data.iana.org, which never receives your domain), then asks the registry’s RDAP server for that one domain, for example rdap.verisign.com for .com. With “Also ask the registrar” on, it also asks the registrar’s RDAP server the registry points to. Only the domain name is sent. TapCub’s servers are not involved and store nothing.Up to 20, one per line or separated by commas.

Version v1.0Updated Update history
What the age means
Age is counted from the registration date the registry holds.
Age
Years and months since the current registration began, in UTC calendar days. Hover the age for the exact number of days.
Registration resets
If a domain expired, was deleted and registered again, the date starts over. An old-looking site can have a young date, and the reverse.
Transfers do not reset
Moving to another registrar or changing owner keeps the original registration date in most registries.
Young domains
Less than six months is flagged. That is useful context for a referrer or a seller, not proof of anything.
Some registries, such as .cn and .io, do not offer RDAP to browsers. Those domains show “not in RDAP”; check them on the registry’s own site.
Three steps
No sign-up, no CAPTCHA.
-
1
Enter the domain
Type it or paste any URL from the site.
-
2
Look up
The tool finds the right registry from IANA’s list and asks it directly, then the registrar if you leave that ticked.

Domain age and Google Search
What Google has published, checked on 2026-11-11, and nothing more.
- Google’s guide to its ranking systems lists 17 systems in use. None is about domain age; its “freshness” systems are about how recent the content is
- Google’s spam policies name expired domain abuse: an expired domain “purchased and repurposed primarily to manipulate search rankings” with little value to users
- So buying an old domain for its age is not a ranking shortcut Google documents, and repurposing one to game rankings is explicitly against its policies
| Registered | Checked | Age |
|---|---|---|
| 2007-10-09 | 2026-11-11 | 19 years, 1 month (6,973 days) |
| 2026-09-29 | 2026-11-11 | 1 month, 13 days (43 days) |

Domain age mistakes
A few conclusions the data does not support.
Buying age for rankings
Google does not list domain age among its ranking systems, and repurposing an expired domain to manipulate rankings is a named spam policy.
Trusting a site because it is old
An old date only says the registration has been renewed. The domain may have changed owners several times.
Comparing Wayback snapshots with age
Archived pages show when a site was crawled, not when the domain was registered. Use both, for different questions.
Where an unknown domain shows up
Domains turn up in analytics as referrers and in bot reports as crawler operators. A quick registration check helps decide what to make of them.
Referring domains
Sources lists every site that sends visitors. A referrer registered last week with hidden details deserves a closer look before you count it as a channel.
Learn moreBots on a separate line
TapCub keeps crawlers out of human reports. Look up the operator behind an unfamiliar crawler’s domain.
Learn moreOne snippet
Analytics and live chat share the same snippet, so a new site you own needs one install.

How do I check how old a domain is?
Enter it above and click Look up. The age is counted from the registration date in the registry’s RDAP record, the same date a WHOIS lookup shows as “created”.
Does domain age affect SEO?
Google’s published guide to its ranking systems does not include domain age; its freshness systems are about content. Google’s spam policies do name expired domain abuse, repurposing an expired domain to manipulate rankings.
Why does an old site show a recent registration date?
The domain probably expired and was registered again, which starts a new registration. Changing registrar or owner usually keeps the original date.
Can I check .cn or .io domains?
Not here: those registries are not in IANA’s RDAP list, so browsers cannot query them. Use CNNIC’s WHOIS page for .cn, or the registry listed on IANA’s page for the ending.
