Domain Age Checker
Check when any domain was registered (official registry data) and when it first hosted a real website (Internet Archive) — the two dates that matter for due diligence.
Quick answer
What is domain age?
Domain age is the time since a domain name was first registered. This tool reports two verifiable dates for any domain: the official registration date from the registry's public RDAP record, and the first time the Wayback Machine ever archived the site — which shows how long the domain has actually hosted content, not just been parked.
Does domain age matter for SEO?
Google has said age itself is not a meaningful ranking factor — but the things that accumulate with age are: backlinks, content depth, brand queries, and trust history. That's why the registration-vs-first-archive gap in this tool is often more interesting than the age number: a domain registered in 2010 but first archived in 2023 spent 13 years parked and carries little of the equity its age implies.
Age checks are essential due diligence when buying expired domains or evaluating competitors: a long, continuously-archived history with consistent topic focus is a genuinely strong asset; a long registration with gaps, redirects, or topic flips can hide a spam history.
How to use the two dates
- Registration date (RDAP) — the domain's legal birthday, straight from the registry.
- First Wayback snapshot — the earliest evidence of a live site; browse the archive around that date to see what the domain used to host.
- Big gap between the two — the domain was parked or private; discount its effective age.
- Expiry date — when evaluating a domain purchase, confirm the current registration isn't about to lapse.
Where this data comes from
Registration, expiry, and registrar come from RDAP — the registries' official, structured successor to WHOIS — queried live per lookup. First-archive dates come from the Internet Archive's public CDX API. Both are primary sources; results are cached for up to 30 days. Some country-code TLDs don't publish registration dates via RDAP, in which case the first Wayback snapshot is shown as the best verifiable evidence of age.
Frequently asked questions
Is domain age a Google ranking factor?
Not directly — Google representatives have repeatedly said age itself carries little to no weight. What matters is what accumulates over time on an active domain: backlinks, content, and brand recognition. A 15-year-old parked domain has age but none of that equity; a 3-year-old actively-grown site can outrank it comfortably.
Why do the registration date and first-archive date differ?
Registration is when someone first bought the name; the first Wayback snapshot is the earliest evidence of a live website. A large gap usually means the domain sat parked. For SEO due diligence, the archive history is often the more honest measure of a domain's working age.
How do I check what a domain used to look like?
Take the first-snapshot date from this tool and browse web.archive.org for the domain around that time. When evaluating an expired domain purchase, review several snapshots across its history — topic changes, redirect periods, or spam phases are the red flags that kill a domain's value.
Why is no registration date shown for some domains?
Some registries — notably several country-code TLDs — don't expose registration dates through public RDAP. When that happens we still show the first Wayback capture, which sets a verifiable lower bound on the domain's age.
Does buying an old domain boost a new site?
Only if the domain has genuine, topically-relevant link equity and a clean history — and you continue its topic rather than flipping it. Redirecting an old domain about gardening to a crypto site passes little value and can attract scrutiny. Verify history with the archive before paying an age premium.
Is this data live or cached?
Lookups hit RDAP and the Wayback CDX API live, then cache for up to 30 days — registration dates don't change, so caching keeps the tool fast without staleness risk. The expiry date is the one field worth re-checking before a purchase decision.
