Migrating from PrestaShop to Shopify without losing your SEO
The real pitfalls of an e-commerce migration: 301 redirects, URL structure, sitemap, and how to make the switch without losing your traffic.
I have helped several merchants migrate their PrestaShop store to Shopify. Every time, the same questions come up: is it really worth it? And above all, will I lose my search rankings?
The short answer: yes, it is worth it. And no, you do not lose your SEO, as long as you do not improvise.
The signs that PrestaShop is holding you back
PrestaShop is a solid platform. But it demands time, technical knowledge, and a regular maintenance budget.
Here are the signals I see in merchants who start looking for an alternative:
- Updates break modules. A payment or shipping module that stops working after a minor update, with no one left to maintain it.
- The store slows down without intervention. Hosting starts to limit things, images are not optimised, and the Lighthouse score drops.
- Every evolution costs money. Changing a display element or adding a feature always goes through a PHP developer.
- The team is not autonomous. Adding a product, managing stock, creating a promotion, simple tasks that become sources of friction.
If three of these points ring true, the question of migrating is worth asking seriously.
What Shopify changes concretely
Shopify is not perfect, but it structurally solves most of the problems listed above.
Hosting is included. Updates are automatic. There is no module compatibility to verify, Shopify App Store apps are maintained by their publishers and certified by Shopify.
What changes day to day:
- Zero server management. No cPanel, no manual backups, no SSL certificate to renew.
- The team becomes autonomous. The merchant interface is designed for non-developers. Adding a collection, editing prices, managing promotions, all doable without touching code.
- Performance is stable by default. Shopify themes are optimised for mobile and load fast without any special configuration.
- The app ecosystem is extensive. Customer reviews, loyalty programmes, ERP connectors, most needs are covered without custom development.
The trade-off: Shopify is a closed system. You cannot modify the core, and some complex business logic may require custom development.
The 3 mistakes that kill your SEO during a migration
This is where most migrations go wrong. Not because of Shopify, but because of insufficient preparation.
Mistake #1: not setting up 301 redirects.
PrestaShop and Shopify have fundamentally different URL structures. A product that was accessible at /en/men/t-shirts/white-t-shirt-32.html ends up at /products/white-t-shirt on Shopify.
Without a redirect, Google considers the old page to have disappeared. The lost position takes weeks or months to rebuild.
Best practice: before launch, export all URLs that have traffic from Google Search Console, and prepare a comprehensive 301 redirect file.
Mistake #2: changing the URL structure without a strategy.
Shopify imposes certain structural constraints (/products/, /collections/). Rather than trying to reproduce PrestaShop URLs exactly (which is often impossible), the goal is to build a coherent new structure and ensure every old URL redirects to its logical equivalent.
Changing URLs without a redirect plan is the fastest way to lose organic rankings.
Mistake #3: forgetting the sitemap and recrawl.
On the day after launch, the new Shopify sitemap must be submitted in Google Search Console. Without this, Google takes several weeks to discover the new URLs on its own.
Monitoring crawl errors for the six weeks following launch is non-negotiable, that is the period when missing redirect issues surface.
How to organise a clean transition
A successful migration is not improvised the day before launch. Here is the sequence that has worked on the projects I have managed:
- Audit the strategic URLs. Identify pages that generate organic traffic in Search Console. These are the ones that must be redirected without exception.
- Prepare the redirect file before touching production. Shopify allows importing a CSV file of redirects. Prepare it offline, validate it, then import it all at once.
- Do not shut down the old site too quickly. Keep PrestaShop accessible while Google crawls the new URLs and processes the redirects, usually two to four weeks after launch.
- Verify critical redirects right after go-live. A tool like Screaming Frog can crawl the old URLs and verify that the 301s respond correctly.
- Monitor Search Console actively. For at least one month, watch impressions, clicks, and coverage errors. A sudden drop is usually a sign of a missing redirect.
A clean migration is invisible in organic traffic. The goal is zero disruption, and it is perfectly achievable with the right preparation.
