Domain Age Checker

Open a free domain age checker, type the root domain (without http or www), and hit check. The tool pulls RDAP data and shows you the creation date, last updated date, expiry, and the calculated age in years and days. I usually tell my juniors to copy these details into the audit sheet straight away. For competitor research or buying a dropped name, this is your starting point — never the only one. Cross-check against Wayback Machine before you trust it.

RDAP returns an "events " array, and inside that you'll find a "registration " event with a date stamp. Domain age is simply today's date minus that registration date — that's it, no magic. We display it in years, months, and days because clients prefer readable numbers over raw timestamps. One thing to remember: if the domain was deleted and re-registered later, the registration event resets to the new date. So always check WHOIS history if the age looks suspicious for a known old brand.

A few common reasons. Some registries redact event data for privacy, especially for ccTLDs in Europe. Others return an incomplete event array — the registration field may simply not be published. Many ccTLDs like .de or .fr don't expose creation dates over RDAP at all. And sometimes it's just a temporary lookup failure or rate limit. When this happens, fall back to the registrar's WHOIS panel or check the IANA bootstrap to confirm if RDAP is even supported for that TLD.

No, transferring a domain between registrars does not reset its age. The original creation date stays intact in the registry record — only the "last updated " or transfer event changes. So if your client moves a 12-year-old domain from GoDaddy to Namecheap, it's still 12 years old. The only time age genuinely resets is if the domain was allowed to expire, dropped, and then re-registered as a fresh name. That's a different scenario and shows up clearly in WHOIS history tools.

Honestly, it's overrated. Google has said multiple times that domain age by itself is not a direct ranking factor. What actually matters is the quality of content, backlink profile, topical authority, and user signals built up over time. An older domain often performs better simply because it has had more time to earn links and trust — not because of the age number itself. A 6-month-old site with great content and strong links can outrank a 10-year-old neglected one easily.

There's no fixed number — age alone doesn't tell you much. I look at the full picture: backlink history (Ahrefs or Majestic), traffic trend over the last 2–3 years (SimilarWeb), spam score, indexed pages, and previous owner footprint via Wayback Machine. A 4-year-old clean domain with relevant backlinks is far more valuable than a 15-year-old expired one stuffed with casino spam. Run a manual penalty check too — sometimes "great age " hides a Google penalty waiting to surface.

Domain age is when the name was first registered — that's a registry record. Website age is when actual content first went live on it. The two often don't match. I've seen 20-year-old domains that were just parked for 18 years and only became real websites in 2022. To check website age properly, use Wayback Machine and find the earliest meaningful snapshot. For client pitches, I always present both numbers separately so nobody misreads "old domain " as "old brand."

Sometimes, sometimes not. It depends entirely on whether that ccTLD registry supports RDAP and publishes event fields. .in domains generally work because INRegistry publishes RDAP data. But .de, .nl, and several others either don't expose creation dates or restrict access entirely. If your tool returns blank for a ccTLD, check IANA's RDAP bootstrap file to see if RDAP is even listed — if not, the registrar's account dashboard or the registry's own WHOIS page becomes your only option.

Different sources, different update timing. WHOIS is older, less standardized, and often cached at the registrar level. RDAP is structured JSON, pulled fresh from the registry, and has cleaner field definitions. WHOIS may also redact more fields under privacy policies, while RDAP follows specific access rules. Slight date mismatches usually come down to caching delays or how each format handles the "registration " versus "created " field. When in doubt, RDAP is the more reliable modern source — but always note the discrepancy in your audit.

Start with RDAP — pull the registration event date. Then cross-check with the registrar's account records if you have access. For deeper verification, run the domain through Wayback Machine to see the earliest archived page, and check DomainTools' WHOIS history (paid but worth it for legal or acquisition cases). If three sources agree, you're solid. If they disagree, the registry's own RDAP endpoint is the authoritative answer because that's the source of truth — registrars and aggregators are downstream copies.
