Domain Migration: Moving Your Site to a New Domain

What It Is

A domain migration moves your entire site from one domain to another, such as from oldbrand.com to newbrand.com.

It is one of the highest-risk SEO changes because every URL, link, and signal is tied to the old domain.

The goal is to preserve rankings and traffic by mapping the old site to the new one perfectly.

Why It Matters

• Every existing backlink points at the old domain.
• Search engines need time to discover and trust the new one.
• A partial migration leaks rankings and traffic.
• Brand and user bookmarks depend on old addresses.
• Done well, a migration can refresh and consolidate a site.

How to Prepare

• Crawl the old site and export the full URL list.
• Create a one-to-one mapping of old to new URLs.
• Redirect the entire old domain to the new one.
• Update all internal links, canonicals, and sitemaps.
• Verify both domains in Google Search Console.

After the Migration

• Monitor redirects for errors and chains.
• Track rankings, indexed pages, and traffic week by week.
• Keep the old domain live while signals transfer.
• Update external profiles, ads, and integrations.
• Expect a temporary dip before things recover.

Common Mistakes

• Redirecting the homepage but not inner pages.
• Moving content but leaving the old domain live without redirects.
• Changing URL structure at the same time.
• Forgetting analytics and tag configuration.
• Ignoring the old domain before signals finish transferring.
