Buying Expired Domains for SEO: What Works and What Google Penalises (2026)
What buying an expired domain actually gets you, the three ways to acquire one and what each costs, Google's expired domain abuse policy quoted in full, and the rebuild-or-redirect decision that decides whether the links count.
People buy expired domains for SEO because a domain that ran a real site for years still has pages on other sites linking to it, and a brand-new domain has nothing. That part is true. Most of what gets written around it is not, and the gap between the two is where money goes missing. This guide is what an expired domain actually gives you, how you get one, what Google's policy says word for word, and the decision after purchase that decides whether any of it works.
One clarification first, because the phrase "buy an expired domain" hides three different transactions. You can win one at a registrar's expiry auction before it drops. You can pay a backorder service to catch it the instant it drops. Or you can register it yourself at the normal price, after it has dropped and nobody caught it. We run a directory that lists domains in that third state. We do not sell them, hold them or register them for you. Wherever this guide says "buy", read the transaction that applies.
Why do people buy expired domains for SEO?
Three things can survive a domain expiring. Backlinks, history and age. None of them survives automatically, and they matter in that order.
Backlinks are links from pages on other sites. They stay where they are when a domain drops, so the next registrant gets the same inbound links. That is the entire asset, and whether it is worth anything depends on who placed each link and why. A citation from a university department or a trade publication is a different thing from three hundred directory listings, even though both show up as a count.
History is the archived record of what the domain published. A domain that was a veterinary practice for twelve years has twelve years of evidence about what it is a plausible source for. That record is what a search engine or an answer engine has to go on when it decides whether the domain fits what you put on it.
Age is the weakest of the three. Hard to fake, easy to overrate. Google has never said age is a ranking factor, and aged domain vs new domain goes through what is actually known.
What none of this gives you is a shortcut. The links point at pages that no longer exist, under a subject you may not share. The rest of this guide is about closing that gap or deciding not to try.
Is buying expired domains for SEO against Google's rules?
Not by itself. Google's spam policies added a section on expired domain abuse in March 2024, and it is short enough to quote in full:
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. Illustrative examples include, but aren't limited to:
Affiliate content on a site previously used by a government agency
Commercial medical products being sold on a site previously used by a non-profit medical charity
Casino-related content on a former elementary school site
The announcement post from the same day is more direct about who the policy is aimed at: "Expired domain abuse isn't something people accidentally do. It's a practice employed by people who hope to rank well in Search with low-value content by using the past reputation of a domain name." And then the sentence that matters if you are doing this in good faith: "It's fine to use an old domain name for a new, original site that's designed to serve people first."
Read the three examples again. Each one is a mismatch between what the domain was and what it became, plus content that exists to rank rather than to be read. Both halves are in the definition. A school domain turned into a casino affiliate fails on fit. A gardening domain relaunched as a thin gardening affiliate site fails on value. A gardening domain relaunched as a good gardening site fails on neither, and Google says so in the announcement.
We quote the whole policy, the 2020 and 2024 statements from Google staff and a two-part fit test in expired domain abuse: what Google's policy actually says. If you read one other thing before buying, read that.
How do you actually buy one?
| Route | When | Typical cost | What you get |
|---|---|---|---|
| Registrar auction | Before the domain drops | Bids from about $10 to thousands | Registration transfers, no gap in history |
| Backorder | The instant it drops | Fee per catch, auction if contested | A chance, not a guarantee |
| Direct registration | After it drops, if uncaught | Normal registration price | The domain, if you got there first |
The timeline behind those three rows is set by ICANN's Expired Registration Recovery Policy and the registry contracts. For a .com the path from expiry to drop runs somewhere between about 35 and 80 days, with a 30-day redemption period during which nobody but the previous owner can touch it. The complete guide to expired domains has the stage-by-stage table.
Auctions get the strongest names, because the registrar lists them before they can drop and the bidding tracks the link count. Backorders are a race between services that hold dozens of registrar accreditations, and dropcatching explained covers why the ordinary person rarely wins one for a contested name. Direct registration is what is left, and what is left is more than people assume, because the auction and backorder filters run on crude metrics and skip anything they cannot score.
That last category is what the Revised directory lists. Every entry has already dropped, has inbound links we verified, has had its archive screened, and carries the date we last confirmed it was still unregistered. You reveal the name and register it yourself at any registrar for the normal price.
What should you check before you pay?
Cheapest check first. Stop at the first failure.
