Do expired domains keep their backlinks? It matters because backlinks are assets, and you want to know what you inherit when you buy. The short answer: yes, the links remain in the backlink graph. What is uncertain is whether their ranking value transfers to you when the domain drops and you re-register it.
The mechanics are straightforward: when a domain expires and drops, the pointing links do not disappear. They exist as records in the backlink profiles of thousands of other sites. A backlink database like Ahrefs or Majestic will show them as pointing to the expired domain. But whether Google credits those links to your new use of the domain depends on two things: whether Google associates the links with you as the new owner, and whether the link value has persisted through the downtime.
How the transfer works when you buy at auction
If you buy an expired domain in an auction run by the registrar during its grace period, such as GoDaddy's expiry auction, the domain never drops. It moves directly to the buyer. The site may stay offline for a while unless you bring it back quickly, but the registration is continuous, so there is no drop and no gap in registration. Links are more likely to keep their value in that case, though nobody outside Google can say how much. A domain won in a DropCatch auction is different: it was caught at the drop, so it follows the drop-and-re-register case below.
The risk is what you do with it next. If you rebuild the domain without losing links, preserving the old URLs and setting up 301 redirects from the old content to your new pages, the link value flows forward. If you change the domain's purpose entirely or delete all the old pages, Google has reason to discount the links as no longer relevant.
Domains that drop and re-register
When a domain fully expires and enters the redemption period (30 days in ICANN terms), then pending delete (5 days), then drops and becomes available first-come first-served, the situation is different. There is a gap. During those weeks, the domain is offline, and Google may have removed its pages from the index.
When you re-register it, the registration is technically new. Google representatives have said that domain age by itself is not a ranking factor and that there is no "sandbox" as such, but Google has not published how a drop and re-registration affects the value of old links.
In practice, you should assume the link value may be reduced rather than fully intact. Suppose a domain with 50 referring domains and DR 30 drops and is re-registered: its metrics in the backlink tools may come back lower at first. With fresh content and new inbound links to the live pages, they can recover, but there is no guarantee.
What Google has actually said about resetting
Google's March 2024 expired domain abuse policy does not address link value resetting. It covers content abuse: buying a domain and using it for low-value content in a different topic. Google defines it as follows: "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."
Using an old domain for a new, genuinely useful site is not covered by the policy. Still, a domain's past can matter. If it was penalized (for example a manual action), a new owner cannot see that in any public tool: manual actions are visible only to the verified owner in Search Console. hunter.domains cannot see manual actions either.
About domain age itself, Google representatives have said repeatedly that it is not a ranking factor by itself. So the benefit of an aged domain is not age, but the links attached to it.
Why links decay
Backlinks can lose value over time even without a domain expiring. A link from a site that has pivoted topics becomes less topically relevant, and linking pages get removed or changed.
On an expired domain, the links may be worth less sooner. The domain goes offline, so the links point to nowhere (a 404 error or a parked page), and links to dead pages are unlikely to help you. When you bring the domain back and restore content, those links can start to count again as they point to live pages.
Recovery is not instant or guaranteed. Measure the improvement by checking the domain's Ahrefs DR, referring domains, and rank for branded keywords in the weeks and months after you republish.
Keeping the link value: topic and URL continuity
The strongest way to retain the value of old links is to keep the domain's topic and use the same URLs. If the domain was about gardening tools and you restore it as a gardening site with the same URL structure, the links from gardening blogs remain relevant.
If you change the topic entirely, say from a gardening site to a financial site, the links become off-topic. The anchor text of incoming links (e.g., "best pruning shears") no longer matches the new content, and those links are likely to be worth much less.
If you use different URLs but the same topic, you will need 301 redirects from the old pages to the new ones to preserve the link juice. Without redirects, the old links point to dead pages, and you get no benefit.
The most conservative choice: restore the domain from the Wayback Machine, keeping the old content in place and the old URLs intact. You can then add new content alongside it. This minimizes the risk of signaling a topic change.
Measuring what you are inheriting
Before buying an expired domain, check its backlink profile. Pull the domain into Ahrefs, Majestic, or Semrush and note the referring domains, their anchor text, and their topics. Look for clusters: are most links from irrelevant blogs, or from on-topic, high-authority sites?
Check the Wayback Machine for the domain's history. What was it used for, and how long? If the domain has 10 years of history in gardening but you plan to use it for finance, those links will not help you.
Look at the archive's HTML titles and meta descriptions to spot topic changes or spam signals. If a domain had three different topics across its history, the link profile is fragmented, and value is lower.
Hunter.domains lists expired domains with full scoring and archive history for you to vet before buying. The Hunter score is built from Ahrefs DR, Majestic TF, referring domains, archive history, Semrush Authority Score, Open PageRank, price and age. Use the aged domains collection to find older domains, or check the full archive of ended domains to research specific domains you are considering.
Frequently asked questions
Do backlinks disappear when a domain drops?
No. The links remain as pointing records in other sites' backlink profiles. They do not vanish from the internet. However, they may be worth less to search engines while the destination domain is offline.
Does a dropped domain's authority reset?
Not entirely, but it is reduced. When a domain drops and goes offline, its pages can fall out of the index. When you re-register it, the registration is new and the history has a gap. The domain's Ahrefs DR, referring domain count, and other metrics may fall from their former peak. As you add fresh, on-topic content, these metrics can recover over time, but that is not guaranteed.
How long do old links keep working?
This depends on the search engine and the relevance of the link. Links from on-topic, high-authority sites typically retain their value longer. Links from low-authority or off-topic sites decay faster. Google does not publish a specific duration, so treat any number you read elsewhere as an estimate.
