A university can change its official domain, for example from olduniversity.edu to newuniversity.edu, without permanently losing its search visibility, backlinks or web impact. Whether it does depends almost entirely on how the move is carried out. The three mechanisms that matter most for Google Search are one-to-one permanent (301 or 308) redirects from every old URL to its equivalent new URL, verification of both the old and new domains in Google Search Console, and Google's Change of Address tool. Rebranding the homepage, updating Google Analytics or editing social-media profiles does not tell Google Search that a site has moved.
This guide explains what Google's current documentation says about site moves, what happens to backlinks and indexed pages, and which academic and institutional systems a university also needs to update. It is written for university IT departments, web administrators, communications teams and SEO staff. Most of the principles apply equally to research institutes, colleges and other organisations.
A domain migration is the permanent move of a website from one domain name to another, with each old URL redirected to its corresponding new URL so that users, search engines and linking websites reach the same content at its new address. Google calls this a site move with URL changes. It is a different exercise from redesigning a website, replacing a content management system or moving to a new hosting provider, although these changes are often made at the same time.
Universities change domains for many reasons: an institutional name change, a merger of two or more institutions, a move from a generic domain to a national academic domain (or the reverse), the consolidation of several legacy domains, or a rebrand. Whatever the reason, the old domain usually carries decades of accumulated signals: links from other universities, government agencies, publishers and news media; indexed pages in search engines; citations in theses, papers and policy documents; and researcher profiles across scholarly platforms.
Webometrics' own best-practice guidance for universities recommends using a single, consistent institutional domain and avoiding domain changes or multiple main domains. When a change is unavoidable, the goal is to make it complete, permanent and well documented.
Google's site-move documentation (last updated 20 August 2026) describes a domain move as a process of preparing the new site, mapping old URLs to new URLs, deploying redirects and then monitoring the transition. Four points from Google's guidance shape everything else:
A common misunderstanding is that updating Google Analytics, or Google Analytics 4 (GA4), informs Google that a website has moved. It does not. Google Analytics measures visitor behaviour on pages where its tag is installed; it is not a channel for communicating site moves to Google Search. The mechanisms Google Search relies on are permanent redirects, Search Console verification of both domains and the Change of Address tool, supported by updated canonical tags, internal links and sitemaps. Analytics configuration matters for continuity of reporting, which is covered below, but it has no role in how Google indexes the new domain.
Backlinks pointing to the old domain continue to have value after a domain change if each old URL permanently redirects to its corresponding new URL. Google's site-move guidance is explicit that 301 and other permanent redirects do not cause a loss in PageRank, the link-based signal Google has long used. It also recommends keeping redirects for at least one year so that Google can transfer signals to the new URLs, including recrawling and reassigning links on other websites that still point to the old addresses.
Three conditions determine whether that transfer works well:
For content that genuinely no longer exists, Google recommends returning a 404 or 410 status code rather than forcing a redirect to an unrelated page. For content that was merged, the closest equivalent page is usually the right target.
Redirects preserve backlinks; they do not replace them. Over time, updating the most important external links at their source (partner universities, ministries, accreditation bodies, publishers and major directories) removes a dependency on the old domain and gives users a faster, direct path.
The URL map is the foundation of the whole migration. Google recommends compiling old URLs from existing sitemaps, server logs, analytics data, Search Console's Links report and the CMS itself, including embedded resources such as images, PDFs, videos, CSS and JavaScript files. Each old URL is then mapped to its new equivalent.
At a university, this inventory must extend well beyond the main website. It should include faculty and department sites, the library, the institutional repository, open journal platforms, research centre sites, the news archive, staff profile pages, admissions portals, course catalogues and any document libraries that hold policies, theses or reports.
Google recommends HTTP permanent redirects, such as 301 and 308, and identifies server-side redirects as the most reliable method. Under the HTTP standard (RFC 9110), both 301 (Moved Permanently) and 308 (Permanent Redirect) indicate that a resource has a new permanent address; the difference is that 308 does not allow a client to change the request method (for example from POST to GET), while 301 does. For ordinary web pages either is appropriate. JavaScript redirects should be a last resort, because Google may not always render them.
Test redirects before and after launch, using Search Console's URL Inspection tool and command-line or crawler-based checks of the full URL map.
