BigCommerce has served many merchants well. But for a growing number of ecommerce businesses, its pricing model, app ecosystem limitations, and development complexity push them toward Shopify.
The switch itself is not complicated. What is complicated is doing it without losing the search rankings you have built over months or years. A poorly executed migration can wipe out organic traffic in days and take six to twelve months to recover.
This guide walks you through the complete bigcommerce to shopify migration process, with a specific focus on protecting your SEO from start to finish.
Why Merchants Switch from BigCommerce to Shopify
Before planning the migration, it helps to understand why so many merchants make this move and whether it is the right decision for your store.
| Factor | BigCommerce | Shopify |
|---|---|---|
| Monthly pricing model | Based on annual revenue, prices rise as you grow | Fixed monthly plans regardless of revenue |
| App ecosystem | Smaller marketplace, fewer integrations | 13,000+ apps, widest ecommerce ecosystem |
| Theme customization | Stencil framework, steeper learning curve | Liquid-based, easier for developers and agencies |
| Checkout customization | Limited to templates | Full checkout extensibility on Plus |
| Headless commerce | Supported | Shopify Hydrogen, industry-leading headless framework |
| Community and support | Smaller developer community | Largest ecommerce developer community globally |
| Platform stability | Solid but fewer updates | Continuous platform investment and new features |
For most merchants, the trigger is the revenue-based pricing model. BigCommerce charges more as you sell more, effectively penalising growth. Shopify’s fixed plans eliminate that uncertainty.
If you are still evaluating whether Shopify is the right long-term platform, our guide on why Shopify is the preferred choice breaks down the full commercial and technical case.
Understanding the SEO Risk in a Platform Migration
Changing platforms is one of the riskiest SEO events a website can undergo. It typically involves:
- A completely new URL structure
- Different HTML markup and page templates
- Changed internal linking patterns
- New sitemap and robots.txt files
- Potential downtime during the switchover
Every one of these can cause Google to re-evaluate your pages, drop rankings temporarily, or lose authority signals entirely if redirects are not set up correctly.
The good news is that with careful planning, you can execute a bigcommerce to shopify migration with minimal SEO impact and recover any temporary dips within a few weeks.
Phase 1: Pre-Migration Audit and Preparation
The most important work in a platform migration happens before you touch a single setting in Shopify.
Export All Indexed URLs from BigCommerce
Go to Google Search Console and export every URL currently indexed from your BigCommerce store. This is your master list of pages that need protecting.
Prioritise pages by:
- Organic traffic volume (highest priority)
- Backlinks pointing to them (highest risk if broken)
- Position for target keywords (most damaging to lose)
Do not guess. Pull the full data. A page getting 10 visitors per month from a single high-authority backlink may matter more to your rankings than a product page getting 500 sessions through paid traffic.
Record Your Current Rankings Baseline
Before migrating, document your rankings for your top 30 to 50 keywords. Use a rank tracking tool or a manual Google check. This baseline tells you exactly what to monitor after launch.
Audit Your BigCommerce URL Structure
BigCommerce and Shopify use different URL patterns:
| Page Type | BigCommerce URL Format | Shopify URL Format |
|---|---|---|
| Product | /product-name/ or /products/product-name | /products/product-name |
| Category | /category-name/ | /collections/collection-name |
| Static page | /page-name/ | /pages/page-name |
| Blog post | /blog/post-name/ | /blogs/news/post-name |
Map every BigCommerce URL to its Shopify equivalent in a spreadsheet before you start building. This redirect map is the most important document in your entire migration.
Phase 2: Build and Configure Your Shopify Store
Once your audit is complete, build your Shopify store while your BigCommerce store remains live. Your domain stays on BigCommerce until you are ready to switch.
Choose Your Shopify Plan
Your plan determines which features are available after migration. Most merchants migrating from BigCommerce land on the Shopify plan or Advanced plan depending on their revenue and reporting needs.
Our guide on Shopify plans and pricing covers every tier in detail. For high-volume merchants or those needing advanced checkout customisation and B2B features, compare Shopify vs Shopify Plus before committing.
Choose and Configure Your Theme
BigCommerce themes do not transfer to Shopify. You need to select a new Shopify theme and rebuild your storefront design.
Choose a theme that matches the visual style your customers already know. A dramatic change in design at the same time as a platform migration makes it harder to diagnose any conversion rate changes post-launch.
