On WordPress
Use the WPML or Polylang plugin — both generate correct hreflang tags automatically when you translate pages. Don't set hreflang tags manually unless you know the full specification.
On Shopify
Shopify Markets automatically adds hreflang tags when you sell to multiple regions. If using a custom international setup, check the Translate & Adapt app.
