Linking your Shopify domain to your Shopify store is easy and straightforward. First, you'll need to log into your Shopify store and navigate to the Domains page within the Online Store area. Once you're there, click the "Connect existing domain" button and follow the instructions.
When prompted, enter the domain you want to link, and then click "Next" once you're done. Shopify will then verify that the domain isn't already being used.
Once the verification is completed, Shopify will then provide different options for setting up your domain. Depending on the domain registrar, you'll need to login to your account to make the necessary changes.
Once you've setup all the DNS records, return to Shopify and click the "Finish Setup" button to confirm the domain connection. Once the process is completed, you'll now have a domain connected to your Shopify store.
If you have any trouble setting up your domain, please reach out to Shopify's support team for further assistance.
