Talk to persuade, not just to inform.

Rattling off facts and figures and talking at the audience isn't effective if they aren't interested in what you are saying.

Be clear about what you want the audience to walk away with when they leave and use that intent as a structure to frame your talk.

Authenticity—sounding like yourself and using everyday language—is key to getting your message across to an audience,

Use visual tools (such as slides or a video) as an aid. Incorporate research and tell stories.
Use anecdotes as an effective way to connect with your audience.

Using different media in your talk makes it more dynamic and compelling. It creates energy and vibrancy.

Think about ways to use slides, video, audio, handouts, props, and even spontaneous smartphone polls to engage your audience.

Determine your main points and outline them.

Use notes or PowerPoint or Keynote slides as prompts. Avoid using only words. Use slides for emphasis.

Have a run-through in the space you'll be speaking at if possible and test the tech system for possible problems.

For instance, the sound may not run properly with your video or your slides may be set up behind you and prevent you from seeing where you are in your talk.

Use humor, an engaging video or other media to present various aspects of topics that needs deeper exploration.

Talking until the last minute is a common mistake many speakers make.

For an hour-long presentation, plan for 45 minutes of talking and 15 minutes for questions.
