Domain Age Checker

The Domain Age Checker tells you how old a domain is by looking up its registration date via RDAP/WHOIS, then calculating the number of days, months and years since that date. Domain age is one of the oldest and most durable trust signals in the SEO and cybersecurity world — a well-established domain (10+ years old, consistently renewed, no drops) is treated very differently by search engines, spam filters and browser reputation systems than a domain registered last week.

SEOs check domain age when buying an expiring domain, evaluating an acquisition target, auditing a competitor's link profile, or explaining ranking gaps between two similar sites. Security teams use age as one input to fraud detection — most phishing domains are days or weeks old, so a newly registered lookalike domain is a strong red flag. Brand-protection teams monitor freshly registered domains that resemble their brand to catch typosquatters and impersonators early.

Domain age is not the same as brand age or content age. A domain can be old but sitting empty, or freshly registered but backed by a well-established brand's older domain. Use domain age alongside a WHOIS lookup, archive.org history and backlink data for a full picture.