Our guide on how to choose the right Shopify theme covers performance, feature fit, and design factors to evaluate before selecting.
Phase 3: Migrate Your Data
Data migration covers four main categories: products, customers, orders, and content.
Option 1: Using a Migration App
The fastest approach for most stores is a dedicated migration tool:
| Tool | What It Migrates | Best For |
|---|---|---|
| Cart2Cart | Products, customers, orders, categories, blog posts | Mid-size stores |
| LitExtension | Full data migration with SEO redirect support | Stores prioritising SEO continuity |
| Matrixify | CSV-based bulk import with full control | Developers comfortable with spreadsheets |
LitExtension is worth considering specifically because it includes a URL redirect module that maps your BigCommerce URLs to your new Shopify URLs automatically, saving significant manual effort.
Option 2: CSV Import
Shopify accepts CSV files for products and customers. Export your BigCommerce product catalog and customer list, reformat the CSV to match Shopify’s required column headers, and import directly.
This gives you the most control but requires careful data cleaning before import. Product images, variant structures, and metafield data all need specific formatting.
What Migrates Well vs What Needs Manual Work
| Data Type | Migrates Automatically | Needs Manual Work |
|---|---|---|
| Product titles, descriptions, images | Yes | Light cleanup |
| Product variants and pricing | Yes | Check formatting |
| Customer email and address data | Yes | Passwords require reset |
| Order history (read-only) | Yes | No editing in Shopify |
| Blog posts and content pages | Partial | Review and re-enter formatting |
| SEO meta titles and descriptions | No | Must be re-entered manually |
| Product reviews | Partial (app-dependent) | May require manual re-import |
| BigCommerce app configurations | No | Rebuild in Shopify apps |
Phase 4: Protect Your SEO During Migration
This is the phase that separates a clean migration from a damaging one.
Set Up 301 Redirects Before Launch
Every URL on your BigCommerce store that receives organic traffic or holds backlinks needs a 301 redirect to its equivalent Shopify URL.
In Shopify, go to Admin > Online Store > Navigation > URL Redirects. Upload your redirect file using the bulk import tool.
Priority redirect order:
- All indexed product pages
- All indexed category/collection pages
- Homepage (if your domain changes)
- All blog posts with backlinks or traffic
- Static pages (About, Contact, FAQ, policies)
Never launch your Shopify store without completing your redirect map first.
Optimise Meta Titles and Descriptions in Shopify
Meta titles and descriptions do not transfer from BigCommerce automatically. You need to re-enter them manually on every product, collection, and page in Shopify.
Do not copy them blindly. Use the migration as an opportunity to review and improve your SEO metadata using the knowledge you have gained from your BigCommerce analytics.
Our guide on Shopify’s built-in SEO features explains every SEO setting available in your Shopify admin and how to configure each one correctly.
Preserve Your Internal Link Structure
BigCommerce and Shopify use different URL formats. Any internal links inside product descriptions, blog posts, or page content that point to BigCommerce URLs will become broken links after migration.
Audit all internal links in your content and update them to point to the correct Shopify URLs before launch.
Submit Your New Sitemap
After launch, immediately submit your new Shopify sitemap to Google Search Console. Shopify generates this automatically at:
yourdomain.com/sitemap.xml
Go to Search Console > Sitemaps > Add your sitemap URL and click Submit.
Also add your new domain to Search Console as a property if you changed your domain as part of the migration.
Phase 5: Configure Tax and Shipping Settings
BigCommerce tax and shipping configurations do not carry over to Shopify. You need to rebuild these from scratch in your new admin.
Our detailed Shopify tax setup guide covers US sales tax, UK VAT, EU VAT obligations, and international market configuration. Our Shopify shipping setup guide covers zones, carrier-calculated rates, and free shipping thresholds.
Configure both of these before accepting any orders on your new store.
Phase 6: Test Everything Before Switching Your Domain
Your BigCommerce store stays live until this step is complete. Test your Shopify store on a password-protected staging URL.
