A domain is the URL or web address where your customers go to find your store online. By default, your online store was given a
myshopify.com URL when you signed up for Shopify. If you want to change the web address that's displayed to customers while they browse your online store, then you need to use a custom domain, such as
www.example.com. You can use domains that you buy from Shopify or from any third-party domain provider. Using a domain that matches your brand can help you build trust in your online store.
If your store is on the Shopify, Advanced Shopify, or Shopify Plus plan and you want to sell to customers in multiple countries or regions, then you can use international domains to set up regional domains for every country or region where you have a target market.
