What the Change of Address tool is

When you move your site to a brand-new domain, you want Google to figure out that the old site and the new site are the same site, and to start showing the new URLs in search instead of the old ones. The Change of Address tool is the setting in Google Search ConsoleA free Google service that reports how a site performs in Google Search and surfaces problems with how Google crawls, indexes, and serves it. It's first-party data straight from Google — but you don't need it to appear in results. that tells Google exactly that: I moved from here to here.

Google’s own description is simple — use it “when you move your website from one domain or subdomain to another.”

What it does NOT do

This is where most of the confusion lives, so let’s get it out of the way first:

• It’s not for moving URLs inside the same domain. If you’re just reorganizing folders (say /old-folder/ to /new-folder/) on the same domain, this tool isn’t for that.
• It’s not for HTTP-to-HTTPSHTTPS is the encrypted version of HTTP — it uses TLS to authenticate the server and protect data in transit between a browser and a website. Google announced it as a lightweight ranking signal in 2014 and today conditionally prefers HTTPS pages as canonical; Chrome marks plain HTTP pages 'Not Secure.'. Google says you don’t need the Change of Address tool for that kind of move.
• It’s not for switching www to non-www (or back) on the same domain. That’s a same-domain change too, not a domain move.
• It doesn’t replace your redirects. The 301 redirectsA 301 redirect is the HTTP status code for a permanent move: it tells browsers and search engines a URL has moved for good, and it's the strongest signal for consolidating a page's ranking signals onto the new URL. Google says permanent redirects don't cause a loss in PageRank. from your old pages to your new pages are the real migration work. This tool is a helper, not the main event.

What you need before you use it

Three things have to be true or the tool won’t let you proceed:

1. You own both sites in Search ConsoleGoogle's free tool for monitoring crawling, indexing, and search performance.. You must be an owner of both the old and the new property.
2. Your redirects are already in place. Specifically, a 301 redirectA 301 redirect is the HTTP status code for a permanent move: it tells browsers and search engines a URL has moved for good, and it's the strongest signal for consolidating a page's ranking signals onto the new URL. Google says permanent redirects don't cause a loss in PageRank. from your old homepage to your new homepage (and ideally page-by-page redirects too).
3. Your properties are scoped to the whole domain — no path in the URL. This trips up more people than anything else, and it’s not quite what most guides say it is — see the Advanced tab for the actual rule.

What happens after you submit

For 180 days, Google leans toward your new site: it emphasizes crawlingCrawling is how search engines use automated bots (like Googlebot and Bingbot) to discover URLs and download pages. A page has to be crawlable to be indexed, but crawling on its own isn't a ranking factor. and indexingStoring a crawled page in the search index so it can appear in results. Crawled is not the same as indexed — Google selects what to keep, and indexing isn't guaranteed. the new domain, carries signals over from the old site, and starts preferring the new URLs in search. That’s a window, not a permanent switch — which is why you keep your redirects in place far longer than 180 days.

The 301s do the real work; the tool reinforces the signal.

It’s one input to a site migrationA site migration is any significant change to a website's URL structure, domain, platform, protocol, or hosting that can affect how search engines crawl, index, and rank it. The risk scales with how much you change at once., not a substitute for one.

What the tool actually does

Strip away the marketing and the Change of Address tool is a notification. Google spells out the mechanics: when you submit it, “it tells Google to emphasize crawlingCrawling is how search engines use automated bots (like Googlebot and Bingbot) to discover URLs and download pages. A page has to be crawlable to be indexed, but crawling on its own isn't a ranking factor. and indexingStoring a crawled page in the search index so it can appear in results. Crawled is not the same as indexed — Google selects what to keep, and indexing isn't guaranteed. your new site over crawling your old site. It also forwards various signals from the old site to the new site, and tells Google to prefer the new site over the old when determining canonical pages.”

Three jobs, then: crawl the new place first, carry the old place’s signals across, and treat the new URLs as canonical. That’s it — Google doesn’t describe this as “transferring rankings,” and I’m not going to promise you a timeline either. It reinforces a move you’ve already built with proper redirects; the redirects are what does the actual moving.

