Switching ecommerce platforms feels risky. You have spent years building traffic, earning backlinks, and climbing search rankings. The last thing you want is to watch all of that disappear the moment you move your store.
Here is the good news. A BigCommerce to Shopify migration does not have to cost you your rankings. With the right plan, you can move your products, content, and customers while keeping your SEO equity intact.
This guide walks you through every step. You will learn how to prepare, what to migrate, how to protect your URLs, and how to verify everything after launch.
Why Brands Switch from BigCommerce to Shopify
BigCommerce is a capable platform. But many growing brands find that Shopify fits their needs better as they scale.
Shopify offers a larger app ecosystem, a cleaner admin experience, and a theme marketplace that makes design updates simple. It also has stronger support for conversational commerce and marketing automation.
Before you commit, it helps to understand the differences. Our detailed Shopify vs BigCommerce comparison breaks down pricing, features, and scalability side by side.
Here is a quick snapshot of why brands make the switch.
| Factor | BigCommerce | Shopify |
|---|---|---|
| App ecosystem | Smaller marketplace | 8,000+ apps |
| Theme selection | Limited free themes | Large free and paid library |
| Checkout control | More flexible on lower tiers | Highly optimized, one-page checkout |
| Learning curve | Steeper for beginners | Friendly and intuitive |
| Payment options | No transaction fees | Fees unless using Shopify Payments |
If you notice slow growth, rising costs, or clunky workflows, those may be signs your platform is holding you back.
Understanding the SEO Risk Before You Start
Every migration carries SEO risk. When you change platforms, your URL structure, page speed, and internal links can all shift.
Search engines index your existing pages. If those pages break or redirect poorly, you lose ranking signals. That means less traffic and fewer sales.
The key is to treat SEO as a core part of the move, not an afterthought. Our guide on how to preserve SEO rankings when migrating to Shopify covers the principles in depth.
In short, you want to:
- Keep the same URL slugs where possible
- Redirect old URLs that must change
- Preserve title tags and meta descriptions
- Maintain your content and heading structure
- Retain internal links and image alt text
Step 1: Audit Your Current BigCommerce Store
Start by taking inventory of everything you have. You cannot protect what you do not track.
Export a full list of your URLs using a crawler like Screaming Frog. Record your top-performing pages by traffic and backlinks.
Pull these items from BigCommerce:
- Product pages and variants
- Category and collection pages
- Blog posts and landing pages
- Customer accounts and order history
- Meta titles, descriptions, and alt text
- Redirects already in place
Note which pages drive the most organic traffic. These deserve the most careful handling during your move.
Step 2: Map Your URL Structure
URL mapping is the most important SEO step in any BigCommerce migration guide. Get this wrong and rankings drop fast.
BigCommerce and Shopify format URLs differently. For example, Shopify adds prefixes like /products/ and /collections/.
Here is a typical comparison.
| Page type | BigCommerce URL | Shopify URL |
|---|---|---|
| Product | /blue-cotton-shirt/ | /products/blue-cotton-shirt |
| Category | /mens-shirts/ | /collections/mens-shirts |
| Blog post | /blog/post-title/ | /blogs/news/post-title |
Because the structures differ, you will need 301 redirects. These tell search engines that a page has permanently moved and pass most of the ranking value to the new URL.
Build a spreadsheet with two columns: old URL and new URL. This becomes your redirect map.
Step 3: Choose the Right Shopify Plan
Pick your plan before you migrate so you set up the store correctly from the start.
Your choice depends on your sales volume, staff accounts, and need for advanced reporting. Our breakdown of Shopify Basic vs Advanced vs Plus helps you compare features.
If you are still weighing options, read our guide on which Shopify plan is right for your business. Larger brands handling heavy traffic may also want to review Shopify Plus vs Salesforce Commerce Cloud.
Step 4: Export and Import Your Data
Now you move the actual store data. Shopify supports CSV imports for products, customers, and more.
Export your BigCommerce catalog as CSV files. Then reformat them to match Shopify import templates. Column headers must line up, or the import will fail.
