Answer:
Marketing 101
1. Give people a reason to listen to you.
2. Show people that you truly care about them and their needs.
3. Give people a reason to trust you.
4. Present your ideas in terms of pros and cons that will connect with your audience.
Step-by-step explanation:
1. You will never persuade or sell a product to a large group of people if they don't listen to you, I would say this is the MOST important step.
2. If you don't build trust between both parties (you and the buyer), they will think it's a sketchy product, and they will not buy the product. Now, there are boundaries between caring too much and too little: If you say you care too much about their needs, it will sound fake and they will not be persuaded. If do not care enough about their needs, they will think you are a bad person (also bad).
3. Again, like the 2nd point, they want something to trust in or be safe buying the product.
4. If you don't present the product with pros and cons, they will think it's fake. What I mean by this is that, if you present your product only saying that the product is very good, and not telling them the cons, they will think it's fake because you would be overselling the product, for example:
Overselling: Yo buy this product, its so good for (blank) and it will help you with (blank) and you know its good for doing (blank).
Bet you won't buy whatever that product was. The person was overselling. It sounded fake, and it did not sound formal, the "Yo buy this" was totally informal and very sketchy. It was basically and infomercial.
Sometimes you can just not follow any of these steps, get lucky, and sell something... It would be very difficult though.
Hope this helped!
