Aristotle wrote that one swallow does not make a summer, nor does one day. He was arguing about happiness, but the line fits search results just as well. A swallow is a sign that summer is coming. It is not the summer.
Open the first page of almost any competitive search and you will find old websites. SEOs have asked the same question for years: does Google reward a domain for being old?
Google has been saying no since 2017. The more useful question is why old sites sit at the top anyway, and what that means if you are thinking of buying one. We sell aged domains, so you should know where this post lands. The evidence does not show that an old domain is a shortcut.
What Google has said about domain age
Here is the record, oldest first.
| Date | Who | What was said |
|---|---|---|
| 26 Oct 2010 | Matt Cutts, Google | In a Search Central video he said the gap between a 6-month-old domain and a 1-year-old one is small. He told people not to worry about buying pre-aged domains and to focus on content and links. He did not say age is not a signal. |
| 12 Apr 2017 | John Mueller, Google | Asked on Twitter whether domain age matters, he answered "no". |
| 5 Jul 2019 | John Mueller | Said domain age "helps nothing". The same day he wrote that content "doesn't get better automatically just because it's old". |
| Dec 2023 | John Mueller | Replying on X to a question about domain age and rankings, he joked that it matters "primarily" to "those who want to sell you aged domains". |
That last reply is aimed at businesses like ours, so we will not skip it. We read it as a fair warning about how age gets sold. The rest of this post tries to separate the part that is true from the sales line.
We found no Google documentation that lists domain age as a ranking signal. Google's March 2024 spam policy post does say that third-party "authority" and "reputation" scores "don't correspond to any of Google's own signals". It does not mention domain age, but it shows Google does not recognize the scores sold by SEO tools.
The patent people keep citing
The best-known source for the age theory is a Google patent application, US 2005/0071741, "Information retrieval based on historical data" (later granted as US 7,346,839). It was filed in 2003 and names Matt Cutts among its inventors. It says a document's inception date may be used to adjust its score, and that the date could come from when Google first indexed the document, when it first found a link to it, or when its domain was registered. It adds that older documents may suit some queries better than newer ones.
The same patent says valuable domains are often paid for years in advance, while throwaway ones rarely last past a year, so the expiry date might help predict whether a domain is legitimate. That passage is about spotting spam.
The inception-date section is about the age of a document, not a bonus for the age of a domain. A patent also describes what a system may do, not what Google runs today. In 2010 Cutts said the easy way to measure a domain's age is when Google first crawled it or first saw a link to it, and that WHOIS data is "not generally available".
Why old domains still dominate the results
The correlation exists, and the studies say so.
- Ahrefs, May 2025: across 1.3 million US keywords, 72.9% of top-10 pages were more than 3 years old, and 13.7% were under 1 year. This measures page age, not domain age. Ahrefs dates a page by when its crawler first saw it, which is not the same as the publish date.
- SE Ranking, May 2026: across 100,000 search results and 147,195 top-10 domains, 57.15% were 15 years old or more and 2.03% were under 2 years. The median age of a top-10 domain was 17.3 years. This is one snapshot from an SEO vendor, using its own trust metric.
The same SE Ranking study shows what travels with that age. Its 15+ year group had a median of 10,875 backlinks and 1,204 referring domains. Its 0 to 2 year group had 85 and 45. A small set of young "authority outliers", the top 2% of that group by referring domains, had 1,921 referring domains and ranked for more competitive queries. SE Ranking's conclusion is that age is mostly the visible pattern and authority explains it.
Plato gives us a picture for this. In the cave of the Republic, prisoners chained since childhood see only shadows on a wall and take them for the things themselves. Domain age is the shadow. The objects casting it are links earned over years, content that kept getting cited, and a long record of not being spam. If you buy the shadow without the objects, you have bought nothing.
What Google says about buying an expired domain
On 5 March 2024, Google announced its "expired domain abuse" spam policy. It defines this as buying an expired domain and repurposing it mainly to manipulate rankings, by hosting content that gives users little or no value. The policy page gives three examples: affiliate content on a former government site, medical products sold on a former medical charity's site, and casino content on a former elementary school site.
Two details matter if you are a buyer:
- The policy targets intent and value, not ownership. In the same March 2024 announcement, Google says it is fine to use an old domain name for a new, original site designed to serve people first.
- Sites that violate the policy may rank lower or not appear at all. A manual action would arrive as a notice in Search Console.
Mueller described the practical side in September 2025, answering a Reddit question about a new site on an expired domain. Sometimes it takes a lot of time, he wrote, for the old state of a domain to be shaken off. He added that there was nothing manual the owner could do.
That is the old puzzle of Theseus' ship. Plutarch tells us the Athenians kept the ship of Theseus for generations, replacing its old timbers as they went, until philosophers argued over whether it was still the same vessel. A domain that changes hands and has its content replaced plank by plank poses that question to Google's systems, and by Mueller's account they take time to answer it.
What to do if you are buying an aged domain
- Check the history before the age. Look at what the domain published before, using the Wayback Machine and a backlink tool. Our guide on how to check an aged domain before you buy it walks through it.
- Know what you are buying. If you are unsure how an expired domain differs from an aged one, read expired vs aged domain: which to buy.
- Build something useful on it. The spam policy targets sites that borrow a past reputation and give nothing back, and Google says original content made for people is fine. Matching the domain's old topic is our own rule of thumb, not Google's, but a topic that fits the history is easier to defend.
- Plan for a wait. Based on Mueller's 2025 comment, the old state of a domain can linger, so do not count on it carrying you.
- Ask the seller what is behind the number. An age in years tells you when a domain was registered. The links and the history tell you whether it is worth buying.
A new domain is not doomed either. In 2010 Cutts said a domain only needs to have been around "a couple months, a few months" to show up in results. Early in On the Shortness of Life, Seneca says we are not given too little time, we waste much of what we have. The same goes for a domain: the years already behind it matter less than what you publish on it from now on.
If you decide to buy, you can browse the aged domains we list.
Frequently asked questions
Does domain age matter for SEO?
Not as a direct ranking signal, according to Google's statements since 2017. Cutts played it down in 2010 but never said it was not a signal. Older domains tend to rank well because they usually have more links, more content and a longer record, and SE Ranking found those travel with age.
Is a 10-year-old domain better than a new one?
Only if its history is good. A 10-year-old domain with spam in its past or no links behind it has no edge. Young domains with very strong link profiles do reach the top 10, as the SE Ranking data shows.
Does registering a domain for 10 years help SEO?
Google staff have said they do not look at registration length as a ranking factor. The 2003 patent application mentions the expiry date only as a possible way to judge whether a domain is legitimate. Do not pay for a long registration expecting a ranking boost.
Is the Google sandbox real?
Mueller wrote in August 2019 that there is no sandbox. In February 2019 he said that for new pages there is no fixed rule or timeline. New sites often rank slowly, which is easier to explain by their having fewer links and less history, though that explanation is ours and not Google's.
Is buying an expired domain against Google's rules?
No. Buying one is allowed. Using it mainly to manipulate rankings with low-value content is what Google's expired domain abuse policy covers.
