How old is any website?
Enter a domain to see exactly when it was registered, who the registrar is, and where it ranks on the Tranco top-100k popularity list.

Domain age is the time between a domain's first registration and today. It's often used as a proxy for trust: an aged domain with a clean history typically has more accumulated backlinks, more brand mentions, and more time to earn editorial links than a newly-registered one. That said, age alone doesn't rank a site — Google has confirmed it's a weak signal at best, and a 20-year-old site with no links won't outrank a 6-month-old site with 500 quality links.
We pull registration data live from RDAP (the modern replacement for WHOIS) and cache it for 30 days. Where available, we also include the registrar and the domain's Tranco popularity rank — refreshed weekly from the Tranco research list.
How it works
Submit a domain and we query the appropriate registry's RDAP server (different TLDs have different endpoints — .com goes to Verisign, .dev to Google Registry, etc.). We extract the original registration timestamp, calculate the age in years and months, and return it alongside the registrar.
Anonymous users get 5 free checks per day. Sign up free for 25/day. The data also ships in every /v1/domain-authority response on our REST API.
Frequently asked questions
- Does domain age affect SEO?
- Marginally. Google's John Mueller has said domain age is not a meaningful ranking factor in itself. What correlates with ranking is what an aged domain tends to have: more backlinks, more historical content, more brand recognition. A new domain with strong content and links can outrank an old domain with neither.
- What's the difference between RDAP and WHOIS?
- RDAP is the modern, structured, JSON-based replacement for WHOIS. Most TLDs now serve registration data primarily via RDAP. We use RDAP because the responses are reliable, parseable, and don't require scraping unstructured text.
- Why is the registrar missing for some domains?
- Some registries (especially ccTLDs) don't expose the registrar in public RDAP, or redact it for privacy. The registration date is almost always available even when the registrar is not.
- Can I check expired or for-sale domains?
- Yes — RDAP returns the original registration date even for expired or auction domains, as long as the domain is still in the registry.
- Is this real WHOIS data?
- Yes — RDAP is the official, registry-served data. It's the same source the major WHOIS lookup tools use, served live.
