What Is SEO Migration?

SEO migration covers any significant change to a website that could impact search engine visibility: domain changes, HTTPS moves, CMS platform switches, URL restructuring, or major redesigns. The goal is to execute the change while preserving (or improving) organic rankings and traffic.

When You Need a Migration Plan

• Moving from HTTP to HTTPS
• Changing domains (rebrand)
• Switching CMS (WordPress → headless, Shopify → custom)
• Restructuring URL hierarchy
• Merging multiple websites
• Major redesign with URL changes

Critical Steps

1. Full crawl of current site — document every URL, its rankings, backlinks, and traffic
2. Redirect mapping — 1:1 mapping from old URLs to new URLs (301 redirects)
3. Preserve on-page SEO — titles, meta descriptions, headings, internal links
4. Update sitemap and robots.txt immediately
5. Monitor in Search Console — submit new sitemap, track index coverage
6. Watch for 404s — fix any missed redirects within 48 hours

Common Pitfalls

• Launching without redirect mapping (catastrophic traffic loss)
• Changing URL structure AND content simultaneously (impossible to diagnose issues)
• Forgetting to update internal links (redirect chains waste crawl budget)
• Not monitoring for 4-6 weeks post-launch
