There are many ways to increase sales on a Shopify store, some of which include:

1. Optimizing your product listings: Make sure your product listings are detailed, visually appealing, and include high-quality images. Use keywords in your titles and descriptions to make it easier for customers to find your products.

2. Running promotions and sales: Offer discounts and promotions to drive sales and attract new customers.

3. Marketing and advertising: Use social media and other online platforms to promote your store and products. Consider running paid advertising campaigns on platforms like Google and Facebook.

4. Email marketing: Build an email list and send targeted campaigns to your customers to promote new products, sales, and other promotions.

5. Improving your website's user experience: Make sure your website is easy to navigate and loads quickly. This will help keep visitors engaged and more likely to make a purchase.

6. Building trust: Building trust with your customers is important. You can do this by providing a secure checkout process and being transparent about your returns and shipping policies.

7. Optimizing your checkout process: Make it as simple and efficient as possible.

8. Analyzing your data: Use the data available in your Shopify store to understand customer behavior and make informed decisions about how to improve your sales.

It is worth noting that not all of these strategies will work for every store. It is important to test different strategies and see what works best for your specific business.