The 301s do the work; the tool is a signal

This is the heart of it. John Mueller has said the change of address tool is “just one extra signal that we use with regards to migrations” and that “it’s not a requirement.” He’s also said that if you can’t get the tool to work, with the redirects set up properly “you should be set.” (Those came via a secondary write-up of a 2021 Google Q&A, so I’m paraphrasing the gist rather than treating them as gospel — but it matches everything Google’s own docs say.)

And the docs are emphatic that redirects are the real machinery. Google says to “keep the redirects for as long as possible, generally at least 1 year,” because that window “allows Google to transfer all signals to the new URLs, including recrawling and reassigning links.” They also reassure you that “301 and other permanent redirectsA 301 redirect is the HTTP status code for a permanent move: it tells browsers and search engines a URL has moved for good, and it's the strongest signal for consolidating a page's ranking signals onto the new URL. Google says permanent redirects don't cause a loss in PageRank. don’t cause a loss in PageRankPageRank is Google's original recursive link-graph algorithm: a page's score depends on the scores of the pages linking to it, and in the published model each page's score is split across its outbound links (the simplified version: links are weighted votes). Google says it's evolved since launch but still part of its core ranking systems..” Read that next to the 180-day tool window and the priority is obvious: the redirects outlast the tool, and the redirects do the heavy lifting.

I run real migrations, and this is exactly how I treat it in practice — the Change of Address tool is one line on a much longer checklist, not the migration itself. A site migrationA site migration is any significant change to a website's URL structure, domain, platform, protocol, or hosting that can affect how search engines crawl, index, and rank it. The risk scales with how much you change at once. is the project; this tool is one accelerant inside it.

Prerequisites — get these right or it fails

The tool runs a pre-submission check (ownership plus a look for redirects on a few sample pages) before it sends anything. To pass:

• Own both properties. “You must be an owner of both the old and new properties in Search ConsoleA free Google service that reports how a site performs in Google Search and surfaces problems with how Google crawls, indexes, and serves it. It's first-party data straight from Google — but you don't need it to appear in results..” Owner, not a delegated user.
• Redirects already live. “Implement a 301 redirectA 301 redirect is the HTTP status code for a permanent move: it tells browsers and search engines a URL has moved for good, and it's the strongest signal for consolidating a page's ranking signals onto the new URL. Google says permanent redirects don't cause a loss in PageRank. from your old homepage to your new homepage.” Ideally you’ve also mapped page-level 1:1 redirects (that’s the core of any migration), but the homepage redirect is the minimum the tool looks for.
• A property scoped to the whole domain. This is the gotcha, below — and it’s not quite what most write-ups (mine included, until this update) say it is.

The domain-level gotcha — it’s not a “Domain property” requirement

This is the number-one reason a submission won’t go through, and most write-ups get the fix wrong. Google: “The Change of Address tool can be used only on properties at the domain level.” What “domain level” means here is about the shape of the URL, not a specific Search ConsoleGoogle's free tool for monitoring crawling, indexing, and search performance. verification method: no path segments. Google’s own examples of eligible properties are example.com, https://example.com, and m.example.com. A property scoped to a path — “You cannot move properties at the path level, such as http://example.com/petstore/” — can’t be the source or target.

That means you do not need Search Console’s separate, DNS-verified Domain property type to use this tool. A root-level URL-prefix property (verified by HTML file, meta tag, or Google Analytics/Tag Manager) qualifies too, as long as it points at the domain root and not a subfolder. If the tool won’t let you pick your property, the actual blocker is almost always that you’ve only ever verified a path-scoped URL-prefix property (something like https://example.com/blog/) — add a root-level property, either type, for both the old and new sites and run the tool against those.

Subdomains, www, and protocols

Two separate behaviors people conflate:

• Subdomains are NOT automatic. “The tool does not move any subdomains below the specified domain (including www).” So if your move involves www/non-www variants or subdomains, you submit a Change of Address for each. Google’s migration docs say it directly: when moving between domains, “make sure to submit Change of Address requests for all subdomains and the www and non-www variants of the old domain name.”
• Protocols ARE covered. Specifying the http property also moves the https one — “if you specify http://example.com, it also moves https://example.com.” So you don’t submit twice for protocol; you do submit separately for each subdomain.

