Shopify theme → Headless Next.js storefront · Updated
Shopify to Headless Next.js Migration
A Shopify to headless Next.js migration keeps Shopify for products, checkout and orders and replaces the theme storefront with a Next.js frontend that reads the catalog through Shopify’s APIs. Nothing about the commerce data has to be exported; the work is the storefront, the content pages and the URL plan.
Who this migration is for
- Stores whose theme has hit a ceiling on speed, custom pages or content, while checkout and fulfillment work fine.
- Brands that publish guides, comparisons and buying content and want it to rank and be cited alongside the catalog.
- Teams that want product, collection and content pages served as HTML to search engines and AI agents.
What Shopify theme lets you export
Taken from the vendor’s own documentation, linked below. We do not promise an export the platform does not provide.
Documented export
- Shopify documents a products CSV export, used for "creating backups, moving products to a new store" and bulk editing; it can cover all products or a filtered set.
- In a headless build the catalog is not exported at all; it stays in Shopify and is read live through the API.
Not exported or stops working
- Per Shopify, product images "aren’t included in the CSV file", and SEO title and description columns are blank unless they were customized.
- Per Shopify, files with more than 100 variants on a product are emailed rather than downloaded, and sorting the CSV in a spreadsheet can disassociate variants and image URLs.

What we rebuild rather than import
- The storefront: product, collection, search and cart pages in Next.js, reading Shopify through its Storefront API, with checkout still on Shopify.
- Content pages, blogs and landing pages move into a headless CMS so merchandising and editorial content share one model.
- Design and templates. A migration is a rebuild of the presentation layer; we do not try to convert a theme or builder output into React.
- Forms, lead routing and spam protection, wired to your CRM or inbox and tested end to end.
- Structured data: one Organization node, Service and FAQ markup that mirrors the visible page, validated before launch.
- Analytics, consent and conversion events, so the first month after cutover is measurable.
Want to know what your Shopify theme site would keep?
The free audit inventories your URLs and traffic and tells you what a migration would have to preserve.
How rankings are preserved
Shopify theme-specific notes first, then the eight steps every migration follows.
- Shopify URL conventions (/products/handle, /collections/handle, /pages/handle, /blogs/name/handle) are kept so product and collection pages need no redirects.
- Shopify-generated duplicates such as /collections/name/products/handle are canonicalized to the single product URL.
- Product structured data is generated from live catalog data, so price and availability in schema always match the page.
- 1
Inventory every URL that exists and every URL that earns
Crawl the live site, pull the sitemap, and export the Search Console Pages and Performance reports. The union is the redirect map input; the Performance rows decide what must be preserved exactly.
- 2
Decide the new URL structure before building
Keep paths where they are sane. Change them only where the old structure was a liability, and record the change in a one-to-one map. No wildcard redirects to the homepage.
- 3
Carry metadata field by field
Titles, descriptions, canonicals, Open Graph and existing structured data are exported with the content and loaded into the new pages, then diffed against the live site.
- 4
Rebuild structured data from one identity
One Organization node with the real address, phone and founder; Service, Article and FAQ markup that mirrors the visible page; validated before launch.
- 5
Preserve internal links and images
In-body links are rewritten to the new paths rather than left to bounce through redirects. Images are self-hosted so nothing depends on the old platform staying up.
- 6
Test the redirect map against the inventory
Every old URL is requested and must return one 301 to a 200 page. Chains, loops and 404s fail the launch.
- 7
Cut over and submit
DNS switch, new sitemap submitted, IndexNow ping, and a full crawl of the new site within the first day.
- 8
Monitor index coverage for a month
Indexed versus submitted, crawl errors, redirect-reported URLs and the top earning queries are checked weekly. A migration is done when coverage matches or beats the old site, not when the new one is live.
Why coverage is the finish line: our index coverage research. How AI agents read the result: which AI crawlers visit your site.
Why businesses make this move
- Checkout, payments, taxes and fulfillment stay on Shopify, which is the part of the platform worth keeping.
- Server-rendered HTML. Search engines and the search-type AI agents read the page as delivered, not after a browser runs scripts.
- No plugin or app layer to patch, which removes a class of security and performance regressions.
- Content modeled as data, so the same facts feed pages, schema and llms.txt without drifting apart.
How the engagement runs
| Phase | What happens |
|---|---|
| Discovery | Goals, constraints, what the current platform does well, what it blocks. Access to analytics, Search Console and the admin. |
| Inventory | URL list, content audit, export of everything the platform allows, capture of everything it does not. |
| Content model and design | Document types and fields, page templates, components. Approval before build. |
| Build | Next.js frontend, CMS setup, content load, forms, schema, analytics and consent. |
| Redirect map and QA | Old to new URL map, automated redirect test, page-by-page content diff, accessibility and performance checks. |
| Cutover | DNS switch, sitemap and IndexNow submission, first crawl, old platform kept read-only until coverage is confirmed. |
| Monitoring | Weekly index coverage, crawl errors and query checks for a month; fixes shipped as found. |
Common questions
Do I lose Shopify checkout or apps?
Checkout stays on Shopify. Apps that run inside the theme (reviews widgets, upsells) are reimplemented or replaced; apps that run in the admin (shipping, inventory, email) are unaffected.
Do I need to export my products?
Not for a headless storefront. The catalog stays in Shopify and the Next.js site reads it live. A CSV export is still useful as a backup, with the documented caveats that images are not included and SEO fields may be blank.
Will product URLs change?
No. The Shopify URL conventions are preserved on the new storefront, so product and collection pages keep their paths and their rankings.
Is headless worth it for a small store?
Usually not for a store that is only a catalog. It is worth it when content, speed and custom pages are the growth lever and the theme is the constraint. We say so in the audit if it is not.
