Key takeaways
- Ecommerce migration SEO starts weeks before launch, with a full crawl and benchmark.
- Map every product, category and content URL to its new address with a 301 redirect.
- Carry over titles, descriptions, content, reviews and structured data.
- Monitor 404s, rankings and revenue closely for the first few months.
Why migrations go wrong
Moving an online store to a new platform, for example from WooCommerce or Magento to Shopify, changes almost every URL on the site. If old product and category addresses aren't redirected properly, the rankings and links they've earned disappear, and so do the sales they bring.
Good ecommerce migration SEO is mostly careful preparation. Follow the checklist below, and treat redirects as a core part of the project, not an afterthought on launch day. If you're still choosing a platform, read our comparison of WordPress vs Shopify first.
Before the migration: benchmark everything
- Crawl the current site to get a full list of URLs: products, categories, filters, blog posts and pages.
- Export performance data: top pages by organic traffic and revenue from Google Analytics 4, and top queries and pages from Search Console.
- List your most-linked pages, so you know which URLs carry the most authority.
- Record current rankings for your most valuable keywords.
- Save on-page SEO: titles, meta descriptions, headings, product descriptions and structured data.
Don't change everything at once. Migrating platform, redesigning and rewriting content in one go makes it impossible to tell what caused any drop. Keep content and structure as stable as possible during the move.
Map every URL
Create a spreadsheet with every old URL and its new equivalent. Platforms often force new URL patterns, for example:
| Page type | Old (example) | New on Shopify (example) |
|---|---|---|
| Product | /shop/blue-wool-scarf/ | /products/blue-wool-scarf |
| Category | /product-category/scarves/ | /collections/scarves |
| Blog post | /how-to-wash-wool/ | /blogs/news/how-to-wash-wool |
| Information page | /delivery-information/ | /pages/delivery-information |
- Redirect each old URL to the most relevant new page, not the home page.
- For discontinued products, redirect to the closest product or category.
- Avoid redirect chains: point old URLs straight to their final destination.
During the build
- Block search engines from the staging site with password protection.
- Carry over on-page SEO: titles, descriptions, headings, product copy and image alt text.
- Keep product reviews and migrate them to the new platform where possible.
- Add structured data for products, prices, availability and breadcrumbs.
- Set canonical tags to manage duplicate URLs from filters and product variants.
- Check speed on key templates before launch.
- Set up tracking: GA4 ecommerce events, Search Console and conversion tags.
Remember to remove the block at launch. One of the most common migration mistakes is launching with the staging site's noindex setting or password protection still in place.
Launch day checklist
- Upload and test redirects for a sample of your most important URLs.
- Check that robots.txt and noindex settings allow crawling.
- Submit the new XML sitemap in Search Console.
- Test checkout, payment, emails and tracking with a real order.
- Update internal links, ads, email templates and Google Merchant Center product feeds.

Get my free audit After launch: monitor closely
- Daily for the first two weeks: 404 errors, crawl errors in Search Console and checkout performance.
- Weekly for three months: organic traffic, rankings and revenue compared with your benchmark.
- Keep redirects in place long-term, ideally permanently, because old links keep sending visitors and authority.
Some movement in rankings is normal for a few weeks while Google processes the changes. A steady or sharp decline is a sign something is wrong, usually missing redirects or lost content. Our website redesign SEO checklist and technical SEO guide cover the related checks.
Common migration mistakes
- Redirecting every old URL to the home page.
- Dropping product descriptions, reviews or category content.
- Launching with noindex or password protection still on.
- Changing platform, design and URLs at the same time with no benchmark.
- Removing redirects after a few months.
Ecommerce migration FAQs
Will I lose rankings when I migrate?
Some short-term movement is common, but a well-planned migration with complete redirects and preserved content usually recovers quickly, and often improves once the new site is faster.
How do I add redirects on Shopify?
Shopify has a built-in URL redirects tool where you can add redirects one by one or import them in bulk from a CSV file.
How long should I keep redirects?
Ideally permanently. Old links on other websites, bookmarks and emails will keep using your old URLs for years.
When is the best time to migrate?
Choose a quieter trading period, never just before your peak season, and avoid launching on a Friday, so your team is available to fix any issues.
The bottom line
Ecommerce migration SEO comes down to preparation: benchmark everything, map every URL to its best new match, preserve your content and reviews, launch carefully and monitor closely. Do that, and your new platform can keep, and grow, the rankings and sales you've earned.
