Introduction

Platform migration is one of the riskiest SEO events a website can go through. Done poorly, it can wipe out years of search ranking progress overnight. Done properly, it can be a completely invisible transition to Google — and even an opportunity to improve. This guide covers exactly how we approach WooCommerceto-Shopify migrations for our clients, step by step.

Why Migrations Destroy Rankings (and How to Prevent It)

Most ranking drops during migrations happen for one of three reasons: broken 301 redirects (old URLs return 404 errors), missing canonical tags, or lost internal link equity. Google values URL consistency. When a URL that had 200 inbound links suddenly returns a 404, all of that link equity is lost. The solution is meticulous premigration URL mapping and a comprehensive 301 redirect plan.

Step 1: Audit Your Existing WooCommerce URLs Before You Begin

Before touching a single page of your new Shopify store, export every indexed URL from your
WooCommerce site. Use Google Search Console to export all pages receiving organic impressions, and
Screaming Frog to crawl your entire site. The output should be a spreadsheet of every URL that needs a
corresponding redirect on the new platform. This step is non-negotiable.

Step 2: Map Every Old URL to Its New Shopify Equivalent

Create a mapping document: old WooCommerce URL in column A, new Shopify URL in column B. Pay
attention to URL structure differences. WooCommerce uses /product/product-name/ while Shopify uses
/products/product-name/. Category URLs (/product-category/name/) become collections (/collections/name/).
Each difference needs a redirect.

Step 3: Build the New Shopify Store in Parallel

Never migrate directly — always build the new Shopify store in a separate environment while the
WooCommerce store remains live. Migrate product data using a tool like Matrixify or LitExtension. Recreate
meta titles, meta descriptions, and alt text for every page and product. Set up canonical tags. Do not launch
until the new store has been fully QA’d.

Step 4: Implement 301 Redirects on Shopify

Shopify has a built-in URL redirect tool (Online Store > Navigation > URL Redirects). Upload your full redirect
mapping via CSV. Every single old URL must redirect to its new equivalent — not to the homepage.
Redirecting everything to the homepage destroys link equity just as effectively as a 404.

Step 5: Post-Migration Checks

After launch: submit your new sitemap in Google Search Console, run a full Screaming Frog crawl to check
for 404 errors, verify every priority redirect is working correctly, and monitor ranking positions daily for the first
two weeks using a rank tracker. Expect minor fluctuation in the first 2-4 weeks — this is normal. If positions
drop significantly and do not recover by week 8, there is likely a redirect or canonical issue to investigate.
