How to Check Domain Age (and What It Tells You)
Updated 11 September 2026 · 6 min read
Domain age is how long a domain name has been registered, measured from the creation date in its registration record. It's easy to look up, and it's useful in a few specific situations, but it's also one of the most misunderstood numbers in SEO.
This guide shows you how to check a domain's age, how to read the dates in a registration record, why an old creation date can be misleading, and when domain age is genuinely worth checking.
What domain age actually measures
When someone registers a domain, the registry records a creation date. Domain age is simply the time between that date and today.
It's important to be precise about what this is not:
- It's not the age of the website. A domain can sit unused for years before anyone builds a site on it.
- It's not the length of current ownership. Domains can change hands many times without the creation date changing.
- It's not always the domain's first registration. If a domain expired, was deleted, and was registered again, the creation date usually reflects the new registration.
How to check domain age
Use a domain age tool
The quickest way is our Domain Age Checker. Enter a domain and it shows the creation date and the calculated age, along with the expiry date where the registry publishes it.
Look up the registration record
For the full record, use our WHOIS Lookup, or ICANN's own lookup at lookup.icann.org, which queries registration data for domains under generic top-level domains like .com, .net and .org.
Both rely on two protocols:
- WHOIS is the original protocol for registration data. It returns plain text, and every registry formats it slightly differently.
- RDAP (Registration Data Access Protocol) is its modern replacement. It returns structured JSON, which makes dates far easier to read reliably. ICANN requires RDAP for generic top-level domains.
Reading an RDAP response
RDAP responses, defined in RFC 9083, list dates in an events array. A trimmed example:
{
"objectClassName": "domain",
"ldhName": "EXAMPLE-SHOP.COM",
"events": [
{ "eventAction": "registration", "eventDate": "2011-03-14T18:22:05Z" },
{ "eventAction": "expiration", "eventDate": "2027-03-14T18:22:05Z" },
{ "eventAction": "last changed", "eventDate": "2026-02-02T09:10:44Z" }
]
}
What each date means:
- registration is the creation date. This is what domain age is calculated from. In this example, the domain was registered in March 2011.
- expiration is when the current registration period ends. The owner can renew before then.
- last changed is the last time the record was updated. This can be triggered by a renewal, a nameserver change, a contact update or a transfer. It doesn't necessarily mean the domain changed owners.
In older WHOIS text output, the same dates usually appear as Creation Date, Registry Expiry Date and Updated Date.
Why an old creation date can mislead you
Re-registration resets the clock
When a domain isn't renewed, it goes through grace and redemption periods and is eventually deleted. Anyone can then register it as new. That new registration gets a new creation date. So a domain with a 2024 creation date may have hosted a website in 2012 under a different owner.
Transfers don't reset the clock
The reverse is also true. If a domain is renewed continuously while being sold or transferred between registrars, the creation date stays the same. A domain registered in 2005 and bought last month still shows 2005. An old date tells you the registration is old, not that the current owner has been running the site for years.
Country-code domains vary
Registries for country-code top-level domains, such as .uk, .de or .pk, set their own policies. Some publish full dates, some publish less, and some don't show a creation date publicly at all. If a lookup returns no date, that's usually a registry policy, not an error.
Domain age versus site history
For most real decisions, what you want to know is the history of the site, not just the registration date. Two things help:
- Archived snapshots. The Internet Archive's Wayback Machine shows how a site looked at different times. Check whether the domain was always about the same subject, whether it went through periods of spam or unrelated content, and whether there's a gap where it may have been dropped and re-registered.
- Current and past DNS and hosting clues. Nameservers, mail records and the technology the site runs on can tell you whether it's an active business. Our DNS records explained guide covers what to look for.
If the registration date says 2009 but the first archived snapshot with real content is from last year, the domain's age isn't telling you much about the site.
Does domain age affect rankings?
Google representatives have said publicly on several occasions that domain age by itself isn't something Google's ranking systems use. That matches how search works in practice: a brand-new domain with excellent content can rank, and an old domain with thin content won't.
The confusion comes from correlation. Older sites have had more time to publish content, earn links and build a reputation, and those things do matter. The age is incidental. Buying an old domain doesn't transfer any of that history if the content and links aren't relevant to what you plan to publish.
When domain age is worth checking
Buying a domain, especially an expired one
This is where domain age and history matter most. Before you buy:
- Check the creation date and registration events to understand whether it was held continuously or dropped.
- Review archived snapshots to see what the domain was used for.
- Check for existing backlinks, and whether they're relevant or spammy. See how to check backlinks.
- Search for the domain name to see whether it's associated with spam or complaints.
- Plan to use it for a closely related purpose. Google's spam policies describe "expired domain abuse": buying an expired domain and using it to host unrelated, low-value content in order to benefit from its past reputation. Examples Google gives include affiliate content on a former government site and casino content on an old school's domain.
Vetting sites you work with
When choosing guest post sites or partners, a domain registered a few weeks ago that claims years of publishing history is worth a closer look. The registration date isn't proof of anything, but a mismatch between claims and records is a reason to ask questions.
Spotting suspicious sites
Scam and phishing sites are frequently set up on newly registered domains, because they tend to be shut down quickly. A very recent creation date on a site asking for payment or login details is a reason for extra caution, alongside other checks such as the site's contact details and SSL certificate. See how to find who owns a domain.
Checking business claims
A company that says it has been online since the early 2000s but whose domain was created last year may have simply moved domains, which is common. But if it matters to you, ask.
A quick step-by-step
- Enter the domain in the Domain Age Checker and note the creation date.
- Open the full record with the WHOIS Lookup and check the registration, expiration and last-changed dates.
- Look at the earliest and most recent archived snapshots of the site.
- Compare the timeline with what the site claims about itself.
- If you're buying the domain, review its backlinks and past content before paying.
The short version
Domain age is the time since a domain's current registration was created. It's easy to check with RDAP or WHOIS, but it resets on re-registration, doesn't change on sale, and says nothing on its own about the site's quality. Use it as one piece of due diligence, particularly when buying domains or vetting sites, and pair it with the site's actual history before drawing conclusions.
