Replatforming to Shopify without losing your SEO

Why migrations bleed traffic

Search engines rank URLs, not brands. Change the URL and, as far as Google is concerned, the page that earned five years of links and rankings no longer exists. Most migration traffic drops trace back to exactly this: URLs changed without one-to-one redirects, category content dropped in the rebuild, or internal links left pointing at the old structure.

The fear is legitimate — but it's a project-management problem, not a fate. One home & living retailer we moved to Shopify Plus held its rankings through the switch and came out 52% faster.

Start with a complete inventory

Before a single template is designed, assemble the full picture of what the current site has earned. Three sources, cross-referenced:

• A full crawl of the live site — every indexable URL, its title and its canonical.
• Search Console: every URL with impressions over the last 12 months, so seasonal pages aren't lost.
• A backlink export: the pages other sites link to are the ones that can least afford a broken redirect.

The redirect map is the project

Shopify imposes its own URL structure — /products/, /collections/, /pages/ — so most migrations can't keep old paths verbatim. That's fine: what matters is that every earning URL 301-redirects to its single best equivalent. Product to product, category to collection, guide to guide. A blanket redirect to the homepage tells Google the old pages are gone and their equity should be discarded.

Build the map as a reviewed spreadsheet, not a regex written the week of launch. Chains and loops count against you: redirect old → new in one hop.

Parity for the pages that rank

A redirect preserves the address; it doesn't preserve the reason the page ranked. For the templates that earn organic traffic, carry over title tags and meta descriptions, keep the category copy that gives collections something to rank for, and rebuild structured data (product, breadcrumb, FAQ) at parity or better. The redesign can change how it looks — not what it says.

Launch week, instrumented

Cut over at a quiet hour, submit the new sitemap immediately, and watch Search Console's coverage and 404 reports daily for the first month. Every 404 with impressions gets a redirect the same day. Expect a few weeks of index churn; what you should not see is a step-change drop in clicks. If rankings held through week four, the migration held.
