Website redesign SEO migration checklist

Protect the baseline

A redesign should improve the site without erasing search value already earned.

The first SEO migration task happens before new URLs go live.

Save the baseline.

Export current URLs.

Review organic landing pages.

Review pages earning clicks and impressions.

Review important backlinks where data is available.

Record current titles and descriptions for valuable pages.

Identify pages sales or campaigns depend on.

Save the current sitemap.

This inventory shows what needs protection.

Do not assume an old page has no value because the layout looks dated.

A plain service page might still earn qualified search traffic.

A resource might earn links.

A case study might support sales.

The redesign should keep the useful role even when presentation changes.

Prepare the migration

Start with URL decisions.

Keep an existing URL when the topic and page job remain the same.

Change a URL only when a real structural reason exists.

When a URL changes, map the old URL to the most relevant new destination.

Google recommends permanent server side redirects such as 301 or 308 for permanent moves.

Do not redirect every removed page to the homepage.

A redirect should preserve topic relevance.

Update internal links so the new site points directly to the new URLs rather than relying on redirect hops.

Review canonical tags.

Each indexable page should send a clear preferred URL signal.

Keep protocol and hostname consistent.

Review robots rules and noindex directives.

Staging protections must not follow the site into production.

Review metadata and headings.

Preserve strong search intent where the business still needs the traffic.

Review structured data.

Markup should match the visible page after redesign.

Review images and alt text.

Review forms and tracking.

A migration which protects rankings but breaks lead capture still fails the business.

Generate the new sitemap with final preferred URLs.

Monitor after launch

Launch is the start of monitoring.

Check important URLs through Search Console.

Confirm old URLs redirect correctly.

Confirm new pages return 200 status.

Confirm canonical selections.

Submit the updated sitemap.

Watch indexing.

Watch clicks and impressions.

Watch important queries.

Watch unexpected 404s.

Watch analytics and form events.

Compare changes against the saved baseline.

Search performance often moves during a migration.

Do not respond to one day of volatility with random page changes.

Look for patterns.

A priority page losing impressions needs investigation.

A large group of old URLs returning errors needs investigation.

A wrong canonical needs correction.

An isolated daily ranking movement needs more context.

Redesign migration work sits between design, development, SEO, and analytics.

Give one person clear ownership of the checklist.

Search protection works best when migration planning begins before the new site is finished.