TIP Verify the old-to-new redirect before submitting the move

Change of Address is an additional migration signal; the URL-level 301 mapping remains the mechanism that carries users and search engines to the new host.

The 180-day window — and what happens after

“These actions continue for 180 days after you start migration in Search Console.” For that window Google emphasizes the new site, forwards signals, and prefers the new canonicals. The request is also cancelable within that window.

After 180 days the forwarding relationship lapses. If your old site is still live and crawlable at that point, Google can treat it as unrelated again — which is exactly why your redirects must outlive the tool. Keep them live for at least those 180 days, and longer than that for as long as the old URLs are still pulling any Google Search traffic.

That’s a different piece of advice from what Google says about the domain name itself, and it’s worth not confusing the two: separately, Google recommends keeping the registration of your old domain active for at least a year after the move, so nobody else can register the abandoned name and reuse whatever trust or links it built up (think spam or phishing riding on your old domain’s history). One is about how long you redirect; the other is about not letting the domain name lapse. They’re not the same clock.

When NOT to use it

• Moving URLs within the same domain — folder restructures on the same host. Not this tool.
• HTTP-to-HTTPSHTTPS is the encrypted version of HTTP — it uses TLS to authenticate the server and protect data in transit between a browser and a website. Google announced it as a lightweight ranking signal in 2014 and today conditionally prefers HTTPS pages as canonical; Chrome marks plain HTTP pages 'Not Secure.' — Google explicitly says you don’t need it.
• Switching www to non-www (or back) on the same domain — same-domain variant swaps aren’t a domain move either; handle those with redirects and a canonical, not Change of Address.
• IP / server / CDN moves with no URL change — if your URLs don’t change, the tool doesn’t apply.
• Merging or splitting sites — the Change of Address tool is a 1:1 site move. Merging two domains into one, or splitting one into many, is not a “move” and not what the tool is for.

One documented exception worth knowing: your whole old domain can move into a path on a different destination domain (say oldbrand.com folding into newbrand.com/oldbrand/). The source still has to be domain-level, but the destination is allowed to have a path.

Don’t forget Bing

Bing Webmaster ToolsMicrosoft's free portal for monitoring and improving how a site appears in Bing search — the peer to Google Search Console, plus IndexNow instant indexing, richer backlink data, and keyword volumes. Because Bing's index also feeds Microsoft Copilot, it doubles as a window into AI-search visibility. has its own equivalent, the Site Move tool, which serves the same purpose for Bing. Notably, Bing’s version supports both whole-site (domain) moves and directory/path-level moves, where Google’s is domain-level only. If you submit the move in Google, submit it in Bing too.

Where this fits

The Change of Address tool is one step in a site migrationA site migration is any significant change to a website's URL structure, domain, platform, protocol, or hosting that can affect how search engines crawl, index, and rank it. The risk scales with how much you change at once., not the whole thing. The 301 redirects, the 1:1 URL mapping, the pre-migration crawl baseline, and the post-launch monitoring are where a migration is won or lost. This tool just makes sure Google hears about the move clearly and quickly.

It's a supporting signal for a domain migration — the 301 redirects do the real work of transferring rankings. — it’s the same set of things the tool’s pre-submission check looks for, plus the property-type fix that trips most people up:

• You’ve planned to keep redirects live for at least 180 days, longer while old URLs still get any Google Search traffic — and, separately, to keep the old domain’s registration active for at least a year.

• You’ll also submit the move in Bing Webmaster ToolsMicrosoft's free portal for monitoring and improving how a site appears in Bing search — the peer to Google Search Console, plus IndexNow instant indexing, richer backlink data, and keyword volumes.

