Persuasive Techniques
One of the most important things to keep in mind when performing a pitch is that you are talking directly to a person.. This means that the success of the pitch correlates to how that person is addressed. Correct tone of voice, maintaining eye contact, and overall passion for the product is the key to a good pitch. It does not matter how good the product is, if you cannot convey how good the product is, then hardly anyone will even get to try it.
Another important aspect of a pitch is to keep it to a set time frame. A pitch that is too short may not have enough information, whereas a pitch that is too short may loose the interest of the audience. One of the more difficult tasks is to present the information in such a way as to make the viewer want to hear more, without leaving out important details.
