301 Redirects in Shopify Migrations: How to Protect Your SEO Traffic

Migrating an ecommerce store to Shopify involves much more than moving products, choosing a theme, and configuring payments. One of the most important parts of the migration happens behind the scenes: preserving the URLs that customers and search engines already know.

An established store may have hundreds or thousands of product, category, content, and landing page URLs indexed by search engines. Some of those pages may generate organic traffic, have external backlinks, or appear in customers' bookmarks.

Because Shopify's URL structure is likely to differ from the platform you are leaving, those existing URLs need to be considered before the new store goes live. Shopify itself recommends setting up URL redirects during a migration so that visitors reaching old links are sent to the appropriate pages instead of encountering errors.

Why are 301 redirects important during a Shopify migration?

A 301 redirect tells browsers and search engines that a URL has permanently moved to another location.

Imagine an existing product is available at:

/men/sunglasses/model-x

After migration, its Shopify URL becomes:

/products/model-x

If the old URL simply disappears when the domain is pointed to Shopify, anyone visiting that address may encounter a 404 page.

Instead, the migration should map:

/men/sunglasses/model-x
→ /products/model-x

The same principle applies to collections, blog articles, informational pages, and important campaign landing pages.

Redirects are therefore not just about reducing 404 errors. They are part of the process of transferring an existing website structure into the new Shopify architecture while maintaining continuity for users and search engines.

Shopify specifically recommends creating redirects for important pages when migrating from another platform and checking that high-traffic pages continue to reach the appropriate destination.

Build the URL inventory before the new store launches

A common migration mistake is waiting until the Shopify store is almost ready before looking at the old website's URLs.

URL mapping should start much earlier.

The first step is to build an inventory of the existing site's important URLs. This usually includes:

• product pages,
• category or collection pages,
• blog articles,
• informational pages,
• campaign and landing pages,
• pages receiving organic traffic,
• URLs with valuable external backlinks.

The next step is to determine where each URL should lead in Shopify.

A simple migration document might contain:

Old URL → New Shopify URL

For example:

/category/sunglasses
→ /collections/sunglasses

/product/model-x.html
→ /products/model-x

/blog/sunglasses-guide
→ /blogs/guides/sunglasses-guide

This mapping becomes a useful reference for developers, SEO teams, and ecommerce managers throughout the migration.

Don't redirect everything to the homepage

When an old page does not have an exact equivalent in the new store, sending every missing URL to the homepage can seem like the easiest solution.

It usually isn't the most useful one.

If an old product has been discontinued, there may be a closely related replacement product or relevant collection.

If several old categories have been consolidated into one new Shopify collection, those URLs may reasonably point to the consolidated collection.

The guiding principle should be:

The intent of the old page should match the destination as closely as possible.

Redirect mapping should therefore be treated as an information architecture task, not simply a technical spreadsheet exercise.

Understand Shopify's redirect limitations

Shopify allows merchants to create URL redirects from the Admin and import or export redirect lists using CSV files. This is particularly useful for larger migrations where manually creating hundreds or thousands of mappings would be inefficient.

However, Shopify redirects have some important constraints.

According to Shopify's current documentation, redirects can only originate from URLs that are broken and return an error such as a 404. If the source URL still loads a valid page, the redirect won't work.

Shopify also reserves certain paths. For example, URLs beginning with paths such as /apps, /cart, /orders, /services, or /shop cannot be redirected in the normal way. Fixed Shopify paths including /products, /collections, and /collections/all also have restrictions.

These limitations matter when migrating from platforms with very different URL structures.

They are another reason to examine the existing URL architecture before finalizing the Shopify structure.

Pay attention to query strings and legacy URLs

Older ecommerce platforms often generate URLs containing parameters or query strings.

For example:

/category?id=52&brand=example

or:

/products.html?category=12

Shopify notes that URLs containing query strings or certain special characters might not behave as expected with its standard redirect functionality.

For this reason, a migration URL inventory should not rely exclusively on the old site's sitemap.

Depending on the project, it can also be useful to review sources such as:

Google Search Console, analytics landing pages, backlink data, the existing platform's URL database, and historical crawl data.

Sometimes the URL carrying SEO value is not the clean URL currently shown in navigation, but an older address that has accumulated links and search visibility over several years.

Avoid unnecessary redirect chains

Another issue to watch for is redirect chains.

Instead of:

Old URL → Intermediate URL → New Shopify URL

the preferred structure is usually:

Old URL → Final Shopify URL

This becomes especially relevant when a business has already migrated between ecommerce platforms in the past.

Importing an old redirect table without reviewing it can preserve unnecessary intermediate steps.

A Shopify migration is therefore a useful opportunity to clean up the redirect structure and point legacy URLs directly to their final destinations wherever practical.

URL changes inside Shopify also need attention

Redirect planning is not limited to migrations from another ecommerce platform.

Changing product, collection, page, or article URLs after a Shopify store is already live can create the same underlying issue.

For example, if product naming conventions or handles are changed as part of a large catalog restructuring, old URLs may need to be redirected to their new locations.

For stores with large catalogs, this is another reason to establish sensible naming and URL conventions before launch rather than repeatedly changing handles after pages have been indexed.

Test redirects before considering the migration complete

Creating the mapping file is only part of the job.

The redirects also need to be tested.

For important URLs, verify that:

• the old URL reaches the intended destination,
• the destination page loads correctly,
• the redirect does not lead to an unrelated page,
• unnecessary redirect chains haven't been introduced,
• high-value legacy URLs aren't returning 404 errors.

Shopify's migration guidance explicitly recommends confirming redirects after launch by visiting the original URLs and checking that they reach the expected Shopify pages.

For Shopify Plus launches, Shopify also specifically includes creating or importing 301 redirects in its launch checklist to help prevent old links from becoming dead links.

Continue monitoring after launch

A migration isn't finished the moment the domain points to Shopify.

During the first weeks after launch, it's useful to monitor 404s, organic landing pages, and the performance of important pages.

Previously unknown legacy URLs may surface during this period. When an old URL still has meaningful traffic or external links, an appropriate redirect can be added.

Search engines also need time to crawl and understand the new site structure. Shopify automatically generates and updates a sitemap.xml file for products, collections, pages, and blog posts, which can be submitted through Google Search Console.

The goal is not necessarily to eliminate every possible 404 on a domain that may have existed for many years.

The priority is to make sure valuable legacy URLs don't become dead ends simply because the ecommerce platform changed.

A practical migration sequence

For most Shopify migration projects, the URL work can be organized into a straightforward sequence:

Crawl the existing site → Identify valuable URLs → Define the new Shopify URLs → Build the redirect mapping → Import redirects → Launch → Test → Monitor

Treating redirects as part of the migration itself, rather than a last-minute SEO task, makes the process much easier to control.

Digimaps perspective

In Shopify migration projects, we prefer to map the existing URL structure while products, collections, and content are being reorganized. This makes it possible to test redirects before and immediately after go-live instead of discovering important missing URLs later.
