Changing domains can feel like a pretty big SEO risk.
Your old domain has history. Google knows it. Other websites link to it. Some of your pages may have ranked for years. Then you move everything to a completely new address.
Does all of that start again from zero?
Usually, no.
Google treats a domain change as a site move, and there are ways to show clearly where your old pages have gone. You may see some movement in rankings while Google processes the change, but a well-planned migration can carry much of what your old website has built up with it.
The key is making the move easy to follow.
Your rankings belong to more than the domain name
It’s easy to think of a website’s rankings as something attached to its domain.
In reality, Google understands your website page by page. Individual URLs have content, backlinks, internal links, and their own history in search.
So when you move from:
oldbrand.com/services
to:
newbrand.com/services
Google needs to understand that these aren’t two unrelated pages. The second one is the new home of the first.
If you simply launch newbrand.com and switch off the old domain, that connection is missing. Old search results and backlinks can lead to 404s, while Google has to discover and evaluate the new URLs separately.
That’s exactly what you want to avoid.
Redirect old pages to their new versions
The most important part of a domain migration is usually the redirect map.
Each important URL on the old domain should point to its closest equivalent on the new one.
For example:
oldbrand.com/about → newbrand.com/companyoldbrand.com/pricing → newbrand.com/plansoldbrand.com/contact → newbrand.com/contact
For a permanent domain change, you’ll typically use 301 redirects.
This gives visitors a seamless route from old links to the new website and tells search engines that the move is permanent.
One thing you probably don’t want to do is send every old URL to the new homepage. It’s quicker, but it removes the relationship between individual old and new pages.
If someone follows a backlink to your old pricing page, the best destination is usually your new pricing page, not a homepage where they have to start looking all over again.
Expect some movement while Google catches up
Even with everything set up correctly, your rankings may not look exactly the same the day after the move.
That’s normal.
Google needs time to crawl the old URLs, follow the redirects, discover the new URLs, and update what it has stored in its index. During that process, rankings and traffic can fluctuate.
A temporary drop doesn’t automatically mean the migration failed.
What matters more is whether Google can consistently see the same story: the old URLs permanently moved, the new URLs contain the expected content, and the website itself now treats those new URLs as the canonical locations.
The cleaner those signals are, the easier the move is to understand.
Give Google as few mixed signals as possible
Redirects do most of the heavy lifting, but they shouldn’t be the only thing you update.
Once the new domain is live:
Redirect important old URLs to their new equivalents.
Update internal links so they use the new domain directly.
Update canonical URLs to the new addresses.
Submit a sitemap containing the new URLs.
Make sure the new pages can be crawled and indexed.
Add and verify the new domain in Google Search Console.
Use Google’s Change of Address tool when your migration is eligible for it.
Test important old URLs and monitor the migration after launch.
It’s also worth updating important external links where you can, especially profiles, directories, partner websites, or other places you control.
You won’t be able to update every backlink on the internet. That’s fine. That’s one of the reasons the redirects are there.
Try not to change everything at once
A new domain often arrives with a rebrand. And a rebrand often arrives with a new website.
Before long, you’re changing the domain, URL structure, design, navigation and half the content at the same time.
Sometimes that’s unavoidable. But from an SEO perspective, fewer simultaneous changes make the migration easier to manage and troubleshoot.
If a page ranked well before the move, keeping its content and purpose reasonably consistent while changing its address gives search engines a much clearer connection between the old and new version.
Then, once the migration has settled, you can make further changes with a better idea of what caused what.
Don’t let go of the old domain too quickly
Once the new domain is working, the old one can start to feel useless.
It isn’t.
Old backlinks, bookmarks and search results may continue sending people there long after the migration. Your redirects only work while you still control the domain and keep it pointed toward infrastructure capable of handling them.
Google recommends keeping redirects in place for at least a year after a site move. In practice, keeping the old domain and useful redirects for longer often makes sense.
There may be links to that domain that you don’t even know exist. If they’re still sending people your way, there’s little reason to turn them into dead ends.
A new domain doesn’t mean starting over
Changing domains is a significant change, and it deserves more planning than simply pointing the new domain at your website and hoping Google figures out the rest.
But it doesn’t mean throwing away years of SEO work either.
Map your important URLs. Redirect them to relevant destinations. Update the signals on your new website. Keep control of the old domain. Then give search engines some time to process the move.
Redirect Supply can handle the redirect layer separately from either website, so the old domain can keep sending visitors to the right places without keeping the old site or hosting online.
Your domain may be new.
Your website’s reputation doesn’t have to be.
