What is expired domain abuse?
Expired domain abuse is buying a domain name that its previous owner let lapse, then reusing it mainly to rank low-value content on the strength of the old site's reputation. Google defines it as when "an expired domain name is purchased and repurposed primarily to manipulate search rankings by hosting content that provides little to no value to users" [1].
Google's own examples make the pattern clear [1]:
- Affiliate content on a site previously used by a government agency.
- Commercial medical products sold on a site previously used by a non-profit medical charity.
- Casino-related content on a former elementary school site.
In each example, the new content has nothing to do with what earned the domain its links and trust. The buyer is not continuing the old site. The buyer is renting its history to rank something unrelated.
Is buying an expired domain against Google's rules?
No. Buying an expired domain is not against Google's rules on its own. Expired domain abuse needs two things at once: the domain is repurposed "primarily to manipulate search rankings", and it hosts content "that provides little to no value to users" [1]. A business that buys a lapsed domain because the name fits its brand, and builds a genuine site on it, is not described by the policy.
The intent wording matters. Google's policy does not name a time limit, a link count or a topic rule that turns a purchase into abuse. It names a purpose. That means the same domain bought by two different people can be fine in one case and abuse in the other.
How does Google detect and treat expired domain abuse?
Google detects expired domain abuse the same way it detects other spam: through automated systems and, as needed, human review that can result in a manual action [1]. Google says sites that violate its spam policies "may rank lower in results or not appear in results at all" [1].
Google names SpamBrain as one of its spam detection systems and says these systems are updated to keep up with new spam tactics [4]. When Google makes a notable improvement to them, it calls that a spam update [5]. Google says a site can improve after changes "if our automated systems learn over a period of months that the site complies with our spam policies" [5].
Google has not published how it judges whether a domain changed hands, how much of an old domain's link history it keeps after a purchase, or how often the policy is enforced. Claims that Google "resets" an expired domain's backlinks on purchase are not something Google states in its policy. No published figure exists for how many domains are caught.
When did expired domain abuse become a Google spam policy?
Expired domain abuse became a named Google spam policy on March 5, 2024. Google added it in the same documentation update as scaled content abuse and site reputation abuse [2], which together form the set of spam policies Google introduced that year.
Before 2024: expired domains as a link spam tool
Buying expired domains for their links is an old tactic. Wikipedia's article on spamdexing describes link spammers using expired domain crawler software, or watching DNS records for domains about to expire, then buying them and replacing the pages with links to their own sites [3]. That use was already covered by Google's rules on link spam. What changed in 2024 was that the content use got its own name.
March 5, 2024: the policy is named
Google's documentation log records the addition of three new spam policies on March 5, 2024: expired domain abuse, scaled content abuse and site reputation abuse [2]. The same update added a help page on helpful content. In the same month, Google says its helpful content system became part of its core ranking systems [4].
2024 to 2026: wording unchanged
As of October 2026, Google's definition and its three examples of expired domain abuse are the same as the wording introduced in 2024 [1]. Search Insider found no later documentation entry changing the policy [2], unlike the site reputation policy, which Google has revised several times.
What is the difference between expired domain abuse and site reputation abuse?
Expired domain abuse exploits a domain's past, while site reputation abuse exploits a site's present. In expired domain abuse, the original owner is gone and the buyer controls the whole domain. In site reputation abuse, an active site with its own content hosts third-party pages mainly because of the host's ranking signals [1].
| Expired domain abuse | Site reputation abuse | |
|---|---|---|
| Who owns the domain | The new buyer | The active, established publisher |
| Whose reputation is borrowed | The previous owner's | The current host's |
| Is the original site still running? | No | Yes |
| Typical example | Casino content on a former school domain [1] | A "best casinos" page on a medical site [1] |
What is the difference between expired domain abuse and a PBN?
A private blog network is a set of sites one owner controls to send links to a main site, and it is often built from expired domains. Expired domain abuse is about the content placed on a repurposed domain. A PBN built on expired domains can break two policies at once: the link spam policy, for the links, and the expired domain abuse policy, if the domains carry low-value content mainly to rank. Search Insider does not support or suggest the use of PBNs.
Drop-catching, registering a domain the moment it is released, is a way of acquiring an expired domain. It describes the purchase, not what happens next, so drop-catching is not abuse by itself.
How do you check an expired domain before buying it?
To check an expired domain before buying it, compare what the domain used to be with what you plan to put on it. The closer the match, and the more real value the new site adds, the further the plan sits from Google's examples [1]. A practical check:
- Look at the old site. Use a web archive to see what the domain hosted and who ran it: a business, a charity, a school, a government body.
- Compare topics. If your plan is unrelated to the old site, like each of Google's three examples, you are close to the policy's pattern.
- Read the backlinks. Links that praise a charity or cite a school will now point at something else. Ask whether those linking sites would still link to your new content.
- Check for spam history. Look for a past life as a link network, scraped content or a sudden switch in language or niche.
- Be honest about the purpose. If the only reason to buy this domain instead of a fresh one is its existing rankings and links, that is the purpose the policy names.
What should you do if you own a repurposed expired domain?
If you own a repurposed expired domain, make sure the site would deserve to rank if it were brand new. Google's policy targets content "that provides little to no value to users" on a domain repurposed to manipulate rankings [1], so the fix is in the content and the purpose, not in hiding the domain's history.
If a manual action appears in Search Console, Google's Manual actions report lists the issue and lets the site owner submit a reconsideration request after fixing it [6]. If rankings drop after a spam update without a manual action, Google says recovery depends on its automated systems learning over months that the site now complies [5].
