A2: As I already said, in search of new customers, don't lack in communicating with the existing ones and keep them with you. It is necessary for you to know the LTV- Life-Time Value of your customers. For these, there are some strategies to apply.
Up-sell: You can promote or persuade your customers to buy some more expensive products or add-ons to the one on the wishlist.
Cross-sell: You can convince your customers to buy something to supplement or complement the product they already purchased.
Go for Loyalty programs: Increase your customer to product sell ratio by setting up various schemes for your customers. Any customers will love it if they are incentivized. Provide them with free servicings, free usage offers, discounts, membership possibilities, any other such to let them stick to your products.
Have regular feedback: Never hesitate to ask for feedback for your customers. They will give you the right idea about how to upgrade your product.
