Why domain age matters for SEO + trust

Older domains rank better, full stop. Google factors domain age into ranking trust signals — a 15-year-old site has 15 years of backlink history and abuse-resistance that no new domain can fake. Displaying 'Online since 2008' on your own site is one of the cheapest, highest-trust signals available.

Free WHOIS domain age lookup

Paste any domain and instantly see its WHOIS-verified registration date, calculated age in years, expiry date, and registrar. We hit the same authoritative WHOIS database that GoDaddy, ICANN and Namecheap use — the real source of truth, not a scraped guess.

Display your established date as a customer-facing badge

Trust is one of the hardest things to manufacture online. A small 'Since 2014 · FeedPulse Verified' badge on your homepage, About page, or footer is a passive trust signal that compounds over time — especially powerful for ecommerce, financial services, and indie SaaS.

Works everywhere — WordPress, Shopify, Wix & more

Copy the HTML snippet, paste it once, never think about it again. The badge auto-updates the age display each year on your domain's anniversary.

Frequently asked questions

Questions we hear most often — also emitted as FAQPage schema so search engines can surface these in “People also ask” results.

+How is domain age calculated?

Domain age is the number of years (with fractional months) between today and the WHOIS-verified original registration date of the domain. We hit the authoritative WHOIS database that registrars like GoDaddy, Namecheap, and ICANN use — the real source of truth, not a scraped guess.

+Does domain age affect SEO?

Yes. Google factors domain age into ranking trust signals because older domains have years of backlink history and abuse-resistance that new domains can't fake. The boost is small per-year, but compounding — a 10-year domain has measurably more ranking inertia than a 1-year-old competitor with otherwise identical SEO.

+How can I check the age of any website?

Paste the domain above — we'll instantly show its WHOIS registration date, calculated age in years and months, expiry date, and current registrar. Works for any TLD that supports WHOIS / RDAP (essentially all of them: .com, .net, .org, .io, .ai, country-code TLDs, etc.).

+Is the WHOIS data accurate?

Yes — we read directly from ICANN's authoritative WHOIS / RDAP feeds, the same source registrars query. Note that some new TLDs (.app, .dev) and some EU domains hide registrant details under GDPR — but the registration DATE is always public for SEO purposes.

+Can I display 'Online since 2008' on my site?

Absolutely — that's exactly what the embeddable Domain Age badge does. After checking your domain above, customize the badge in the right panel, copy the HTML snippet, and paste it on your homepage, About page, or footer. The badge auto-updates the age display on every anniversary.
