Domain age checker: how old is a domain?

Domain age comes up in almost every SEO conversation I have with a new client, usually as a worry: "our domain is only two years old, is that why we don't rank?" The honest answer is no. Google has said plainly that the registration date isn't something it rewards. John Mueller put it in four words in 2019: domain age "helps nothing".

So why build a domain age checker? Because the date is still useful information, just not as a ranking factor. I look it up for practical reasons: before a client buys a domain that someone else owned, when a competitor seems to appear out of nowhere, when I need to know who the registrar is during a migration, and when I want to make sure a client's own domain isn't about to expire. That last one sounds basic, but a lapsed domain takes the website and the email down with it.

The checker reads the registry's RDAP record, the standard that replaced WHOIS, and adds the earliest snapshot from the Internet Archive. Together they tell you how long the current registration has existed and how long the name has been in use.

Not directly. What an older site usually has is a history: years of pages, links from other sites, brand searches and people who know it. Those things help. The date on the registration is just a side effect of having been around long enough to collect them.

You can see this in any competitive search. New sites outrank old ones when they answer the search better and earn links faster, and old sites lose rankings when they stop being maintained. When I work on SEO for clients, from a telecom company in Saudi Arabia to med spas in the USA, I never treat a young domain as the problem. The work is the same: a site Google can crawl, pages that answer real questions, and reasons for others to link.

One thing domain history can do is hurt. Google's spam policies name expired domain abuse: buying an old domain for its past reputation and filling it with unrelated, low-value content. If you buy a used domain, build something that fits what it was, or accept that its past won't carry over.

Some lookups I ran while building the tool show what the dates tell you. google.com was registered on 15 September 1997 through MarkMonitor, a registrar that large brands use to protect their domains. Its first Wayback Machine copy is from November 1998, about a year later, which is normal: the name was bought, then the site launched and got noticed.

bbc.co.uk returns a record from Nominet, the UK registry, with a creation date of 13 December 1994 and a first archived copy from December 1996. For many .uk domains, the registrar field shows the organisation that holds the tag, so don't be surprised to see a company name there instead of a familiar registrar.

The pattern to watch for is the reverse: an archived copy years older than the registration. It means the name was in use under an earlier registration that lapsed, and the tool adds a note when it sees this. Whoever held it before may have been you, a business that closed or someone running a spam site. Open a few of those old snapshots before you assume the history is clean.

The status codes are worth a glance too. "client transfer prohibited" is a normal lock that stops someone moving the domain without your say-so. "redemption period" or "pending delete" means the domain has expired and is close to being released.

Each domain extension is run by a registry: Verisign for .com and .net, for example. The checker asks rdap.org, which forwards the request to the right registry using the official IANA list. For some extensions, the registry points to the registrar's own RDAP server, which I query too when the registry record is missing a field.

The archive date comes from the Internet Archive's public CDX index, which lists captures oldest first, so the first result is the earliest copy of the site. Nothing you type is stored, and lookups are rate-limited so the service stays fair for everyone.

If you're checking a domain because a site lost traffic, a free SEO audit of its main pages will tell you more than the date. And if the site is a migration that went wrong, that's the kind of problem I fix in technical SEO work.
