Focus on getting your first few sales and use those to gain momentum. Ask for reviews and testimonials from your first customers and maybe offer a small discount if they introduce other customers.  Also. optimize your website for conversions. This means creating clear, compelling calls to action and minimizing distractions that might detract from the purchasing process. You could also try retargeting ads to reach customers who have already shown an interest in your product.  Another effective strategy is to personalize your marketing messages. Use data about your customers' preferences and behavior to create targeted campaigns that speak directly to their needs and interests.
