# Does domain age affect SEO? What the data actually supports
> Domain age is not a Google ranking factor. Old domains rank better because they accumulated links and history, not because of age. A domain that lapsed and was re-registered has reset that history, so paying a premium for an aged domain buys the symptom rather than the cause.

Short answer: domain age is not a ranking factor, and old domains still tend to rank better. Both statements are true, and the gap between them is where a lot of money gets wasted on expired domains.
## What Google has actually said
Google's position has been consistent and specific: the age of a domain, by itself, carries no weight. What matters is what happened during those years.
That is not corporate deflection. Think about what a ten-year-old domain that has been actively used accumulates:
- **Links.** A decade of being referenced. This is the real ranking factor.
- **Content history.** Pages that have been crawled, evaluated and ranked repeatedly.
- **Brand signals.** People searching the brand name directly, which is a strong quality signal.
- **Crawl trust.** Googlebot visits established domains more often, so new pages get discovered and evaluated faster.
A domain registered in 2010 that has sat parked the entire time has none of these. It ranks exactly like a domain registered yesterday, because in every way that matters it *is* a domain registered yesterday.
Free tool: [Domain Age Checker](https://rankcert.com/tools/domain-age-checker) - Find out exactly how old a domain is, when it was registered, when it was last changed and when it expires.
## The confounding variable
Studies that find a correlation between domain age and rankings are almost always measuring links. Old domains have more links because they have had more time to acquire them. Control for referring domains and the age correlation largely disappears.
This matters practically. If you are choosing between spending $3,000 on a ten-year-old domain and $3,000 on content and outreach for a new one, the second is a better investment nearly every time - because you are buying the thing that actually causes the ranking rather than a proxy for it.
## What "the sandbox" actually is
New sites often see months of near-zero traffic before anything moves. This gets attributed to a deliberate "sandbox" that penalises new domains. Google denies such a filter exists, and the observed behaviour has a simpler explanation:
- **Crawl frequency starts low.** A domain with no links gets discovered slowly and revisited rarely.
- **Nothing has been evaluated yet.** Ranking requires Google to have some basis for judging quality. That basis is behavioural and link data, which take months to accumulate.
- **Links take time to be counted.** A link you earn in month one may not be reflected in rankings for months.
The effect is real, the mechanism is not a penalty, and buying an aged domain does not skip it - because a re-registered domain's history is largely reset anyway.
## When an aged domain does help
There is one case where it genuinely does: buying a domain that is *still in use*, with a real, relevant link profile, and continuing in the same topic.
Buying a defunct competitor and redirecting it to your site can transfer meaningful value, because the links point at pages about your subject and the redirect preserves that relevance.
The failure mode is buying an aged domain about something unrelated. A ten-year-old domain that hosted a fishing blog, redirected to your SaaS, passes almost nothing - Google treats topically irrelevant redirects as soft 404s, and any accumulated value evaporates.
## What to check before buying
Run these in order. Any failure is disqualifying.
1. **Actual registration date, from the registry.** Not "first seen in an archive" - that is a different number and usually later.
2. **Continuity.** Look for a gap between an old registration date and a recent "last changed". A domain that lapsed and was re-registered has reset.
3. **Archive history.** The Wayback Machine tells you what it was. Spam, adult content or a private blog network is a permanent liability, not a discount.
4. **Current index status.** Search `site:thedomain.com`. Zero results for a domain with a long history suggests a manual action.
5. **Link profile.** Not link count - referring *domains*, and whether they are relevant. Ten thousand links from three hundred spam domains is worse than nothing.
6. **Topical fit.** If you cannot continue the same subject, the links do not transfer.
The single most reliable tell: a registration date far in the past combined with a very recent "last changed" date and parked nameservers. That is a dropped domain being resold on the strength of an age number that no longer means anything.
## What to do instead
For nearly every new product, the better use of that budget:
- **A tool or dataset worth linking to.** One genuinely useful free tool earns links passively for years. That is what an aged domain's link profile is, built deliberately.
- **Original data.** A benchmark or survey nobody else has published is the most reliable link magnet available to a small team.
- **A handful of real editorial links.** Five relevant, editorially-given dofollow links beat five hundred directory submissions, and cost less than a premium domain.
Age is a symptom of having done these things for a long time. Buying the symptom does not give you the cause.