Availability and history come from the expired domain checker. It tells you whether the name is registered now, when the Wayback Machine first saw it, how many snapshots exist and what the site was about in each era. Then open the Wayback Machine and click through snapshots yourself at three or four points in the domain's life. You are looking for one subject over years and for the stretch, usually the last one, where it stopped being that.
Links come from the backlink checker, which lists the source page, anchor text and link type for each referring domain in our Common Crawl index. Read the referring domains as a list of names before you read any number. Then check the anchors. Google's guidance on qualifying outbound links says links marked nofollow, sponsored or ugc "will generally not be followed", so a profile that is mostly forum signatures and comment links is a profile Google has been told to discount.
The domain authority checker is last, as a sort key. Across the Revised directory, a high referring-domain count correlates with a lower authority score, not a higher one. The domains with hundreds of linking sites are mostly the ones that were spammed at some point. If the score and the count disagree, believe the score, then go and read the links anyway.
A trademark search is the check everyone skips. A domain that was a company's brand name may still be that company's brand name, and a demand letter costs more than the domain did. The full order of operations, with the checks that have caught the most bad domains for us, is in how to evaluate an expired domain's link history.
Should you rebuild the site or redirect the domain?
This is the decision that decides whether the links count, and it is usually made in the wrong order, after the purchase instead of before.
| Option | What the linking pages see | Fits the abuse policy when | Effort |
|---|---|---|---|
| Rebuild the site | The subject they linked to, updated | The new site serves the old subject | Weeks of real content |
| Redirect | A different site, on your domain | The target is on the same subject | An afternoon, then waiting |
| Do nothing | A parking page | Never a problem, never a benefit | None |
Rebuilding means putting a real site back on the domain, in the subject the linking pages were pointing at, with the linked URLs resolving again. It is the option the announcement post explicitly blesses, and it is the only one where every link keeps pointing at something relevant. Rebuilding an expired domain's website is the practical guide, including how to recover the old page structure from the archive.
Redirecting means pointing the domain at a site you already run. Google's redirect documentation says of a permanent redirect that "Googlebot follows the redirect, and the indexing pipeline uses the redirect as a signal that the redirect target should be canonical." Nothing in that documentation promises the target inherits anything. In practice a redirect makes sense when the old domain and the new site cover the same subject and the linking pages would still be sending readers somewhere sensible. When they would not, you have built the first example in the abuse policy with an extra HTTP hop. Redirecting expired domains covers the cases where it holds up and the more common ones where it does not.
What does it cost, honestly?
The domain is the small part. A direct registration is the normal price for the TLD, which for a .com is around $10 to $15 a year at most registrars. An auction win for a name with a visible link profile runs from tens of dollars into the thousands, and the price tracks the referring-domain count, which we have already said is a weak signal.
Evaluation is hours, not minutes. Reading the archive, reading the linking pages, checking the trademark register. Rebuilding is weeks, because a domain with no content is a domain with nothing for the links to point at. And there is a failure rate nobody publishes. Some domains that pass every check never do anything, and we do not have a clean explanation for which ones. Budget for that, and never pay more for a domain than you would be content to have wasted.
FAQ
Is buying expired domains for SEO worth it? When the domain's history matches what you intend to build and the links come from pages a person chose to write, yes, because you start with citations a new domain would take years to earn. When either half is missing, the links point at nothing relevant and the purchase is a name at a markup.
Does Google penalise expired domains? Google penalises expired domain abuse, which its spam policies define as repurposing an expired domain "primarily to manipulate search rankings by hosting content that provides little to no value to users". The same announcement says an old domain with "a new, original site that's designed to serve people first" is fine.
Can I redirect an expired domain to my site? You can, and Google's documentation treats a 301 as a canonicalisation signal, not a transfer of anything. It holds up when the old domain and the target share a subject. When they do not, it matches the abuse policy's own examples.
How much do expired domains cost? A direct registration after the drop is the normal price for the TLD. Auction prices for names with links run from tens of dollars to several thousand, and are set by bidding on the referring-domain count rather than the quality of the links.
Where do I buy expired domains? Registrar auctions and backorder services for names that have not dropped yet. For names that already have, any registrar, once you know the name. The Revised directory lists dropped domains with verified links so you can find the name; the registration is yours to make.
When you are ready to look at real candidates, browse the directory of expired domains with backlinks. Filter by TLD, by aged domains or by authority, read the referring-domain band and the archive timeline on each listing, and reveal a name only once its history fits what you plan to build.
