Preserving SEO During an E-commerce Migration
301 redirects are the most critical element in a migration to Shopify. They signal to search engines that a page has permanently moved to a new URL, preserving authority, rankings and organic traffic.
Without properly implemented redirects, a migration can result in significant loss of visibility.

Search engines transfer the authority of the old page to the new one.
