How we calculate the Domain Age Checker
What it measures
A domain's registration date, sourced from public WHOIS/RDAP records.
How it works
- 1The tool queries the domain's public RDAP (or WHOIS, where RDAP isn't available) record directly.
- 2The registration date returned is the real, current public record — not an estimate.
Real limitations
- Some registrars redact or delay WHOIS/RDAP data for privacy, which can make a domain's true age unavailable or approximate.
- Domain age itself is a weak, indirect signal — it correlates loosely with trust but isn't a direct ranking factor.