The mental models

1. The tool is a signal; the redirectsA redirect sends browsers and crawlers from a requested URL to a different one. An HTTP redirect specifically is a 3xx status code paired with a Location header; meta refresh and JavaScript redirects achieve a similar navigation without being a 3xx response themselves. Permanent redirects (301/308) are Google's signal the target should be canonical; temporary ones (302/303/307) aren't. are the machinery. A migration succeeds or fails on 301s and 1:1 URL mapping. The Change of Address tool only emphasizes crawlingCrawling is how search engines use automated bots (like Googlebot and Bingbot) to discover URLs and download pages. A page has to be crawlable to be indexed, but crawling on its own isn't a ranking factor. the new site, forwards signals, and sets new canonicals. Build the redirects first; the tool just announces the move.

2. The “is this even the right tool?” test. Ask what changed:

• New domain or subdomain? → Change of Address toolA setting in Google Search Console that tells Google you've moved your whole site to a new domain or subdomain. It's a supporting signal for a domain migration — the 301 redirects do the real work of transferring rankings. applies.
• Same domain, different URLs/folders? → not this tool.
• HTTP → HTTPSHTTPS is the encrypted version of HTTP — it uses TLS to authenticate the server and protect data in transit between a browser and a website. Google announced it as a lightweight ranking signal in 2014 and today conditionally prefers HTTPS pages as canonical; Chrome marks plain HTTP pages 'Not Secure.'? → you don’t need it.
• Same domain, www ↔ non-www? → not this tool.
• IP / server / CDN, URLs unchanged? → doesn’t apply.
• Merging or splitting sites? → not a 1:1 move; not this tool.

3. Two clocks, plus a third one people forget. The tool’s forwarding lasts 180 days — keep redirects live at least that long, longer while old URLs still get traffic. Separately, keep the old domain’s registration active for about a year so nobody grabs it and reuses its trust. Different clocks, different reasons: one’s about signal transfer, the other’s about not losing the domain name.

4. Domain-level, not “Domain property.” If the tool won’t accept your property, it’s almost always because you verified a path-scoped URL-prefix property. The fix is any property scoped to the whole domain — a DNS-verified Domain property or a root-level URL-prefix property both work.

Change of Address — cheat sheet

Use it / don’t use it

Fast facts

• Duration: Google emphasizes the new site, forwards signals, and prefers new canonicals for 180 days; the request is cancelable within that window.
• Property scope: no path in the URL. A Domain property AND a root-level URL-prefix property both qualify — path-scoped properties are the #1 rejection reason.
• Subdomains: not automatic (including www) — submit one each.
• Protocols: covered — specifying http:// also moves https://.
• RedirectsA redirect sends browsers and crawlers from a requested URL to a different one. An HTTP redirect specifically is a 3xx status code paired with a Location header; meta refresh and JavaScript redirects achieve a similar navigation without being a 3xx response themselves. Permanent redirects (301/308) are Google's signal the target should be canonical; temporary ones (302/303/307) aren't.: keep them live ≥ 180 days, longer while old URLs still get traffic (301s don’t lose PageRankPageRank is Google's original recursive link-graph algorithm: a page's score depends on the scores of the pages linking to it, and in the published model each page's score is split across its outbound links (the simplified version: links are weighted votes).

Change of Address mistakes that derail migrations

Submitting before redirectsA redirect sends browsers and crawlers from a requested URL to a different one. An HTTP redirect specifically is a 3xx status code paired with a Location header; meta refresh and JavaScript redirects achieve a similar navigation without being a 3xx response themselves. Permanent redirects (301/308) are Google's signal the target should be canonical; temporary ones (302/303/307) aren't. are ready. The request announces a move; it does not create one. Deploy and test one-to-one permanent redirectsA 301 redirect is the HTTP status code for a permanent move: it tells browsers and search engines a URL has moved for good, and it's the strongest signal for consolidating a page's ranking signals onto the new URL. Google says permanent redirects don't cause a loss in PageRank. first.

Redirecting every old URL to the new homepage. That destroys page-level equivalence and gives users and crawlersA crawler — also called a spider or bot — is an automated program that fetches web pages, extracts their links, and queues new URLs to visit. Search engines use crawlers to discover and download content for their index. the wrong destination. Map each valuable old URL to its closest new counterpart; retire unmatched content deliberately.

