You need to be convincing and in order to be convincing you need to be well-informed.

Persuasive speeches are addressed to people who have their specificities, tastes, manners, habits, viewpoints, behavior and if you want them to understand you, you need to understand them first. Moreover, your comprehension of the character of your target audience will significantly influence your speech itself. At the same time, the audience that already has common viewpoint with you in regard to concern topic will easier become affected by your speech. On the other hand, if your target audience has an opposite opinion, it will hardly accept what you want to say and there will be necessary to convince it by means of other tactics.
- Now it is time to choose the appropriate persuasive approach. This issue depends on the topic itself and on your goal. However, since ancient times people used common basic persuasive approaches in order to convince their audience. They are: ethos (pointed at ethic and moral values which may have the audience); pathos (pointed at the emotional aspect and manipulates with feelings and emotions); logos (the target of this approach is the intellect and logic of the audience). At the end of the day, you are welcome to combine all these approaches if you think it will be useful.
- Create an outline for your key points. When the approach is chosen and you know almost everything about your topic, it is time to brainstorm the main ideas of your persuasive speech. As a rule, it is better to determine from three to five supporting points. They have to be convincing and clear. It is better to have a couple of effective and clear supporting points than many weak and incomprehensible points.
