There are many ways to increase your number of customers. Consumers report they trust the opinions of their friends and family the most. Thus, either your product needs to be memorable enough for your customers to talk about it with others or you can incentivize your customers to talk about your products. One example would be to reward customers for posting about your business on social media. In addition, online reviews are more and more popular. You could incentivize customers to post about their experience and write a review on Reddit or Yelp. This can help generate buzz about your business to other potential customers.