A domain migration includes every variant through which the old site can be reached: olduniversity.edu, www.olduniversity.edu, the http and https versions, and every subdomain such as library.olduniversity.edu, repository.olduniversity.edu or journals.olduniversity.edu. Each should redirect to its correct equivalent on the new domain. Subdomains are where university migrations most often fail, because they are frequently run by different teams or external vendors.
Webometrics has previously examined how policies can differ across a single institution's separate web properties, in its study of AI-crawler directive consistency across university web properties. The same fragmentation affects migrations: a subdomain no one remembered can stay on the old domain for years.
Google recommends verifying both the old and the new site in Search Console, including their variants. Search Console offers two property types: a Domain property, verified through a DNS record, covers all subdomains and protocols, while a URL-prefix property covers only URLs under one specific prefix and can be verified in several ways. For a university migration, Domain properties for both the old and the new domain give the broadest monitoring view.
If verification uses an HTML file, that file must also exist on the new site. Google also advises reviewing settings carried by the old property, for example re-uploading any disavow file to the new property.
Once redirects are live, the owner of both properties, using the same Google account, submits the move through Search Console's Change of Address tool. The tool runs validation checks, including whether the old homepage redirects to the new one. According to Google:
Every page on the new domain should carry a self-referencing rel="canonical" tag pointing to its new URL. Google's canonicalization documentation describes redirects and canonical tags as strong signals and sitemap inclusion as a weaker one, and warns against sending conflicting signals for the same page. A new page that still declares an old-domain URL as canonical works against the redirect.
Multilingual university sites should update all hreflang annotations to the new URLs. All internal links, including navigation menus, footers, breadcrumbs, embedded links in news articles and links inside PDFs that the university controls, should point directly to the new domain instead of relying on redirects.
Google recommends submitting a sitemap of the new URLs once redirects are live. Sitemaps should list only final, canonical new-domain URLs. Before launch, check the new site's robots.txt and page-level directives: staging sites are commonly protected with Disallow: / or noindex, and these settings must not be carried into production. The old domain should also remain crawlable, because search engines can only discover a redirect on a URL they are permitted to request.
Google's guidance differs slightly by document, but always points in the same direction:
| Source | Recommendation |
|---|---|
| Google site-move documentation | Keep redirects as long as possible, generally at least one year |
| Google Change of Address documentation | Keep 301 redirects for at least 180 days, longer if the old URLs still receive search traffic; continue paying for the old domain for at least a year |
| Microsoft Bing website-migration guidance (2020) | Keep redirects live for at least one to two years, preferably longer |
For universities, Webometrics recommends treating the old domain as a permanent institutional asset rather than a temporary one. Academic references have unusually long lives: theses, journal articles, books, accreditation reports, government documents and printed material can cite a university URL for decades. Keeping the old domain registered and redirecting indefinitely protects those references. An expired university domain can also be registered by a third party, who would then receive the institution's historical links and traffic.
After the move, Google suggests watching the sitemaps and indexing reports for both properties, checking for unexpected increases in "not found" errors, and tracking whether the new URLs are gaining impressions and clicks in the Performance report. Server logs should be monitored too: Google notes that it temporarily crawls more heavily after a site move, so the new servers need enough capacity.
Google recommends contacting the websites that link to the old URLs, prioritising the most important ones, and updating social-media profiles and advertising landing pages. Search Console's Links report for the old property is a practical starting list. For universities, the most valuable links usually come from partner institutions, government and accreditation bodies, research funders, publishers, library catalogues and news media.
GA4 matters for measurement, not for search engines. The Google Analytics help documentation confirms that a web data stream's name and website URL can be edited from the stream details screen, so the stream can be updated to reflect the new domain. Because GA4 collects data through the Google tag installed on each page, keeping the same tag on the new domain keeps reporting within the same property. Google's site-move documentation also notes that some teams may prefer a new analytics profile if they want clean separation in their reports, so the choice depends on reporting needs.
If old and new domains both serve live content during a transition, or if visitors move between separate institutional domains, GA4's cross-domain measurement can keep sessions joined across domains. Record the migration date in internal reporting, so that changes in traffic, referral sources and landing pages can be interpreted correctly afterwards.
