Effective presentations do not happen by themselves. It is through analyzing and doing that a presenter gets better.
Here are 2 presentation tips to help you become a better speaker.
Record yourself on video and audio. There are two opportunities for this - when you are practicing and when you are delivering your presentation. Play the recordings again and again. You will recognize the good parts and the areas for improvement. The recording of your "live" presentations will also provide you with the opportunity to observe the audience's reaction to your talk.
Evaluate yourself. This is a vital step to improve your public speaking and presenting. Without this it will be very difficult to improve. Listen and look for what you did well and also for what needs improvement. Identify where you speak too fast, too slow etc. Be detached when reviewing your performance, but do not be too tough on yourself, you are looking to build on your previous delivery, not to tear it apart.Presentation tips can only help if they are applied.
