Great question. This is something which is possible to do and natively from the Shopify admin. From what you have described it sounds like you are looking for a URL redirect. URL redirects can be used to redirect traffic from one web page to another. In saying that you would need to own and have both URL domains connected to your store. Once you have both domains connected, you can apply the URL redirect. You can do this by taking the following steps:
From your Shopify admin, go to Online Store > Navigation.
Can you share the message or a screenshot of what it is showing you when it won’t accept the redirect, please?
It’s difficult to know why this might not be working without seeing the error message.
In the meantime, there are also some redirect apps in the Shopify App Store which might also be worth looking into. One of them is called Easy Redirects and has a free plan that you can see here.
Is there a different way to get the second domain to point to a page on the main domain? Both my domains are connected to my account. I would love to hear your response.
I’m wondering if this is because of the following:
Only broken URLs should be redirected. Broken URLs might load a “page not found” placeholder message, or “404” might appear somewhere on the page or in the page title. If the URL still loads a valid webpage, then the URL redirect won’t work.
I am also having the same issue and no one at Shopify Plus Support seems to understand the issue nor the solution.
The URL Redirects in the admin only redirect FROM your primary domain. The question is how to set the “redirect from” specifically from the secondary domain.
