The first thing that you need to do is to find out every possibility that lies within this topic. Especially when you are selling something, you should not only know as much as you can about the product, you should also know the bad sides of it as well. Having the ability to argue from both sides of the coin really gives you a good advantage over everything else.
Bring them to their knees with a little time pressure and this is something I learned about quite a while ago. Once you are able to convince them that they need to act fast, people will often filter away most of the flak that the product already has. For instance, you need to tell them that the product will sell out fast if they do not make the purchase immediately and once the product disappears, they would not be able to find it anymore.
You also might want to look into something like bonding with them. In the end of the day, you need to be able to build rapport with them, and they need to be able to trust you. When you are thinking about this, you need to be able to push the right emotional buttons with them.Sometimes, agreeing with the person is the best ways to win the person and get them to your side with you and with this, you will make them believe what you are saying. Anyone loves yes men, especially one that is nice and responsive to them.
You also can use the power of association. Tie in whatever you are saying with something that has been branded as fantastic. Once you have that kind of association on your side, you will be able to give what ever it is that you are talking a lot more credibility and a lot more hype. The thing about people and the power of the mind is that it is hard for them to break associations once it has been implanted in their mind.
Also, you might want to set yourself up as an expert on the subject, and this will give you a lot more lout than anything else. People tend to believe other people who are experts at the topic, and here, a few white lies might even help you out with this. Once you can do this, then you will realise that people tend to believe you a lot more than usual.
Lastly, persuasion is the best weapon and you should always assume that no one will believe you . Once you can establish that, then and only then will you always be in the progression to convince someone. That is where persistence comes in and your persistence will come in here. As long as your are convincing them, you are slowly turning them to your pathway of truth and light.
So these are some of the ways you can look into to get people to believe you without a shadow of a doubt.