Migrate these data types in order:
- Products and variants
- Collections and categories
- Customer records
- Blog posts and pages
- Order history
For large catalogs, manual CSV work gets slow. Many brands use migration apps or hire a specialist. If your store runs on complex API integrations, our piece on migrating from REST to GraphQL explains how data layers can shift during a move.
Always test a small batch first. Import ten products, check the result, then scale up.
Step 5: Recreate Your Design and Content
Your new store should feel familiar to returning customers. A fresh design is fine, but keep your brand identity consistent.
Shopify offers hundreds of themes. Browse our roundup of the best Shopify themes to find one that fits your niche.
Not sure how to pick? Our guide on choosing the right Shopify theme walks through layout, speed, and feature considerations.
Once you pick a theme, you may need custom tweaks. The Shopify Liquid tutorial shows how to edit your theme safely without breaking it.
When you rebuild pages, keep your heading structure and content intact. Copy your H1 tags, body copy, and internal links exactly. This protects the on-page signals search engines already trust.
Step 6: Implement Your 301 Redirects
This is where you protect your hard-earned rankings. Redirects send both users and search bots from old URLs to new ones.
Shopify lets you add redirects under Online Store > Navigation > URL Redirects. For bulk uploads, use a CSV file or a redirect app.
Follow these rules:
- Redirect every old URL to its closest match
- Never redirect to a generic homepage
- Avoid redirect chains where one URL points to another that redirects again
- Test each redirect after launch
If you cannot find an exact match, redirect to the most relevant category or product. A close match keeps more value than a dead end.
Step 7: Preserve On-Page SEO Elements
Your redirects handle the technical side. Now focus on the content signals.
Transfer these for every page:
- Title tags
- Meta descriptions
- Image alt text
- Structured data and schema
- Canonical tags
Shopify generates some SEO fields automatically, but you should review them. Edit the title and description for each key page so they match your originals.
Do not forget your blog. Search engines value fresh, relevant content. If you publish helpful posts like guides on Shopify influencer marketing or selling on Shopify without inventory, keep those live and indexed.
Step 8: Set Up Payments and Checkout
Checkout affects both conversions and trust. Set it up before launch day.
Shopify Payments is the native option and avoids extra transaction fees. But some brands prefer third-party gateways. Our comparison of Shopify Payments vs Stripe helps you decide.
Test the full checkout flow. Place a real order, apply a discount code, and confirm the confirmation email sends correctly.
Step 9: Rebuild Marketing and Email Flows
Your email list is a major asset. Make sure your flows continue without a gap.
Export subscribers from BigCommerce and import them into your email tool. Then rebuild your automations.
Shopify works with many platforms. If you are choosing one, read our Klaviyo vs Mailchimp for Shopify comparison or our Shopify Email vs Mailchimp breakdown.
You can also automate campaigns using AI-powered email personalization to recover the momentum you had before the move.
Step 10: Test Everything Before Launch
Do not flip the switch until you have tested the full store.
Run through this pre-launch checklist:
- All products imported with correct prices and images
- Collections display properly
- Redirects point to the right pages
- Checkout and payment work end to end
- Mobile layout looks clean
- Site speed is acceptable
- Search Console and Analytics are connected

Step 11: Launch and Point Your Domain
Once testing passes, update your DNS settings to point your domain to Shopify.
Keep the exact same domain. Changing domains during a platform move doubles your SEO risk. One change at a time is always safer.
After the domain propagates, your store goes live. Monitor it closely for the first few hours.
Step 12: Submit Your Sitemap and Monitor Rankings
Right after launch, submit your new Shopify sitemap to Google Search Console. The sitemap lives at yourdomain.com/sitemap.xml.
Then watch your performance daily for the first few weeks. Look for:
- Crawl errors
- 404 pages
- Sudden drops in indexed pages
- Ranking changes for top keywords
A small dip is normal right after migration. Google needs time to recrawl and process your redirects. If rankings do not recover within a few weeks, revisit your redirect map for gaps.
Common Migration Mistakes to Avoid
Even careful brands slip up. Watch out for these errors.
- Skipping redirects for low-traffic pages that still hold backlinks
- Redirecting everything to the homepage
- Forgetting to transfer meta data
- Launching without testing checkout
- Ignoring mobile performance
- Not connecting analytics before launch
Avoid these and you protect most of your ranking value.
