Domain age checker for SEO, trust, and due diligence

Look up domain registration date, expiration, and last changed timestamps from public RDAP data. See an estimated domain age in years and months—ideal when you need a fast signal alongside content quality, backlinks, and technical checks.

How to use this domain age lookup

Paste a bare hostname such as example.com or a full https://www.example.com URL—our parser keeps the host, normalizes casing, and applies the same public-network safety checks we use elsewhere. Submit the form to query RDAP; when a subdomain does not have its own registration object, we progressively remove leftmost labels until we reach a likely apex match (for example www. prefixes and deep hosts). Read the registration event as the usual starting point for how old the domain is, then cross-reference expiration with your renewal calendar and last changed with migration or transfer history.

Pair age research with routing data from our DNS lookup tool, transport security from the SSL certificate checker, and HTTP behavior from the HTTP header checker so you are not judging a brand on registration metadata alone.

Domain age and SEO: what practitioners actually measure

SEO discussions often mention domain age as a proxy for stability. Publicly visible registration timestamps can align with long-running brands, but they do not replace on-page quality, crawl health, or authoritative backlinks. Use this utility to capture a reproducible domain created date snapshot, then continue audits with our redirect chain checker, response code checker, and canonical tag checker to verify how search engines experience your URLs in practice.

WHOIS vs RDAP: why we prefer RDAP for age checks

RDAP delivers structured JSON over HTTPS, which scales better for lightweight tools than parsing legacy WHOIS text. When you need a complementary registrar-oriented view, open our WHOIS lookup as well. Registries still control redaction, so some fields may be missing even when domain expiry and registration events are present. If you need live page metadata rather than naming-system records, pivot to the meta tags extractor or technology detector after you finish registrar-level research here.

Frequently asked questions

What is domain age and why does it matter?
Domain age usually means how long a domain name has been continuously registered, often measured from the original registration date in RDAP/WHOIS-style records. Teams reference it for quick trust heuristics, competitive research, and SEO context—alongside content quality, backlinks, and technical health—not as a single ranking guarantee.
How does this domain age checker work?
You enter a hostname (with or without https://). We resolve DNS to ensure the name does not point at non-public networks, then query public RDAP data via rdap.org so registry responses stay consistent across many TLDs. When a subdomain has no separate registration record, we may walk up labels toward the apex (for example www.example.com → example.com) until a match is found.
Is domain age the same as website launch date?
No. Registration date reflects when the domain was created in the DNS namespace; the site could have launched later, changed owners, or sat parked. For live-page signals, combine this check with our HTTP header checker, redirect chain checker, and SSL certificate checker.
Why is my subdomain not found until I use the root domain?
Many registries publish one RDAP object for the registrable apex name. Deep subdomains (blog.shop.example.com) may not have their own registration row, so the tool retries by removing leftmost labels until it reaches a plausible apex. Country-code rules vary; when in doubt, type the exact registrable domain you see at your registrar.
Does older always mean better for SEO?
Search engines emphasize usefulness, relevance, and trust signals—not a domain birthday alone. Age can correlate with longevity and brand history, but thin content, spam, or poor technical SEO can outweigh it. Use domain age as one data point in a broader audit that includes content, Core Web Vitals, and link quality.
What if RDAP shows privacy or missing registrar details?
Registries and registrars redact personal data under GDPR and similar laws, but many responses still include registration and expiry timestamps. If a field is absent, the registry may omit it for that TLD; try again later or cross-check with your registrar dashboard.
Can I look up any TLD?
We rely on public RDAP routing. Most gTLDs and many ccTLDs work, but some registries lag, block automated clients, or require manual portals. If lookup fails, verify spelling, try the apex domain, and confirm the TLD publishes RDAP.
How should I use this alongside WHOIS or DNS tools?
Use this page for fast age and lifecycle timestamps from RDAP, pair with our DNS lookup when you need A/AAAA/MX/TXT answers, and use registrar consoles for billing contacts. Together they cover naming, routing, and registration metadata without confusing one layer for another.
