Squarespace to Shopify: every URL changes

Short answer: the data is small and moves easily — Squarespace stores are rarely large. The risk is entirely in URLs. Squarespace uses /shop/p/product-name and /blog/post-title; Shopify uses /products/handle and /blogs/news/handle. Every URL changes, and without a complete redirect map you lose the rankings you built. Budget most of the project for redirects and content, not for the import.

Squarespace builds beautiful sites and a limited store. Most people migrating have outgrown the commerce side: no real variant depth, thin app ecosystem, limited shipping and tax handling, no serious B2B or subscription options.

The move is straightforward. The way it goes wrong is always the same.

What actually transfers?

Two rows carry the risk: URLs and design.

Design is not a loss so much as a decision. Squarespace's visual polish is a real strength and people are attached to it. A Shopify theme can match it closely, but it is a rebuild, not a transfer, and pretending otherwise is how a migration runs three weeks over.

URLs are where rankings live.

The URL problem, specifically

Squarespace and Shopify structure URLs differently in every content type:

Note the last row. Even a plain page moves, because Shopify puts custom pages under /pages/. Your /about becomes /pages/about, and the old URL 404s unless you say otherwise.

Every inbound link, every ranking, every bookmark points at the old shape. A 404 is not a soft landing — Google drops the page, and the ranking goes with it.

The fix is a complete redirect map. One 301 from every old URL to its closest equivalent. Not to the homepage — a redirect to the homepage is treated as a soft 404 and passes nothing.

Build it from data, not memory:

1. Export every indexed URL. Google Search Console's Pages report and your Squarespace sitemap, combined and deduplicated.
2. Pull your analytics. Every URL that received a visit in the last twelve months, sorted by traffic. This catches pages the sitemap missed.
3. Match each one to its new destination. Product to product, post to post, page to page.
4. Decide about the unmatched. A discontinued product goes to its collection, not the homepage. A deleted page with no equivalent returns 410, deliberately.
5. Load them into Shopify before you switch DNS, under Online Store → Navigation → URL Redirects, or by CSV import for a large set.
6. Test with the real list. Request every old URL and check the status code. Not a sample.

We have written this up in more detail in the redirect map we use on every migration.

This is the difference between a migration nobody notices and one that halves your organic traffic for six months.

Step by step

1. Inventory what you have. Products, collections, pages, blog posts, forms, member areas, anything custom. Squarespace sites accumulate pages nobody remembers building.

2. Export. Products under Commerce → Inventory → Export. Orders and customers separately. Content under Settings → Import & Export, which produces WordPress-format XML.

3. Audit before importing. Same rule as any migration: do not move what you would not build today. Discontinued products, abandoned blog posts, pages that exist because of a campaign three years ago. Each one imported is a page competing for crawl attention.

4. Transform the product CSV. Squarespace's format does not match Shopify's. Variant rows, image columns and option naming all differ. Import ten products first and look at the result before running the file.

5. Build the theme. This is the longest task and the one to start early. Either a premium theme configured to match, or a custom build. Decide which before the rest of the work, because it sets the timeline.

6. Migrate content. Blog posts import from the XML. Pages are rebuilt — copy the content, lay it out in the new theme.

7. Build and load the redirect map. As above. Before DNS.

8. Set up commerce properly. Shipping profiles, tax regions, payment providers, notification emails. Squarespace handled some of this with fewer decisions; Shopify gives you more control and expects you to use it.

9. Test on the .myshopify.com domain. Real orders, real refunds, shipping rates to several destinations, every email template.

10. Switch DNS, then verify immediately. Redirects working, sitemap submitted in Search Console, analytics recording, checkout completing.

11. Watch Search Console for a month. Crawl errors and coverage are where a missed redirect shows up. Expect a dip in the first two to three weeks even with everything right; expect it to recover.

What do people get wrong?

Migrating everything. The urge to preserve is strong and usually wrong. A hundred products where forty sell means sixty pages diluting crawl attention.

Redirects after DNS. By the time you notice the 404s, Google has already crawled them. Load the map first.

Redirecting to the homepage. Treated as a soft 404. Passes nothing. Worse than a 404 in that it hides the problem from you.

Forgetting the blog. Blog posts are often the best-ranking pages on a Squarespace site, and they are the ones people forget to map because they are not commerce.

Rebuilding the design pixel for pixel. Squarespace's layout system differs enough that chasing an exact match costs more than it returns. Match the brand, not the grid.

Assuming customer passwords move. They do not, from any platform. Customers need to reset, so tell them in advance rather than letting them discover it at checkout.

Is it worth it?

If you are migrating for design, no. Squarespace's is excellent.

If you are migrating because the commerce side is blocking you — variants you cannot model, shipping rules you cannot express, apps that do not exist, subscriptions or B2B you cannot support — then yes, and the constraint will only get more expensive as you grow.

The execution risk is almost entirely the redirect map. Get that right and the rest is ordinary project work.
