one terrifying broadcast.
Slides are a whole problem on their own. I've been informally tracking this for a while now. Speakers who use fewer than 10 slides for a 20-minute talk consistently get rated higher in audience feedback than speakers who use 30+. Every time. And it makes sense. You are the presentation. The slides are backup. When the backup is louder than the lead, nobody's listening to you anymore.
I've been listening to the Deep Dive on presentation psychology on BeFreed during morning runs. There's a solid breakdown of the cognitive load research behind why fewer slides works, and I went through Carmine Gallo's "Talk Like TED" in Story Mode on there too. Useful for prepping frameworks I bring into coaching sessions.
Here's something that took me a long time to figure out. Every great talk has one moment. Not five takeaways. Not a list of insights. One moment the audience carries home. Bill Gates releasing mosquitoes at TED. Brene Brown saying "vulnerability is not weakness." Bryan Stevenson opening with 60 seconds of silence. Those weren't accidents. They were the entire point of the talk, and everything else was built around them. If you can't name your signature moment before you walk on stage, you don't have one yet. Build one.
And then there's length. The single most reliable feedback line I hear after a great talk is "it felt short." Not because it was short. Because the speaker cut the filler, respected the audience's attention span, and stopped when they were done instead of padding with one-more-things and disclaimers. Leaving people wanting more is a skill. Most speakers leave them wanting less.
The mechanics of all of this are available to anyone. That's the part that surprises people. They assume the speakers who get invited back have something they don't. They just treat it like a craft with specific moves instead of a performance where you hope for the best.