Google is not the only discovery channel. Microsoft Bing Webmaster Tools includes a Site Move tool that also requires site verification and 301 redirects. Other crawlers, including those used by AI search tools, generally rely on the same redirects, links and sitemaps to find content at its new address.
A university's domain appears in hundreds of places outside its own website. Updating these is not a signal to Google Search that the site has moved; that remains the job of redirects and Search Console. These updates matter because they keep the institution's identity consistent, keep research discoverable and reduce dependence on redirects over time.
| System | What to update | Why it matters |
|---|---|---|
| Google Scholar profiles | Homepage links on researcher profiles; researchers' verified institutional email addresses where these use the old domain | Google Scholar requires a verified email address at the researcher's university for profiles to be eligible to appear in Scholar search results. Updating Scholar profiles does not inform Google Search of the move. |
| Institutional repository | Base URL, item URLs, OAI-PMH endpoint, sitemaps and repository registrations with aggregators | Google Scholar's inclusion guidelines ask for each moved article URL to 301-redirect to its new location and not to the homepage |
| DOIs (Crossref and DataCite) | Registered resolution URLs for every DOI the university or its press registered | DOI strings never change, but the URL each DOI resolves to does. Crossref supports bulk resource-URL updates after a platform migration, and DataCite allows the URL to be updated without changing other metadata |
| University journals and presses | Journal platform URLs, DOI resolution URLs, journal-directory and indexing-service records | Keeps journal articles resolvable and correctly attributed |
| Faculty and staff profile pages | Profile URLs, embedded links and email addresses | These pages are frequently linked from conferences, publishers and research networks |
| ORCID records | Researchers' website links and affiliation information that reference the old domain | ORCID records are maintained by researchers (and by connected institutional systems), so communication with staff is required. See Webometrics' study of ORCID visibility across Sudanese universities for why researcher identifiers matter |
| Research Organization Registry (ROR) | The organisation's website link in its ROR record | ROR accepts curation requests from anyone; approved changes are released in batches at least monthly |
| Publisher and research-database affiliations | Institutional website and address records held by research-information systems and databases | Supports correct affiliation matching for future publications |
| Accreditation and government directories | Ministry, quality-assurance agency and national university-register entries | These are among the most authoritative links a university holds |
| Social-media profiles | Website fields on all official accounts | Recommended directly in Google's site-move guidance |
| Wikipedia and Wikidata | The "official website" field in the Wikipedia infobox and the official website (P856) statement in Wikidata | Use only independently verifiable information. Wikipedia's conflict-of-interest guideline asks editors connected to a subject to disclose that connection and generally to propose changes rather than make them directly |
| Partner universities | Links on partnership, exchange, joint-programme and consortium pages | Often long-standing, contextually relevant academic links |
| Academic and admissions directories | Listings in international education directories, scholarship portals and national admissions systems | High-traffic routes used by prospective students |
| Institutional email references | Email signatures, contact pages, mailing lists and accounts registered with old-domain addresses | Keep the old email domain receiving mail during the transition so that password resets, verification messages and correspondence are not lost |
| Citation and profile services | Researcher-profile and academic-networking platforms, conference systems and grant portals | Reduces the number of outdated institutional links in circulation |
noindex tags and robots.txt blocks from the new site.| Mistake | What goes wrong |
|---|---|
| Shutting down the old domain | Every backlink, bookmark and citation to the old domain stops working, and no signals can be passed through redirects |
| Allowing the old domain to expire | A third party can register it and capture the institution's historical links and traffic; Google recommends paying for the old domain for at least a year |
| Redirecting everything to the homepage | Users lose the content they were looking for, and Google may treat the redirects as soft 404s |
| Using temporary redirects (302 or 307) | Google does not treat temporary redirects as a signal that the new URL should be canonical |
| Forgetting subdomains | Library, repository, journal and department subdomains stay on the old domain or break |
| Changing the domain, CMS, design and URL structure at once without planning | Problems become hard to diagnose; Google recommends making changes one after another |
| Incorrect canonical tags | New pages that point their canonical to old-domain URLs send conflicting signals |
| Blocking the new site with robots.txt or noindex | Staging restrictions carried into production can prevent the new site from being indexed |
| Not updating XML sitemaps | Sitemaps that still list old URLs or redirecting URLs send mixed signals |
| Not verifying both Search Console properties | Change of Address cannot be used, and the move cannot be monitored from both sides |
| Not using Change of Address | Google loses an explicit signal that supports the move |
| Removing redirects too quickly | Signals and links that have not yet been transferred are lost, and old references break |
| Leaving long redirect chains | Each extra hop slows users and adds risk; Google recommends short chains |
Webometrics is a UNIRANKS project dedicated to the development and application of webometric university evaluation and research; Webometrics.org is the project's dedicated public website and publication platform. The current Webometrics methodology evaluates universities through three indicators: Impact, Openness and Excellence. These are explained in more detail in What Do Impact, Openness and Excellence Mean in the Webometrics Ranking?
