BigCommerce migrations can silently break SEO

BigCommerce stores often have complex URL structures, layered categories, and legacy redirects. During migration, it’s easy to accidentally redirect high-value pages to the wrong destination — or lose them entirely.

Category URLs not matching Shopify collections
Brand pages not mapped
Product URL slugs changing
Faceted navigation generating duplicate URLs
Old BigCommerce URLs still indexed by Google

What Cutover checks during a BigCommerce migration

404 and missing pages
Redirect destination accuracy
Redirect chain hop count
TTFB and total load regression
Core Web Vitals (LCP, CLS, TBT)
Page size and asset weight changes
Screenshot QA (visual diffs)
Sitemap vs crawl discovery gaps

Recommended scan settings for BigCommerce → Shopify

Discovery Method:Sitemap only (if available)
Fallback:Crawl only if sitemap is incomplete
Strip Query Params:ON (BigCommerce faceted filters create variants)
Deny Patterns:/cart, /checkout, /account, /login, /search
Max Crawl Depth:3–4

BigCommerce sites often expose large numbers of filter URLs. Stripping query parameters prevents scanning thousands of duplicates.

Why screenshot QA matters for BigCommerce migrations

Many BigCommerce stores have custom templates, PDP layouts, and category banners. Every scan captures full-page screenshots so you can confirm the Shopify theme matches the old site before launch.

  • Visual comparison of product detail pages
  • Category and collection layout validation
  • Custom template and banner rendering checks
