Domain Age Checker - SERP

Click the extension to scan Google results and list young domains with their ranking position.

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 FEATURES 🔍 One-click WHOIS/RDAP scan of any live Google search results page 🎚️ Custom age threshold, or quick presets for under 6 months / 1 year / 2 years 📅Registration date and exact SERP ranking position for every flagged domain 🔀 Sort by position or by age 🚫 Ignore list to permanently exclude known domains from future scans 📤 Export findings as CSV or JSON, or copy a plain-text summary 🌓 Light and dark theme, auto-matched to your system ⚡ Results cached for 6 hours for fast repeat scans 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. Install free and scan your first SERP in one click.
