Great tips! Another key ingredient of a great presentation is 'Consistency'. If you want to enhance the professional look and feel of your slides, you should ensure they are consistent. It is about reducing the unnecessary noise in your PowerPoint slides. Eliminate everything that are not designed to emphasize a key point or concept in your slides. Being mindful of the consistency of colors, fonts, images, formatting, and content will enable you to create presentations that communicate more clearly and effectively. Often using a ready-made PowerPoint template (link to https://slidehelper.com) will help you to adhere to this consistency principal.
