If you are just doing your networking business offline, then you are in limited market. That's why you need to bring it online. And you can gain the trust of other people even those who don't know you if you could provide them valuable information not only about what you have achieved as a networker but also how to do networking business in proper way to become successful. So if you don't have your own website yet, it's better to start creating your own.
Then start providing quality contents about your journey in network marketing business. Educate your readers about network marketing to remove their fears of joining. Make them understand the advantages and disadvantages of network marketing business. Do not just tell the good side of it, include also the negative side. In this way, people will start to like and trust you because you are not hiding something on that kind of business.
And make sure that the products you are offering in your networking company could really help people. Do not just talk about how you earn big income because sometimes this seems like a scam to people doesn't know about networking business.
And remember that success could only be achieved by those who are determined and motivated enough to do whatever it takes to be successful.
Do not make assurance, because you cannot be assured that all the people who will join on your network will be successful. It doesn't happen to all networkers and I never knew any networking company that all the members become successful. In fact based on the survey, only 3% out of the number of people who joined networking are really earning. If you make assurance to all your prospects, you'll disappoint most of them in the end.
I think you are just new in the networking business because you wouldn't be asking how to gain trust if you been doing this networking business for many years.
So I suggest that you study well the networking business, know better about your company, products, and compensation plan. And learn new strategies that will help you to attract more prospects on your network. Leverage the internet.
I hope this helps, Good luck!!!
