Intro
In January 2024, a well-loved indie blog that had closed in 2018 came back from the dead. Same domain, same backlinks, brand new content: a stream of AI clickbait. The new owner told Wired he bought it for its great reputation and excellent backlinks.
That sentence is Google's definition of expired domain abuse, almost word for word. And yet buying an expired domain is completely allowed. Done right, a strong, relevant old domain is one of the most powerful link sources there is. So where exactly is the line?
Allowed vs abuse
Claim number one. Expired domains are banned, and buying one is asking for a penalty.
Placebo. When Google launched its expired domain abuse policy in March 2024, it drew the line in one sentence: it's fine to use an old domain name for a new, original site designed to serve people first. Buying isn't the violation. What you do next is.
The abuse, in Google's words, is buying a domain and repurposing it mainly to manipulate rankings with content that gives users little to no value. Google's own example: a domain that used to belong to a medical site, now hosting low quality casino content, hoping to rank on the old owner's reputation.
The current spam policy gives three examples, and they share one shape. Affiliate content on a former government agency site. Commercial medical products on a former medical charity site. Casino content on a former elementary school site. Every time, the new content has nothing to do with the reputation it borrowed.
Google also wrote something pointed about who does this. Expired domain abuse isn't something people do by accident. These domains, it said, are generally not meant to be found any way except through search engines. In other words, nobody is typing the name of a dead school into their browser to buy casino chips.
Why does Google care this much? Think about the searcher. Someone clicks a result on a domain they remember as a school or a charity, and lands on pills. The reputation that earned the ranking belonged to someone else, and the person searching is the one who gets fooled.
Why the right domain is powerful
Now the side most channels skip. A relevant expired domain with genuinely strong links can be one of the best link sources that exists. Those links were earned editorially, years ago, from real sites. Moved surgically into a closely related site, that power can lift rankings in a way few other sources match.
That's our field work: we've seen it lift rankings on real campaigns when the domain is strong, the topic genuinely bridges and the move is done with precision. You won't get the setup, the counts or the timing from us. As we said last episode, a published recipe becomes a footprint.
So what does strong mean? Not a number in a tool. It means links from real, independent sites that chose to link years ago, on pages that still exist and still get crawled, about a topic close to yours. A domain with a huge authority score built from spam blogs isn't strong. It's wearing a costume.
Why does it work? Because redirects carry signals. Google's documentation says a permanent redirect tells its indexing pipeline the target should be canonical. Its site move guide says keeping redirects in place lets Google transfer signals to the new URLs, including links from other sites. Earned links keep their value when they point somewhere that makes sense.
And here's a detail from the 2024 leak. Google's anchor records include a field that's true when a link comes from an expired domain. The leak shows what Google stores, not how much it weighs. But it does mean Google keeps track of which links arrived through an old domain, so assume someone is looking at how you use them.
Where does the precision come in? The redirect itself is the easy part, a few lines of server config. The hard part is every judgement around it: which domain, which pages, where each one lands, and what your profile looks like once it's all joined. That's why two people can buy the same kind of domain and get opposite results.
Relevance has to bridge
Which brings us to the rule that decides everything. Relevance has to bridge from the source to the target. A dead film review blog, linked by film magazines, bridges naturally to ReelRadar. An expired recipe blog doesn't, no matter how good it looks in a backlink tool. A strong soufflé still isn't a film credential.
Even outside the policy, a careless redirect wastes value. Google's help pages say that sending users to another page, like the homepage, instead of returning a not-found error can be treated as a soft 404. In plain words: a redirect that lands somewhere unrelated may be read as a page that simply died.
What about the in-between cases? Say a dead TV review blog and ReelRadar's streaming guides. Close, not identical, so use the reader test. If someone followed an old link to that blog and landed on the new page, would they feel they ended up in the right place, or would they feel tricked? If it's tricked, don't.
Relevance works page by page too. An old review of a classic horror film has an obvious new home: ReelRadar's page for that film. The old blog's contest announcements have no home at all. Matching each valuable old page to a genuine counterpart is where most of the craft lives.
