What the policy actually says
Google's spam policies define the violation in one sentence: “Expired domain abuse is where an expired domain name is purchased and repurposed primarily to manipulate search rankings by hosting content that provides little to no value to users.”
Two words carry the weight. Primarily makes this a test of purpose rather than of method, and little to no value supplies the second limb. A domain purchase is not the violation, and neither is an unusual backlink profile. A domain purchase made in order to inherit ranking signals, then filled with content nobody had any reason to want, is.
That matters because the aged-domain market sells the opposite proposition. The pitch is that authority accrued by a previous owner can be bought and redirected to a new commercial purpose. Google's policy is a direct statement that it treats this as spam whenever the content does not stand on its own merits.
It is worth noticing what the definition does not contain. There is no age threshold, no limit on how many expired domains one owner may hold, and no requirement that the previous site was reputable. The policy is indifferent to all of that and interested only in why the purchase was made and what went up afterwards.
Purpose is difficult to observe directly, which is presumably why the published examples do so much of the work. They describe situations where the mismatch between a domain's history and its new contents is so complete that intent can be read off the page.
The three examples, and what they have in common
Google illustrates the policy with three cases: affiliate content published on a former government site, commercial medical products on a domain that used to belong to a nonprofit charity, and casino content on what was once a school website.
Each is a reputation transplant. In every example the incoming content has no relationship to whatever earned the domain its standing, and in every example the previous owner was the kind of institution whose links and citations cannot be acquired honestly at speed — government, charity, education. The mismatch is the evidence.
The choice of previous owners is not incidental. Those three categories attract exactly the sort of editorial links that cannot be bought at any price, which is what makes their lapsed domains valuable to someone who wants the signals without the institution.
The examples are deliberately extreme, which is a limitation worth naming rather than glossing. They do not tell you where the boundary sits for a genuine business that acquires a defunct competitor's domain, keeps the subject matter, and publishes real work on it.
Read conservatively, the common thread is topical discontinuity plus thin content. A buyer who preserves neither the subject nor the standard of the original site is describing Google's examples back to it.
The carve-out is explicit
Google's announcement of the policy states that it is fine to use an old domain name for a new, original site that is designed to serve people first.
This is unusually direct for a spam policy. It means the mere fact of buying an expired domain carries no penalty, and that a site which would rank on its own merits does not become spam because of its address history.
The practical distinction is whether the content would exist if the domain had no history at all. If the answer is yes, the policy is not aimed at you, however aged the address happens to be. If the only reason those pages were commissioned is the backlink profile attached to the domain, then the purpose test is satisfied and the policy is.
That test is useful precisely because it is answerable internally. A publisher can ask whether the editorial plan was written before or after the domain was acquired, and the answer is usually unambiguous.
None of which makes the inherited signals durable. A carve-out for legitimate reuse is not a promise that the previous owner's authority transfers — only that reusing the name is not itself an offence.
How it differs from the two policies announced alongside it
Three policies were introduced together, and they are frequently conflated. Scaled content abuse is about producing many pages primarily to manipulate rankings rather than to help users. Site reputation abuse is about third-party content published on a host site mainly to exploit ranking signals the host earned with its own first-party work.
Expired domain abuse is the third shape: not many pages, and not someone else's pages on your site, but your pages on someone else's former address.
Google's wording on site reputation abuse is careful in a way that matters here. The policy applies where third-party content is published on a host “mainly because of that host's already-established ranking signals”, and Google states that hosting third-party content is not by itself a violation.
For a company buying coverage, site reputation abuse is the policy that bears on placement directly, and we treat it separately. Expired domain abuse bears on a different purchase — the domain itself — and is far more likely to concern an agency's own asset portfolio than a client's press coverage.
The distinction collapses in one scenario worth flagging: an expired domain revived specifically to host paid third-party articles engages both policies at once, since the address was bought for its signals and the content is someone else's.
Google Search Essentials spam policies, as published 19 September 2026

Bars are equal because this chart classifies rather than measures. All three policies turn on whether earned signals are being transferred to content that did not earn them.
What this means for anyone buying authority
The through-line across all three policies is that Google is targeting the transfer of earned signals to unearned content. A domain's history, a publisher's reputation and the sheer volume of pages are treated the same way: as things that cannot substitute for the content being worth publishing.
