Domain age checker
Enter a domain to see exactly how old its registration is, when a site first appeared on it, and when it expires. Paste a list to check several at once.
Sending outreach from this domain? GEOboom finds the pages AI answers cite and runs the outreach to get you mentioned on them, with the mailboxes included.
See how it worksWhat a domain's age tells you
Registration
When the current registration began, from the registry's own record. It restarts if the domain lapses and is bought again.
First archived
When a site was first seen on the domain. Earlier than the registration means a previous owner; years later means it sat parked.
Expiry
When the registration runs out. A domain close to expiry with no renewal may not be there next year.
Questions
How is domain age calculated?
From the registration date in the registry's record to today, counted the way a calendar does: whole years, then whole months, then the days left over. A domain registered on October 9, 2007 was 19 years, 1 month and 2 days old on November 11, 2026. We show the dates the figure comes from, so you can check it.
Is the registration date the same as how long a website has existed?
No. It's when the current registration began. A domain that expired and was bought by someone new shows the new date, however long a site had been on it before. A domain can also sit parked for years before anyone builds on it. That's why we show when the Wayback Machine first archived a site on the domain, and point it out when the two dates disagree.
Does domain age affect SEO?
Not directly. Google has said that age by itself isn't a ranking factor. Older domains tend to rank better because they've had time to earn links and content, not because of the date. A new domain with good links can outrank an old one without them.
Why does domain age matter for email and outreach?
Mailbox providers and spam filters treat mail from newly registered domains with more suspicion, because spammers register fresh domains constantly. A domain a few weeks old needs its mailboxes warmed up slowly. When you're judging a link prospect, a very young domain, or one re-registered after expiring, is a sign the site may not last.
Where does the data come from?
From the registry that runs the domain ending, through RDAP, the modern replacement for WHOIS. For endings without RDAP, such as .io and .co, we read the registry's WHOIS record instead. Some registries, such as .de's, publish no dates at all. The first-archived date comes from the Internet Archive's Wayback Machine.
Why does a domain show an age of zero or only a few days?
Either it was registered very recently, or it lapsed and was registered again, which restarts the date. If the Wayback Machine has captures from before the registration date, it's the second: the earlier history belongs to a previous owner.