Pre-launch testing checklist:
| Test | What to Verify |
|---|---|
| Product data accuracy | Check 50+ random products for correct titles, prices, images, and variants |
| Navigation and menus | Click every menu item and verify it loads the correct page |
| Checkout flow | Complete a full purchase using Shopify’s test payment gateway |
| Tax calculation | Place test orders from different countries |
| Shipping rates | Verify rates display correctly at checkout |
| 301 redirects | Test 30 to 40 old BigCommerce URLs and confirm they redirect correctly |
| Mobile experience | Browse and purchase on iOS and Android |
| Email notifications | Trigger order confirmation and shipping notification emails |
| Page speed | Run PageSpeed Insights on homepage, collection, and product pages |
Never skip the mobile test. A significant portion of your organic traffic likely arrives on mobile, and a theme that works on desktop may have issues on a phone that you only discover after launch.
Phase 7: Switch Your Domain and Go Live
Once all tests pass, point your domain to Shopify.
Our step-by-step guide on Shopify domain setup walks through every DNS configuration option: connecting through Shopify’s domain manager, your existing registrar, or a third-party DNS service.
DNS propagation typically takes 24 to 48 hours to complete globally. During this window, some visitors will still see your BigCommerce store. Keep BigCommerce running and do not delete it until full propagation is confirmed.
Phase 8: Post-Migration Monitoring
The first 30 days after launch are critical. Monitor closely and respond quickly to any issues.
Daily checks for the first two weeks:
- Google Search Console for crawl errors or coverage drops
- Organic traffic levels in Google Analytics 4 versus your pre-migration baseline
- Conversion rate compared to your BigCommerce benchmark
- 404 error reports for any missed redirects
Weekly checks for the first month:
- Rank tracking for your top 30 to 50 keywords
- Core Web Vitals in Search Console
- Bounce rate and session duration on key pages
Use Shopify analytics alongside Google Analytics 4 to monitor sales performance. Any significant drop in conversion rate that did not exist on BigCommerce is usually a checkout friction issue or a theme configuration problem, not an SEO issue.
For performance baselines, apply our speed optimisation checklist in the first week to establish your new Shopify store’s performance benchmark. Also review your Shopify Core Web Vitals scores against your pre-migration BigCommerce data to confirm performance has not regressed.
If rankings drop for specific pages, check whether:
- The 301 redirect for that page is in place and returning a 301 (not a 302 or chain of redirects)
- The page’s meta title and description match what was on BigCommerce
- The page is indexed in Search Console under your new Shopify URL
- Internal links pointing to that page have been updated to the new URL
Our guide on Shopify store setup mistakes covers the post-launch errors that are most commonly traced back to incomplete migration work.

Frequently Asked Questions
Q: How long does a BigCommerce to Shopify migration take? A: A straightforward migration with under 5,000 products typically takes 3 to 6 weeks end to end, including audit, data migration, store configuration, testing, and launch. Complex stores with large catalogs, custom functionality, or ERP integrations can take 2 to 4 months.
Q: Will I lose my SEO rankings when I switch from BigCommerce to Shopify? A: You may see a temporary dip in rankings during the transition period, which is normal for any major platform change. With a complete 301 redirect map, re-entered SEO metadata, and a properly submitted sitemap, most rankings recover within 4 to 8 weeks.
Q: Does BigCommerce customer data transfer to Shopify? A: Yes, customer names, emails, and addresses transfer. Passwords do not transfer because the two platforms use different encryption methods. You need to send password reset emails to all customers after migration so they can access their accounts.
Q: Can I run BigCommerce and Shopify at the same time during migration? A: Yes, and you should. Build and test your Shopify store on a password-protected URL while your BigCommerce store continues to handle live orders. Only switch your domain to Shopify when testing is fully complete.
Q: Do BigCommerce apps work on Shopify? A: No. BigCommerce apps are built specifically for the BigCommerce platform and are not compatible with Shopify. You need to find equivalent tools in the Shopify App Store or build custom functionality using Shopify’s development framework.
Q: Is Shopify better for SEO than BigCommerce? A: Both platforms offer comparable built-in SEO capabilities including clean URLs, meta tag editing, canonical tags, and XML sitemaps. Shopify has a slight edge through its larger app ecosystem for advanced SEO tools and its faster CDN infrastructure which benefits Core Web Vitals scores.
Q: What happens to my BigCommerce store after I migrate? A: Your BigCommerce subscription continues until you cancel it. Keep BigCommerce active for at least 30 days after your Shopify launch to monitor traffic and allow time to catch any issues. Cancel once you have confirmed full traffic continuity on Shopify.
