3. Establish Your Credibility
First, let's define credibility. Credibility is the capability of someone believing in your content. Do you have the credibility to deliver the presentation and win the opinion of the audience? You may be starting out and do not have the experience to use as credibility. It is important to cite credible sources when building a powerful presentation. In order to be persuasive, you must cite sources that have extreme credibility. For example, if you are a marketing professional, you might cite Seth Godin.
