Analyze domain strength based on DNS, age, and infrastructure signals.
Enter a domain above to check its authority score
Powered by Google Public DNS and RDAP. Scores are based on publicly available infrastructure signals.
Domain authority is a measure of how well-established and trustworthy a domain is based on its infrastructure, history, and configuration. While traditional domain authority metrics from SEO platforms rely on backlink data, this tool takes a different approach by analyzing publicly available signals that anyone can verify.
The score considers six key factors: domain age, DNS record completeness, email infrastructure, email authentication protocols (SPF, DKIM, DMARC), nameserver quality, and HTTPS configuration. Each factor contributes to a composite score from 0 to 100 that reflects the domain's overall technical maturity.
The authority score is a weighted composite of six categories. Domain age contributes up to 25 points, with older domains receiving higher scores since longevity signals stability and trust. DNS completeness awards up to 20 points for having A, MX, NS, and TXT records properly configured.
Email infrastructure (up to 15 points) evaluates whether the domain has professional email routing with multiple MX records. Email authentication (up to 15 points) checks for SPF, DKIM, and DMARC records that prevent spoofing. Nameserver quality (up to 15 points) rewards domains using reputable DNS providers with redundant nameservers. Finally, HTTPS configuration (up to 10 points) confirms the domain supports secure connections.
Search engines use hundreds of ranking signals, and several of them overlap with the factors this tool measures. Domain age is a well-known trust signal. Proper DNS configuration ensures your site is reliably accessible to search engine crawlers. HTTPS is a confirmed Google ranking factor.
Email authentication matters because domains that send authenticated emails build sender reputation, which correlates with overall domain trust. Professional nameserver infrastructure reduces downtime and improves resolution speed, both of which affect crawlability and user experience.
Start with the basics: ensure your domain has A records pointing to your server, MX records for email, and at least two nameservers from a reputable provider. Add SPF, DKIM, and DMARC records to authenticate your emails and prevent spoofing.
Enable HTTPS with a valid SSL certificate if you have not already. Consider migrating to a premium DNS provider like Cloudflare, AWS Route 53, or Google Cloud DNS for better performance and reliability. While you cannot change your domain's age, maintaining consistent ownership and activity builds trust over time.
This tool analyzes six infrastructure signals: domain age from RDAP records, DNS record completeness (A, MX, NS, TXT), email infrastructure quality, email authentication (SPF, DKIM, DMARC), nameserver quality and redundancy, and HTTPS support. It combines these into a composite score from 0 to 100.
Moz Domain Authority is based primarily on backlink profiles and link equity. This tool focuses on infrastructure and technical signals that are publicly verifiable through DNS queries and RDAP lookups. Both approaches provide useful but different perspectives on domain strength.
The score reflects infrastructure signals only. A well-known website might score lower if it lacks DMARC records, uses a single nameserver, or has a relatively young domain registration. The breakdown table shows exactly which categories contributed fewer points so you can identify specific areas for improvement.
Yes, you can check any registered domain. The tool queries public DNS records and RDAP data, so no special access is needed. Some newer or very small domains may have limited RDAP data available, which can affect the domain age portion of the score.
Yes, this tool is completely free. It uses Google Public DNS and public RDAP services to gather domain data. There are no hidden costs or premium tiers for this particular tool.
