Domain Age Checker - SERP

About

Domain Age Checker - SERP
Domain Age Checker instantly reveals the WHOIS/RDAP registration date of every domain ranking in your Google search results. No API key, no sign-up, no scan limits.

WHAT IT DOES
Click "Scan" on any Google search results page, and the extension pulls each ranking domain's registration date directly from RDAP (Registration Data Access Protocol), the modern, standardized successor to WHOIS. It then highlights every result younger than an age threshold you choose, from under 6 months to under 20 years, and shows exactly where that domain sits in the SERP.

WHY DOMAIN AGE MATTERS
Domain age isn't a confirmed Google ranking factor, but it's one of the most widely used research signals in SEO. Analysts run a WHOIS or RDAP check to spot:
🆕 Newly registered domains (NRDs) breaking into competitive rankings unusually fast
🕸️ Possible private blog networks (PBNs) or expired-domain reuse
📈 Emerging competitors worth tracking before they scale
⚖️ Aged domains vs. fresh domains within the same SERP for competitive gap analysis

WHO IT'S FOR
SEO analysts, content marketers, affiliate site owners, link builders, and researchers who audit SERPs, evaluate competitor domains, or want a faster alternative to manually running a WHOIS or RDAP lookup on every ranking URL.

PRIVACY
Domain lookups go directly from your browser to public RDAP registries (rdap.org, Verisign, who-dat). Nothing is sent to a server we operate. No account required. No personal browsing data is collected.
