In this lesson, we'll redirect all traffic to a primary domain, which is a best practice for SEO. This means if you choose
www.example.com as your primary domain, then if a visitor navigates to
example.com (or any other domain you have connected to your site), they will end up on
Choose one of the following options to configure the primary domain.
Set a Primary Domain via the Dashboard
With a Primary Domain set at the platform level, all other domains will be pointed to your Primary domain at the root level. If you want to redirect secondary domains to specific pages on your site (for example,
newdomain.com/old-landing-page), do not set a Primary Domain. Instead use PHP redirects.
From the environment you want to set a primary domain for (typically Test or Live), navigate to Domains / HTTPS.
Ensure that all domains have been added and are listed.
In the Choose Primary Domain section, select the domain to which traffic should be redirected, and click Save Configuration.
Set a Primary Domain with Terminus
Install or upgrade to the latest version of Terminus.
Use Terminus to add the primary domain. In this example, replace:
my-sitewith your site name,
liveif you'd like to set it for a different environment
www.example.comwith your primary domain:
terminus domain:primary:add my-site.live www.example.com

Now that you're redirecting requests to a single, primary domain, it's the perfect time to configure a long-duration HSTS header, or set up an availability monitoring service to watch over your site like an automated hawk.
