Our product is a turmeric latte mix but many people have not heard such a product exists or don't know the health benefits our latte mix can offer them. The product has also been given poor visibility and the retail outlet management has no incentive to shift your product to an area with more visibility.
There are three questions to answer:
1. Are you selling a wonderful product or selling something people know and wanted to have?
2. Turmeric more valuable or the latte? What values are you driving? You are looking for customers to take latte enjoyment or turmeric for health or both?
3. If to bring the wonderful product to a market that doesn't know your product and thus shows no interest in it, how much money you have?
If the answers for all the above three questions are unfavorable, I am very sure you had failed to have your product-market fit. Then your challenge is not above how to increase sales but how to sell the right product to the right customer.