Two parts of the methodology are directly relevant to a domain change.
First, attribution depends on the institutional domain. The methodology states that each institution is associated with a verified primary institutional domain, that eligible digital resources must be sufficiently attributable before they contribute to institutional measurement, and that one normalised domain represents one web asset. When a university moves to a new primary domain, the association between the institution and its new domain needs to be clear and consistent.
Second, Webometrics does not rank universities by their position in Google. The methodology describes a multi-source data architecture in which different measurement categories may rely on different validated sources, and no single external provider independently determines an institution's ranking. Search-engine visibility is one of the areas the Impact indicator considers, alongside web authority, digital reach and online presence, with web signals analysed through UNIRANKS Web Growth Intelligence (GI) and research intelligence through the UNIRANKS Open Index (OI).
A domain migration does not, on its own, change how Webometrics measures a university. A poorly executed migration can, however, temporarily fragment or disrupt the web signals that any web-impact analysis observes: links may point to an old domain that no longer resolves, content may be split across two domains, subdomains may be left behind, and search engines may take longer to recognise the new site. A carefully executed migration, with one-to-one permanent redirects, consistent identity records and an old domain that remains active, keeps that historical web presence connected to the institution.
Universities that change their primary domain should make sure the new domain is consistently declared across their own website, scholarly registries and public directories, and can inform Webometrics of the change through the Webometrics contact page. For broader context on the signals that make a university website authoritative, see What Makes a University Website Authoritative? Digital Presence Signals That Matter and What Is a Web Ranking?
Some temporary fluctuation is normal. Google states that rankings may fluctuate while it recrawls and reindexes a moved site, and that a medium-sized site may take a few weeks or more before the new URLs replace the old ones in results, with larger sites taking longer. A well-executed migration aims to make this disruption temporary; no migration method can guarantee unchanged rankings.
Google treats both 301 and 308 as permanent redirects and recommends either. The difference under the HTTP standard is that 308 preserves the request method, which matters for forms or APIs that receive POST requests. For ordinary web pages, 301 is the most widely used.
Google's site-move documentation recommends keeping redirects as long as possible, generally at least one year, and its Change of Address documentation recommends at least 180 days and longer while traffic continues. Because academic references can persist for decades, universities should plan to keep the old domain registered and redirecting indefinitely.
No. Google Analytics measures visitors to pages where its tag is installed. It does not notify Google Search of a site move. Use permanent redirects, verify both domains in Search Console and submit a Change of Address.
No. Updating Google Scholar profiles keeps researcher homepages and verified institutional email addresses accurate and supports academic discoverability, but it is not a site-move signal for Google Search.
No. Google states that the Change of Address tool is not needed for http-to-https moves or for www/non-www changes on the same domain. It is used when moving to a different domain or subdomain.
They need to be migrated and redirected individually. Google's Change of Address tool does not move subdomains automatically, so each old subdomain that moves to a new domain needs its own redirects and its own Change of Address submission.
Yes. Google suggests that large sites may move a section first to test the effect on traffic and indexing, while noting that a partial move is not necessarily representative of a whole-site move.
The Webometrics methodology associates each institution with a verified primary institutional domain and uses a multi-source data architecture rather than search rankings from any single provider. A well-managed migration keeps an institution's web presence connected; a poorly managed one can temporarily fragment the signals that web-impact analysis observes. Universities should keep their new domain consistent across all official records.
