Set Domain As Primary
You can add as many as domains and subdomain you want to add upon your subscription plan. But one domain must be set as primary by which your store will be visible to your customers.
While setting a domain as primary you must aware that your previous primary domains will not be browsable in the storefront. If customers tries to browse your store with other domains they will be redirected to the current primary domain. Along with that your SEO and Social Media presence might need to be reconfigured and re-arrange.
Consequences of Deleting Domain
A domain connected to a store is the gateway for the customer to access the store and it's product. Also the domain reflects the brand identity. So while we offer feature to delete or update particular domain we highly discourage merchants to delete domains frequently. Deleting a domain potentially can change alter how people discover one store.
