What domain age means (and what it doesn't)

"How old is this domain?" has at least three different answers, and they often disagree. This guide explains each one, where the dates come from, and what Google has said about domain age and rankings.

Three different "ages"

• Registration date. When the current registration of the name was created at the registry. This is what most people mean by domain age.
• First website. When the name first pointed at a working site. Nothing in the registration record tells you this.
• First archive capture. The earliest copy of the site held by the Internet Archive's Wayback Machine. It's a clue to when a site existed, not its launch date. The Internet Archive says sites can be missing because its crawlers didn't know about them, they were blocked by robots.txt or a password, or the owner asked to be excluded (Wayback Machine help).

A domain can have a recent registration date but archive captures going back years. That usually means the name lapsed and someone registered it again (see below).

How RDAP shows registration dates

Registration data is now published through RDAP (Registration Data Access Protocol), which ICANN calls the replacement for WHOIS. Since 28 January 2025, registries and registrars for generic top-level domains (gTLDs such as .com) no longer have to run WHOIS, apart from a few exceptions (ICANN on RDAP). IANA's RDAP bootstrap file lists the RDAP server for each TLD that has one. Some country-code registries are included, such as Nominet for .uk, but not all of them. For some names there may be no RDAP record to show.

An RDAP response includes an events list, and each event has an action and a date (RFC 9083). The meanings are set out in IANA's RDAP values registry:

• registration – "The object instance was initially registered." This is the registration date.
• expiration – the date the registration will be removed, or was removed, unless it is renewed.
• last changed – when the record's information last changed. It doesn't say what changed: it could be a renewal, new nameservers or new contact details.
• transfer – the domain moved from one registrar to another.
• last update of RDAP database – when the RDAP server last synced from the registry. It's not a change to the domain.
• registrar expiration – the expiry date held by the registrar, which can differ from the registry's date.

A shortened example (illustrative dates, not a real record) looks like this:

"events": [
  { "eventAction": "registration", "eventDate": "2009-03-02T10:15:00Z" },
  { "eventAction": "last changed", "eventDate": "2026-02-20T08:01:12Z" },
  { "eventAction": "expiration",   "eventDate": "2027-03-02T10:15:00Z" }
]

The Registration panel in your Domain Statistics report shows the registration, expiry and last-changed dates and the registrar, all taken from RDAP.

Why a dropped domain loses its age

At the registry, a domain is a record. The EPP standard used by registries defines the creation date as "the date and time of domain object creation", and each object gets a repository ID when it is created (RFC 5731). If a registration expires and is deleted, that record goes. Whoever registers the name next creates a new one, so the registration date starts again from that day.

How long that takes depends on the registry:

• gTLDs (.com, .org and others). After a registrar deletes an expired name, it goes into a 30-day Redemption Grace Period. During that time the registry must disable DNS resolution, but the registrant can still restore the name (ICANN ERRP). If nobody restores it, it spends 5 days in pendingDelete and is then released for registration on a first-come, first-served basis (ICANN expiry FAQ).
• .uk. For 30 days after expiry the domain still works and can be renewed. From day 30 to day 90 it doesn't resolve but can still be renewed. From day 90 to day 95 it is pending deletion and can't be renewed. It drops 95 days after expiry, at a time Nominet publishes in a daily drop list. Nominet released this process on 13 September 2022 (Nominet expiry process).

Moving a domain to another registrar doesn't create a new registry record. RDAP logs that as a separate transfer event instead. So an old registration date usually means the name has been renewed without a break. Even so, it doesn't prove the same person has owned it the whole time.

Does domain age help in Google?

Google's John Mueller was asked this on Twitter (now X) in July 2019. His reply was: "No, domain age helps nothing." The post has since been deleted, but an archived copy is still on the Wayback Machine. It's a direct answer from a Google employee, and this guide doesn't claim anything beyond it.

Google's spam policies do cover old domains bought for their history. 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". Google's examples include affiliate content on a site previously used by a government agency (Google spam policies, page last updated 28 August 2026).

Buying an "aged" domain: things to check

• Check whether it dropped. If the registration date is recent but archive captures go back years, the old registration has gone and the name was re-registered.
• Look at what was there before. Browse the archive calendar (web.archive.org/*/example.com) for spam, adult or unrelated content.
• Verify it in Search Console after buying. Check the Manual actions report. Google's advice for someone who has just bought a site that broke its spam policies is to fix the issues, then say in a reconsideration request that the site was recently acquired (Manual actions report).
• Don't pay extra for age alone. Going by Google's statement above, age itself doesn't help.

How to check a domain's age yourself

1. Run the domain through the Domain Statistics lookup. Note the registration date in the Registration panel.
2. Compare it with the first capture date in the report's Archive history panel. A big gap the wrong way round (old captures, recent registration) suggests a drop and re-registration.
3. Open the Wayback Machine calendar to see what the site looked like over time. Our Wayback Machine guide explains how to read it.
4. If you're comfortable with raw data, query RDAP directly. For a .uk name, the pattern is https://rdap.nominet.uk/uk/domain/example.co.uk. Other TLDs' servers are listed in the IANA bootstrap file.