That is an uncomfortable finding for parts of this industry, including parts adjacent to what we sell. Anyone offering an aged domain as a shortcut to authority is offering something Google has named as a violation and says it acts on.
It also reframes what due diligence on a domain purchase looks like. The question is not only what the backlink profile shows, but whether the new site will be recognisably about the same thing, produced to a standard that would survive on a new domain.
The defensible version is unglamorous: buy the domain if you want the name, then publish work that would earn its own standing. Where the plan depends on the previous owner's reputation, the plan is the thing Google describes.
For clients, the practical advice is narrower still. If a vendor's proposal involves publishing your coverage on a recently acquired expired domain, that is worth knowing before the invoice, because the risk sits on the asset rather than on the article.
The due-diligence question a buyer can actually answer
Because the policy turns on purpose, the useful diligence is not forensic but documentary. A buyer can ask, and answer in writing, whether the editorial plan for a domain existed before the domain was identified.
That single question separates the two cases Google describes. A publisher who planned a title and then went looking for a suitable name is in the carve-out. A buyer who found a domain with strong signals and then commissioned content to sit on it is describing the violation.
The second question is topical continuity. Where the new site covers roughly what the old one covered, to a comparable standard, none of Google's three examples fits. Where the subject changes completely — charity to commerce, school to casino — the examples fit closely.
The third is whether the content would survive on a new domain. If the pages would rank on their merits given time, the inherited signals are an accelerant rather than the point, and the policy's primarily test is not met.
None of these is a safe harbour, and Google publishes no scoring system. They are simply the questions the published wording makes relevant, and a buyer who cannot answer them comfortably should assume the policy is aimed at the transaction.
Methodology and limitations
The definition and the three examples are quoted from Google's Search Essentials spam policies page, retrieved 19 September 2026, which carried a last-updated stamp of 28 August 2026. We attempted three times to retrieve the text of Google's March 2024 Search Central announcement directly; the developers.google.com blog URL returned only archive navigation on two attempts and a mirror returned HTTP 403. The enforcement details in this report — that action began in March 2024, that it runs through both algorithmic systems and manual actions, that notice arrives through Search Console, and the statement that reusing an old domain for a new original site is fine — are therefore reported from that announcement rather than quoted from a page we retrieved ourselves. We have not tested enforcement, measured any site, or attempted to reproduce a manual action.
Conclusion
Expired domain abuse is a narrow policy with a clear target: buying a domain in order to inherit its ranking signals and filling it with content that would not otherwise merit them. Google's own wording makes the test one of purpose, and states explicitly that reusing an old domain for a genuine new site is permitted. For buyers of authority the useful conclusion is the one that runs through all three policies announced together — earned signals are not transferable to unearned content, whether the vehicle is a domain, a host publisher's subfolder, or volume.
Frequently Asked Questions
Is buying an expired domain against Google's rules?
No. Google states that using an old domain name for a new, original site designed to serve people first is fine. The violation is buying the domain primarily to manipulate rankings with content of little or no value.
Does an aged domain still pass authority?
Google's policy does not say signals stop existing; it says repurposing a domain primarily to exploit them is spam and is acted on. Treating domain age as a purchasable ranking asset is precisely the behaviour the policy names.
How would I know if a site was penalised for this?
Manual actions are notified in Google Search Console, and a reconsideration request can be filed. Algorithmic suppression carries no notification, which is why the absence of a message is not evidence of compliance.
Is this the same as site reputation abuse?
No. Site reputation abuse covers third-party content hosted on a publisher that earned its signals with first-party work — the policy that bears on sponsored placement. Expired domain abuse covers content published on a domain whose reputation a previous owner earned.
Does redirecting an expired domain to my site count?
Google's published examples all describe hosting content on the repurposed domain rather than redirecting it. The policy text does not resolve redirects explicitly, and we will not extrapolate beyond what Google has written.
Does this policy apply to domains I already own?
The policy is written about domains that are purchased and repurposed. A domain you have held and published on continuously is not the scenario Google describes, though the scaled content and site reputation policies may still apply to what you publish on it.
