Website Redesign and Migration: An SEO-Safe Checklist

Inventory before changing URLs

Export the existing URLs, page titles, organic landing pages, backlinks and important conversions. Decide which pages should remain, be consolidated or be retired. Map each changed URL to the closest relevant replacement rather than redirecting every old page to the homepage.

Preserve content that still serves a clear audience need and improve it where the new design creates a genuine opportunity.

Test the new site before launch

Check redirects, canonical tags, robots rules, sitemap URLs, internal links, metadata and mobile rendering in a staging environment. Make sure staging is not indexable and production does not accidentally inherit a noindex directive.

• Use one consistent host and slash convention.
• Check important pages return the intended status.
• Avoid redirect chains and loops.
• Verify forms, analytics and conversion events.

Monitor after launch

Watch crawl errors, indexing, organic landing pages and conversions after release. Fix broken internal links and redirect gaps promptly. Keep the old URL map and deployment notes so future changes remain traceable.
