Redirecting myshopify domain to custom domain

Technical Q&A

Topic summary

A store owner wants to migrate from their myshopify.com domain to a custom domain (store.com) without disrupting active paid advertising campaigns that link to the old URLs.

Main Concern:

  • Existing ads use myshopify.com URLs with significant budgets and good performance
  • Need to ensure old links continue working during and after migration
  • Want to avoid turning off ads or losing traffic

Proposed Solution:

  • Add the custom domain in Shopify settings, which will automatically update product and collection links to the new primary domain
  • Keep both domains in the Shopify Domains list to maintain automatic redirects from old URLs to new ones
  • This approach should preserve ad functionality without requiring manual URL updates

Status: The question appears answered with a straightforward technical solution, though the original poster has not confirmed implementation or results.

I’d appreciate some help :slightly_smiling_face:

We want to move our myshopify domain to a custom domain of ours so the main domain will be store.com instead of store.myshopify.com.

The thing is, we’re already running paid ads for some time, where the URL’s in the ads are from the store.myshopify.com domain.

I want to do this migration in a way that the old links will still work and we won’t have to turn off any ads, as a lot of them have a nice budget and are getting good results. So I want the main URL to be store.com, but the store.myshopify.com links still to work and redirect the customers to the new store.com domain.

It’s probably not an extremely complicated process, but I just don’t want to risk anything, given that we’re running paid ads on the current URLs already. If someone could guide me step by step, so that we make sure that we don’t do any silly mistakes, that would be great :slightly_smiling_face:

Hi,
By adding a new custom domain in Shopify, all product and collection links should automatically be updated for the new primary domain.
Also to ensure that old URLs still work and redirect customers to the new domain, you will want to keep both domains within your Shopify Domains list.