Using a path-scoped property. The tool requires a property scoped to the whole domain — no path in the URL. A root-level URL-prefix property works fine; you don’t need a DNS-verified Domain property specifically. Verify a domain-level property (either type) instead of repeatedly retrying an ineligible path-scoped source or destination.

Submitting only the apex and assuming www or other subdomains follow. They do not. Inventory host variants and submit a separate request for each relevant move.

Removing redirects after 180 days. That confuses the tool’s active window with your redirect timeline. Keep permanent redirects live at least 180 days, longer while old URLs still receive visits or links.

Letting the old domain’s registration lapse. Google recommends keeping it active for at least a year after the move so nobody else can register the abandoned domain and reuse whatever trust or links it built up.

Using the tool for a same-domain restructure or HTTPSHTTPS is the encrypted version of HTTP — it uses TLS to authenticate the server and protect data in transit between a browser and a website. Google announced it as a lightweight ranking signal in 2014 and today conditionally prefers HTTPS pages as canonical; Chrome marks plain HTTP pages 'Not Secure.' change. Those migrations have different signals and do not need Change of Address. Applying the wrong tool does not make a weak redirect plan stronger.

Change of Address troubleshooting

The old or new property isn’t available in the selector

Likely cause: it’s scoped to a path (a URL-prefix property pointed at a subfolder), or your account is not an owner. Fix: verify a property scoped to the whole domain — a DNS-verified Domain property or a root-level URL-prefix property both work — for both sites, then confirm owner access before reopening the tool.

The pre-submission check says redirects are missing

Likely cause: the old homepage does not return a direct permanent redirectA 301 redirect is the HTTP status code for a permanent move: it tells browsers and search engines a URL has moved for good, and it's the strongest signal for consolidating a page's ranking signals onto the new URL. Google says permanent redirects don't cause a loss in PageRank. to the new homepage, the redirectA redirect sends browsers and crawlers from a requested URL to a different one.

Permanent redirects (301/308) are Google's signal the target should be canonical; temporary ones (302/303/307) aren't. is conditional, or an intermediate hop fails. Fix: test the old homepage as an unauthenticated request, follow the chain, and make it one permanent hop to a successful new homepage. Then sample page-level mappings too.

The request succeeded, but old URLs still appear in search

Likely cause: Google has not recrawled everything yet, redirects are inconsistent, or the new pages canonicalize back to the old domain. Fix: inspect representative old and new pairs, verify the redirect and self-canonical, submit the new sitemapA sitemap is a file that lists the pages, images, videos, and other files on your site so search engines can discover them. It helps discovery, but submitting a sitemap doesn't guarantee crawling or indexing., and watch crawlingCrawling is how search engines use automated bots (like Googlebot and Bingbot) to discover URLs and download pages.

Crawled is not the same as indexed — Google selects what to keep, and indexing isn't guaranteed. over time. A request is not an instant SERP replacement.

Some subdomains did not move

Likely cause: only the parent domain’s request was submitted. Fix: verify each affected source and destination subdomain and submit its own request, including the relevant www variant.

Traffic fell after the move

Likely cause: the problem is usually in migration execution—missing URL mappings, redirect chainsA → B → C instead of A → C. Each hop loses link equity and adds latency., blocked resources, wrong canonicals, internal linksAn internal link is a hyperlink from one page on a website to another page on the same website. Internal links help search engines discover your pages and pass ranking signals (PageRank and anchor-text context) between them. still pointing old, or missing content—not the notification itself. Fix: compare the pre-launch URL inventory with live redirects, status codes, canonicals, indexability, sitemapsA sitemap is a file that lists the pages, images, videos, and other files on your site so search engines can discover them. It helps discovery, but submitting a sitemap doesn't guarantee crawling or indexing., and logs before canceling or resubmitting the request.

Prove the domain move is working

Run these tests after launch and keep a dated sample so regressions are visible:

A passing Change of Address screen proves the notification was accepted. These tests prove the migration machinery around it actually works.