This is also why buying a related site and merging it is ordinary business. A film site buys a smaller film blog, moves its best articles over, and redirects each old page to that article's new home. Companies do this every day. It's the same principle with nothing to hide: a real site's history joining a related one.
Claim number three. Any 301 passes full power, so it doesn't matter where it points.
Placebo. A redirect passes signals when it's a real move to an equivalent page. Point it at a homepage and it can be treated as a soft 404. Point a bought domain at an unrelated topic and you've drawn Google's abuse example yourself. The leak even has a field called anchor mismatch demotion: its exact job isn't documented, but the name doesn't sound friendly.
Why most buys fail
So why do most expired domain buys go wrong? Spam history: plenty of good domains spent a few years selling pills before they reached the auction. Irrelevant topics, bought because a tool showed a big number. Dead links, pointing at pages that vanished years ago. And lazy redirects, everything dumped on a homepage.
Here's the classic version, starring ReelRadar. The team finds an expired domain with a lovely authority score and a price that feels like a bargain. Then someone reads the archive. It was a wedding photography blog, linked by wedding venues and florists. Lovely links, wrong party, and for a film site a very expensive bouquet.
Price tells you something too. Strong, relevant expired domains are rare, and the people who know their value compete for them. If a domain with an impressive profile on exactly your topic is cheap, ask why. The answer is usually in its history, and the archive will show you.
Then there's the rebuild trap. Lots of buyers put the old domain back online with thin or mass-produced content and point links out of it. That's Google's example, and the Wired story, rebuilt by hand. If you revive an old site, it has to be a real site that serves people first, or you've built a policy violation with extra steps.
Claim number four. Aged domains rank faster, so an old domain gives a new site a head start just for being old.
Placebo, and pure folklore. Asked in April 2017 whether domain age matters for ranking, Google's search advocate answered with one word: no. The leak's host age field is described as a way to sandbox fresh spam, which is about new sites misbehaving, not old ones getting a bonus. Age alone does nothing. The links and reputation behind it are what count.
Vetting an old domain
Now the vetting, and it starts in the Wayback Machine. Read the domain's history like a biography. Was it about something close to your topic? Did it stay that way? Is there a chapter where it suddenly became pharma, casino, loans or spam in a language nobody on the site spoke?
Here are two fictional timelines side by side. The first is a film review blog that ran for years, slowed down and lapsed. It bridges to ReelRadar. The second started as a film blog, became a pharma spam site, then sat parked with ads. Same starting topic, completely different domain, and the second one is a walk-away.
Then the link profile. In a backlink tool, ignore the authority number and look at who actually links. Are they real sites on a related topic, and do the links still exist? Check the anchors too. Casino or foreign language anchors on an English film blog mean someone got there before you.
Watch for links built after the domain dropped. Some sellers pump a domain before auction by pointing fresh, cheap links at it, so the profile looks stronger than its history. Compare when the links appeared with when the site was actually alive. Links that arrived while the site was dead weren't earned by anyone.
And search the old name. A domain can carry baggage no backlink tool shows: a business that went bust owing money, a scam warning, a scandal. If people searching the old brand find complaints, congratulations, those complaints are now yours.
Finally, the day you buy it, verify it in Search Console. Google's site move guide says to clean up a recently purchased domain, including manual actions from the previous owner and leftover URL removals. Google's manual actions help page even has a section called But I just bought this site. Fix everything before the domain goes near your main site.
If a domain passes all that, you're holding something valuable, and the remaining risk is in how you use it. That part is precision work. The topic has to bridge, the pages have to map to real equivalents, and the move has to look like what it is: a real site's history joining a related one.
Wrap up
Here's the episode on one screen. Buying is allowed, relevance decides the value, and age on its own does nothing.
The short version. Abuse is about what you do after you buy. Relevance has to bridge, page by page. Vet the history, the links and the old name before you spend, and check Search Console the day it's yours.
