Focus on features of your product/service
Making a list of the prominent features of your product is the key to grabbing the audience’s attention right from the start of your speech. You can make a mental note as well, however, jotting down the points that highlight your product/service will work best.
Remember, the audience listening to your presentation will not judge you by how good your speaking skills are — they want to know how unique your product/service is.
Believe in your product or service. Otherwise how can you expect your prospect to believe in it? Do not let the audience think for a moment that you do not know everything about your product. Give them as much information about your product as you can.
Use a vocabulary that everyone in the audience can understand. Adapt your speech to the level of the listeners. If your audience is professional, you can use technical terms but if it comprises of general public, use simple language. Restate points in several ways. Take up one thing at a time. Demonstrate before your describe.
Let the listeners share their views
Hold a question-answer session at the end of your presentation. This is the most important part of the whole speech. People may want to ask questions about your products, so let them speak their mind. Ending the presentation without giving the audience a chance to ask questions sometimes leads to confusion, rather than satisfaction.
