Changing Domains

All BigCommerce stores are initially created with a domain, or website address. While you are free to use this domain indefinitely, you will want to research and purchase a custom domain for your store to advertise and market your business more effectively and to attract more shoppers by making it easy for them to find you.

If you've obtained a domain through a third-party (e.g GoDaddy), you'll need to direct it to BigCommerce to start utilizing it on your store. Adding a custom domain name to your store consists of two steps:

  • changing DNS settings in your registrar (e.g. pointing nameservers)
  • changing your store's domain in BigCommerce

If you purchased the domain name through BigCommerce, the nameservers are automatically pointed for you. No extra steps are necessary.

Additionally, we'll automatically install our free Encryption Everywhere SSL certificate so your new domain will be immediately secure. You can also upgrade to any of our other premium certificates at any time.



Before deciding to change domains, it's important to know that in almost every case this will have a negative impact on your SEO. Some of the steps and tools listed below can help you minimize this impact, however, be sure to check the resources for additional non-BigCommerce specific information.

Once you have changed your store to its new domain, it will no longer be accessible on the old domain. When search engines attempt to crawl the old domain, they will receive 404 errors. To minimize any negative SEO impact this may have, you will want to reset the old domain’s DNS back to the registrar's default settings, then redirect the old domain to your new one.

Updating the DNS for your old domain to the registrar's defaults will cause all email traffic for that domain to point to the registrar. Although not required, consider asking your registrar to set up email forwarders for any of your old domain’s email accounts to their counterparts on the new domain.


Pointing Your Domain

There are three possible ways to point your domain to BigCommerce:


Pointing Your Nameservers to BigCommerce

Pointing your nameservers to BigCommerce is the recommended way to use your domain with your store. To point your nameservers, you will need to log into your domain registrar, the service you purchased your domain.

1. Log into your domain registrar account.

2. Locate the area to change your nameservers, usually under DNS Settings. If you have trouble, the registrar's knowledge base or support team will be able to provide you specific information.

3. Add the following nameservers. Depending on your registrar, you may need to choose a custom setup type to add new nameservers.


Pointing a CNAME to BigCommerce

A CNAME (canonical name) record is a type of DNS record that points an alias name to a root domain. CNAME records are typically used to point a subdomain to a root domain (i.e.

To point a subdomain to your BigCommerce store, create a CNAME record that points to your store's permanent address. A benefit of pointing a subdomain is that you would not need to update any preconfigured email settings. They would still be managed by your registrar.

1. Log into your domain registrar account.

2. Create a CNAME record. If you have trouble, the registrar's knowledge base or support team will be able to provide you specific information.

3. Use the following settings:

  • Alias — the domain you want your store to be on (e.g. or
  • Host / Points to — your BigCommerce permanent address (e.g.
  • TTL — how long the server should cache the information, measured in seconds (e.g. 3600)

Pointing an A Record to BigCommerce

Pointing your domain via an A record involves creating an A record at your registrar that points to your store's IP address (see  Finding Your Web Address). Please note that this method is not recommended since store IP addresses are not static and are subject to change. If your store's IP address changes, the A record will no longer link your domain name and store, resulting in a blank page.

If you do choose to use this method to point your domain, locate your IP address and contact your domain registrar for assistance with updating the domain's existing A record to point to it.


Changing Your Domain in Bigcommerce

If your store is on a .mybigcommerce domain, you can:

If your store is on a custom domain, you can:

If you have an unassociated domain, you can:

If you do not already have a domain name, one can be purchased from your control panel. Domains purchased from BigCommerce will automatically apply to your store saving you the hassle of pointing DNS records. Note that domains purchased from BigCommerce have basic DNS capabilities and can be transferred between any of your stores.

Multiple domains can be on your account, but only one can be associated to a store at a time. However, it is possible to have multiple domains lead to a single store. See Using Multiple Domains for more information.



When making DNS changes, it can take up to 72 hours for the changes to be reflected globally. This is due to a process called propagation. The length of time it takes for this process to finish is known as propagation delay.

There are two parts to DNS changes:

  1. the initial DNS update in the registrar
  2. the changes updating throughout the web (propagation)

For DNS propagation to occur, your registrar's server communicates the update to the DNS servers nearest to it. Each of those servers then communicates the change to the servers nearest to them, and so forth. This propagation continues until every DNS server in the world has made the update.

As you've probably guessed, this means that there is a geographical component to how quickly you will see your DNS changes go through. If your registrar's servers are nearby, you will see the changes much more quickly than a customer living across the world. So although the changes can take up to 72 hours, it usually occurs within an hour or so — sometimes even less!

You can use to check the progress of your domain. Be sure to change the record type to NS.

Viewing Your Store During Propagation

If you have changed your store's domain but are still waiting for propagation to complete, you will need to use your store's permanent address until your DNS changes have completed.

You can use this URL to preview your store until your DNS changes have fully propagated. To preview pages other than your homepage, add the end of the page URL that you are attempting to view after the .com in your permanent URL.

For example, if your contact page's URL is, use to preview the page.


Using Multiple Domains

You may want to have multiple domains that lead to your storefront. It can be useful if you are renaming your store and need a new URL or if you're going to start using a subdomain.

This can be done on BigCommerce by setting a single domain name to be the primary domain name and use domain forwarding for any other domains you want to lead to your storefront. For a customer, typing in any of the domains will bring them to the storefront, but they will see the domain change to the primary domain in their browser address bar.


Can I access more than one store under a single control panel? It is not possible to access more than one BigCommerce store through a single control panel. However, you can switch between multiple stores from the Control Panel above the Log Out section.


Forwarding Secondary Domains

These instructions assume you have purchased a root domain, additional root domains, and subdomains from the same registrar (the company you bought your domain from). Before starting, determine which of your root domains or subdomains will be the primary domain. This will be the domain that the others will redirect to.

1. Apply the primary domain to your store. This will make the store and control panel under that domain.

2. Go to your registrar control panel and point your primary domain. The method you use to point your domain will be different depending on whether your domain is a root domain (e.g. or a subdomain (such as

3. You will now want to forward your remaining domains to the primary domain. Because instructions will vary for each registrar, we recommend calling your registrar and asking them to assist you with forwarding these domains.


What’s the difference between pointing a domain and forwarding a domain? Pointing a domain is a general term for updating the DNS records for a domain to bring the user to a third-party host. Forwarding a domain is a specific process that brings the user from one domain to another, regardless of the web host.
