Will a Domain Change Hurt Your SEO? Rankings, Backlinks and Recovery Explained

A client rebrands, buys a new domain and wants it live by Monday. The website itself barely changes, but every URL does. That is the moment search visibility is most at risk, and it is usually the agency that gets the call when organic enquiries dip a fortnight later.

A domain change does affect SEO. The good news is that the effect is normally temporary, because Google can move almost all of a site’s ranking signals to the new address. The bad news is that it only does so when the old and new URLs are connected properly. Here is what happens behind the scenes, what a healthy move looks like, and how to find the problem when traffic keeps falling.

What changes for Google when a site moves to a new domain?

To Google, a new domain is a new set of addresses. Even if every page looks identical, it has to find the new URLs, follow the redirects from the old ones and decide that the new page replaces the old one in its index. Until that work is done, old and new URLs can both appear in results and positions move around.

The same applies whatever the reason for the move: a rebrand, a switch from .co.uk to .com, a .org to .com change, or two sites merging into one. In the first weeks you will typically see:

• Positions for key terms going up and down from day to day.
• A mix of old and new URLs in search results.
• Indexed pages falling in the old Search Console property and rising in the new one.
• Backlink and authority figures in SEO tools that look worse than before.

None of that means the site has lost its history. History is only lost when the old URLs lead nowhere.

What does a healthy domain move look like?

Every site moves at its own pace, so treat the stages below as a pattern rather than a timetable. What matters is the direction of travel.

Stage	Healthy sign	Red flag
Launch day	Old URLs return a 301 to the matching new page, and new pages return a 200	Old URLs return 404 errors, or all of them redirect to the homepage
Weeks one to four	Rankings and clicks fluctuate; old and new URLs both show in Google	New URLs are not being indexed at all
Once settled	The new domain carries most indexed pages and most clicks	Clicks to key pages are still falling with no sign of a floor

If a red flag appears, start investigating straight away. Waiting for Google to catch up rarely fixes a broken redirect.

What happens to backlinks after a domain change?

Nothing happens to the links themselves. They sit on other people’s websites and keep pointing at the old address. What changes is where that address leads. With a permanent 301 redirect in place, a visitor or crawler following the link lands on the new page, and Google passes the link’s value along with it.

Here is the path a link from an industry site takes before and after the move:

# Before the move
industrysite.co.uk -> oldbrand.co.uk/guide/

# After the move, via a 301 redirect
industrysite.co.uk -> oldbrand.co.uk/guide/ -> newbrand.co.uk/guide/

# Ideal, once the publisher edits the link
industrysite.co.uk -> newbrand.co.uk/guide/

Do redirects pass link value?

In most cases, yes. Google’s Gary Illyes said in 2016 that 30x redirects no longer lose PageRank, and Google treats a permanent redirect as a strong signal that the new URL should take the old one’s place. The value transfers best when each old page points at its true equivalent. A deep article redirected to the homepage passes far less.

Which links are worth asking to update?

Do not chase hundreds of webmasters. Focus on the handful that matter:

• Links that send real referral visits.
• Links from trade bodies, industry publications and partners.
• Links pointing at revenue pages such as services or products.
• Everything the client controls: Google Business Profile (vital for local SEO), social profiles, directory listings and email signatures.

Why does the new domain show such a low authority score?

Domain Authority (Moz), Domain Rating (Ahrefs) and Authority Score (Semrush) are calculated by each tool from its own crawl of the web. Google does not use any of them. A new domain usually scores low at first simply because the tool has not yet followed the redirects from the old one.

Judge the move on what Google reports instead: indexed pages, clicks and impressions in Search Console, and enquiries or sales in GA4. Third-party scores lag behind reality, so treat them as a trend line, not a verdict.

Which redirects should you use for a domain change?

Use permanent, server-side redirects: a 301, or a 308, which Google treats the same way. They tell Google the move is permanent so the new URL replaces the old one. Temporary redirects (302 and 307) ask Google to keep showing the old URL, which is the opposite of what you want.

Redirect	What it tells Google	Right for a domain move?
301, server-side	Moved permanently; index the new URL	Yes, the default choice
308, server-side	Moved permanently; treated like a 301	Yes
302 or 307	Moved for now; keep the old URL	No
Instant meta refresh	Read as permanent	Only if server redirects are impossible
JavaScript redirect	Seen only if the page renders	Last resort

Google’s guide to redirects and Google Search confirms that a permanent server-side redirect is the most reliable option. Avoid chains as well. Each old URL should reach its final address in one hop, not via a www version and then a non-www version.

What if the site moved without any redirects?

