After clearly defining your target customer, you need to expose them to your product. You don't have to go all the way to the sales stage, just get your potential customers used to what you can do for them. Then, thanks to a regular presence on social networks, you can take the next step, which is to contact the people most likely to buy from you. People who put your product in their shopping cart on your website, for example. They are not decided on the purchase, and this is where you will show your know-how as a seller. Even better, once you've done business with a customer, stay in touch with them and encourage them to share their experience, so your first happy customer can find you the next one.
