Switching platforms — or adding new suppliers to an existing Shopify store — sounds simple until you actually try to move a full product catalog over. Titles get mangled, descriptions come through as walls of unformatted text, images lose their alt tags, and search rankings that took months to build can quietly disappear within weeks of the move.

Migration mistakes are rarely about the platform itself. They’re about how the data gets moved. Here’s what actually matters if you want your product listings to survive the jump.

Why Product Migrations Go Wrong

Most catalog migrations fail in one of four predictable ways:

• Broken formatting. Bullet points, bold text, and spacing get stripped or garbled when moving between platforms, leaving pages that look unfinished.
• Lost metadata. Alt text, meta descriptions, and structured data often don’t transfer at all, which quietly tanks the SEO equity a product page had built up.
• Duplicate or thin content. Bulk imports frequently paste supplier descriptions verbatim across dozens of listings, creating duplicate content issues across your own catalog and against competitors selling the same items.
• No redirect mapping. Old product URLs that had backlinks and rankings get abandoned instead of redirected, sending that authority straight to a 404.

None of these are Shopify-specific problems — they show up in any migration. But Shopify’s ecosystem has made this easier to solve than it used to be, provided you approach it in the right order.

A Migration Checklist That Protects Your Rankings

1. Audit before you move anything

Pull a list of your current top-performing product URLs by organic traffic. These are the pages where a formatting mistake or missing redirect will actually cost you money — prioritize getting these exactly right.

2. Set up 301 redirects first, not last

Every old product URL that has any backlinks or search traffic needs a matching redirect to its new Shopify URL before the old page goes down. Mapping this after the fact means weeks of lost rankings while search engines figure out what happened.

3. Don’t import supplier text as-is

If your new listings are pulled straight from an AliExpress or wholesale supplier feed, rewrite the copy before it goes live. Beyond the SEO risk of duplicate content, generic supplier descriptions convert noticeably worse than pages written for your specific audience and brand voice.

4. Rebuild metadata deliberately

Meta titles, meta descriptions, and image alt text should be treated as part of the migration checklist, not an afterthought you’ll “get to later.” Search engines re-crawl and re-index migrated pages fairly quickly — what they find in that first pass matters.

5. Use tools built for bulk imports, not one-off entry

Manually rebuilding a catalog of a few hundred SKUs product-by-product is where most migrations stall out and get abandoned halfway through. Import and page-building tools designed specifically for moving listings into Shopify — eCopy is one example — handle formatting, structure, and bulk generation in a fraction of the time it takes to do it by hand, which matters most when a migration deadline is tight.

What to Check After the Migration Goes Live

• Spot-check your top 20 URLs in Google Search Console for crawl errors within the first week
• Confirm redirects are returning 301s, not 302s (temporary redirects don’t pass full link equity)
• Compare indexed page count before and after — a sharp drop usually means something broke during the move
• Re-check structured data with a rich results testing tool, since schema markup often gets dropped silently during platform transfers

The Bottom Line

A product catalog migration is one of the few moments where a store can lose months of accumulated SEO value in a single afternoon — or come out the other side stronger, with cleaner data and better-structured pages than it started with. The difference almost always comes down to sequencing: redirects before takedown, rewritten copy before bulk publish, and metadata treated as a requirement rather than a nice-to-have.
