What Is Domain Age?
Domain age is the length of time since a domain name was first registered. It is counted from the official "registration" event in the domain's RDAP record — the same record registrars are required to publish. A domain registered on 15 March 2010 is, as of late 2026, more than sixteen years old.
Note that domain age is not the same as website age. A domain can be registered for a decade while hosting an active website for only two years — or no website at all. RDAP tells you when the name was claimed, not what has been built on it. Both facts matter, but they answer different questions.
Why Does Domain Age Matter for SEO?
Let's be straight: Google has repeatedly said that domain age by itself is a minor ranking signal. An old domain with thin content will not outrank a new domain with genuinely better content.
So why does every serious SEO still check it? Because age correlates with the things that do move rankings. An older domain has had more time to earn backlinks, attract brand searches, and accumulate topical authority. When you're buying an expired domain, a twelve-year-old name with a clean history gives you a head start a fresh registration simply cannot match. When you're prospecting backlinks, a ten-year-old referring domain is usually a safer bet than one registered last month. Age doesn't guarantee quality — but all else being equal, it tilts the odds.
How to Check Domain Age in Bulk
- Paste your list — one domain per line or comma-separated. The tool accepts up to 500 domains and removes duplicates automatically.
- Click "Check Age" — lookups run in parallel batches with a live progress bar, so a full 500-domain list typically finishes in a few minutes.
- Review the table — registration date, exact age, and registrar appear row by row as results stream in.
- Export CSV — download the full report for your spreadsheet or client deliverable.
Understanding Your Results
Registered — the domain is taken. You'll see its creation date, age in years and days, and the registrar of record.
Available — the domain is not currently registered. If you're hunting expired or brandable names, these are your opportunities.
Not available — the registry didn't return public age data. This happens with some country-code domains (for example, .pk has no public RDAP), registries that redact creation dates, or temporary lookup failures. It does not necessarily mean the domain is unregistered.
Frequently Asked Questions
Is this tool really free?
Yes — unlimited checks, no account, no API key. The data comes from public RDAP records, which cost nothing to query.
Where does the data come from?
From RDAP (Registration Data Access Protocol), the official replacement for WHOIS. Every accredited registrar publishes RDAP records, and our server queries the correct registry for each TLD automatically.
Why do some domains show "not available"?
Three common reasons: the TLD's registry doesn't publish public creation dates (several ccTLDs, including .pk), the registry redacts the data for privacy, or the lookup timed out. Retrying once often resolves temporary failures.
Does an older domain automatically rank better?
No. Age is a trust correlate, not a ranking guarantee. A two-year-old domain with strong content and real backlinks will beat a fifteen-year-old parked domain every time. Use age as one input among many.
How long does a 500-domain bulk check take?
Typically two to four minutes, depending on how quickly each TLD's registry responds. Results stream in live, so you don't wait for the whole batch to see the first rows.
Can I see who owns a domain?
No — this tool shows registration date and registrar only. Ownership details are redacted in most public records under current privacy rules.
A Note on Accuracy
RDAP is the most authoritative public source for registration dates — it comes straight from the registries. That said, no bulk tool is perfect: registries occasionally return stale data, and privacy-redacted records can't be resolved from outside. For high-stakes decisions like a four-figure domain purchase, confirm the creation date with a second source before committing.