Then Google sees an unrelated new website. Old URLs return errors, backlinks lead to dead pages, and the new site starts from nothing. For an established business that can mean a sharp, lasting fall in organic enquiries.

Recovery is not guaranteed, but the sooner you act, the more you usually get back:

1. Rebuild the list of old URLs from the old Search Console property, an old XML sitemap, a backlink tool’s top pages report or the Wayback Machine.
2. Put the old domain back online with DNS pointing at a server and a valid SSL certificate, so https links can redirect without a browser warning.
3. Add page-to-page 301 redirects from every old URL to its matching new page. Redirecting everything to the homepage can be treated as a soft 404.
4. Test a sample with a crawler or curl, looking for one 301 followed by a 200.
5. File a Change of Address in Search Console if both properties are verified and it was a whole-domain move.
6. Submit the new sitemap and review both properties every week.

How do you diagnose a traffic drop after a domain change?

A short dip is expected. A drop that keeps going usually traces back to one of a few technical causes. Compare the same pages and the same queries before and after the move; site-wide totals hide the pages doing the damage.

What you see	Likely cause	How to confirm and fix
Old URLs return 404	Missing redirects	Crawl the old URL list and add page-to-page 301s
Homepage fine, deep pages gone	Mass redirects to the homepage	Map each old page to its real equivalent
Search Console says Google chose a different canonical	Canonicals still point at the old domain	Check URL Inspection and set self-referencing canonicals
New pages “Excluded by noindex tag”	Staging settings left switched on	Remove noindex; check robots.txt and X-Robots-Tag headers
GA4 near zero, Search Console clicks normal	Tracking missing on the new domain	Check the GA4 tag, data stream URL and Tag Manager triggers
Slow pages, long redirect chains	Internal links still use the old domain	Update menus, footers and in-content links
Competitors fell at the same time	Seasonality or an algorithm update	Compare like-for-like periods and the wider market

How long does recovery take?

There is no fixed figure. Google’s site move documentation says a small to medium-sized site can take a few weeks for most pages to move, and larger sites take longer. Crawl frequency, server speed and the number of URLs all play a part.

Hold back on other big changes, such as a redesign or a new URL structure, until the move has settled. If both have to happen, our website migration team can sequence them. Google itself recommends making site changes one after another rather than together.

How do you check that rankings and links are coming across?

Use several sources, not one score. Together they show whether Google is moving the signals or something is in the way.

1. Search Console, both properties: clicks, impressions and queries should shift from old to new. “Page with redirect” in the old property’s indexing report is expected.
2. URL Inspection: the Google-selected canonical for key pages should be the new URL.
3. GA4: compare organic sessions and conversions with the pre-move baseline, once tracking is confirmed.
4. Backlink tool: export the most-linked old URLs and check each one redirects to the right page.
5. Crawler: run the old URL list through Screaming Frog in list mode to catch 404s, loops and chains.

For a quick spot check on a single URL from the command line:

curl -sIL https://oldbrand.co.uk/services/ | grep -iE "^HTTP|^location"

Planning a move rather than repairing one? Our step-by-step plan for switching from .org to .com covers the redirect rules, testing and Search Console steps, and it works for any domain change. Google’s Change of Address tool only applies to whole-domain moves where you own both properties.

Should the client keep the old domain?

Yes, and for longer than most people expect. Google’s site move guidance says to keep redirects in place for as long as possible, generally at least a year. For an established business, keeping them permanently is the safer call, because old links live on in articles, directories and PDFs for years.

Never let the old domain lapse. Someone else can register it, inherit the backlinks and use the name to impersonate the business.

Frequently asked questions

Will a domain change lose my backlinks?

No, provided the old URLs redirect. The links stay where they are and the 301 redirects carry visitors and search engines to the new pages. For the most valuable links, ask the publisher to update the URL so it points straight at the new domain.

Do 301 redirects pass full SEO value?

Usually, yes. Google’s Gary Illyes said in 2016 that 30x redirects no longer lose PageRank. It works best for one-to-one redirects between equivalent pages, and identical rankings are still not guaranteed.

Does a new domain start from zero?

Not in Google’s eyes, if the old URLs redirect properly. Third-party scores may start low until the tools catch up, so track progress in Search Console rather than in DA or DR.

Can we change the domain and redesign at the same time?

You can, but if rankings drop you will not know which change caused it. Move the domain first, let it settle, then launch the redesign.

How long should the redirects stay live?

At least a year, according to Google, and ideally for good. Keep the old domain registered too, so nobody else can pick it up.

The bottom line

A domain change shakes rankings for a while, but a well-connected move carries the site’s links and history to the new address. Map every URL, redirect page to page, judge progress in Search Console rather than third-party scores, and treat any drop that keeps going as a technical fault to trace.
