Shopify's auto-redirect default
When you change the URL handle on a product, collection, page, or blog post while the resource is published, Shopify automatically creates a 301 redirect from the old handle to the new one. The redirect is added to Online Store > Navigation > URL Redirects on save and fires immediately. This is the single most useful default in Shopify SEO — the same handle change on WooCommerce, BigCommerce, or Magento would require a manual redirect.
The unpublish-republish trap
The auto-redirect only fires when the published status is preserved through the handle change. If you unpublish the resource first, change the handle, then republish, no redirect is created — and the old URL returns 404. This catches owners who follow the intuitive sequence: 'I want to safely change this URL, so I'll take it offline first.' That intuition is wrong on Shopify. The right move is to change the handle while it's still live.
The safe-sequence checklist
To change a handle without breaking SEO: keep the resource published throughout. Open the resource. Click Edit website SEO. Change only the URL handle field. Save. Verify the new redirect appears in URL Redirects under 'Created automatically'. Test the old URL with curl -I — it should return HTTP 301 with the new URL in the Location header.
Avoiding redirect chains
If you change a handle three times in a row (a → b → c → d), Shopify creates three redirects: a → b, b → c, c → d. A user requesting URL 'a' is 301'd three times before reaching 'd'. Google's redirect guidance recommends a maximum of five hops in a chain, but the cleanest SEO outcome is always a single hop. After every handle change beyond the first, edit the earlier redirects to point directly to the current final URL.
When to actually change a handle (and when not to)
Change a handle when: the original was auto-generated and ugly (e.g. /products/copy-of-red-dress); the product name changed materially (a rebrand); a typo needs fixing; or you're consolidating SKUs and the new handle communicates the consolidated identity better. Don't change a handle for: minor product description tweaks; cosmetic SEO improvements that don't change meaning; or to add keywords the handle 'should' have. The handle is rarely the constraint — title and description usually are.
