10 Tips for Presenting to a Large Audience at a Conference
August 1, 2023
A conference talk is a strange thing to give. The room is big, the lights are on you, and you can't tell from the third row back whether anyone is following. Most of the audience has a laptop open, and the next talk is twenty minutes away.
These ten tips are about keeping that room with you.
1. Know who's in the room
Find out who your audience is before you write a slide. Are they practitioners or managers? New to the topic, or tired of hearing about it? The same material needs a different talk for each. If you can't find out beforehand, ask them in the first minute: a show of hands, or a quick poll.
2. Make the first minute count
The first minute decides whether people look up from their laptops. Skip the agenda slide and the "a bit about me". Open with the problem, a surprising number, or a question the room wants answered. You can introduce yourself once they're listening.
3. One idea per slide
A slide that tries to say three things says none of them. Give each idea its own slide. If you can't read a slide from the back of the room, it has too much on it. Split it in two rather than shrinking the text.
4. Let the big numbers stand alone
When you have a result you want people to remember, put it on a slide by itself: one number, large, with one line underneath saying what it means. It'll be the slide people photograph.
5. Keep the design consistent
The same fonts, colours and layouts throughout let the audience stop noticing the slides and start listening to you. A change in look should mean something, such as a new section.
6. Get the room to answer something
Big rooms are where people go quiet, and where a little participation changes the most. Ask a question everyone answers on their phone: "Which of these is your biggest problem?" or "Guess the result before I show it." When the answers appear on the screen behind you, the room sees itself, and you see who's there.
7. Tell stories
People remember stories far better than bullet points. A short case, something that went wrong, or a customer's own words will stick after the slides have blurred together. Put the story where you'd otherwise put a list.
8. Rehearse to time, out loud
Conference slots are strict, and running over eats into the questions, which is often the best part. Rehearse out loud, with a timer, at least twice. Know which two slides you'll skip if you're running late.
9. Speak to people, not to your slides
If you're reading the slides, the audience can read faster than you can talk. Put the detail you need in your speaker notes, where only you can see it. Then use the slide for the point and your voice for the rest.
10. End with what to do next
Don't end on "Any questions?" and a slide of logos. Finish with the one thing you want people to remember, and one thing they can do about it. Then take questions. Better still, ask them one first: "In one word, what will you take away from this?" The word cloud on the screen makes a strong last slide.
Doing this with PPTX.ai
Several of these tips are built into PPTX.ai:
- Big numbers: a layout for a single figure.
- Slides that fit: slides that are too full get split in two rather than shrunk.
- Speaker notes: only you see them while you present.
- Questions for the room: polls, quizzes and word clouds that your audience answers on their phones.
Describe your talk in the studio, and the assistant writes the slides with the questions in place.
Open the studio and start your next talk.
