Analyze any domain's SEO health in one shot -- authority score, DNS records, SSL certificate, WHOIS data, HTTP response details, technology stack detection, and HTML meta tags. We built this to give you a complete domain profile without needing five different tools.

What does SEO Domain Authority Checker do?

This actor takes a domain name and runs a full technical SEO audit against it. You can check a single domain or submit up to 50 domains in bulk.

For each domain, it performs multiple checks. It calculates an authority score (0-100) based on domain age, DNS configuration, SSL status, and web presence signals. It resolves all DNS records -- A, AAAA, MX, NS, TXT, CNAME, and SOA. It checks the SSL certificate for validity, issuer, expiration date, and TLS protocol version. It pulls WHOIS data including registrar, creation date, expiration date, name servers, and domain age in days.

On the HTTP side, it makes a request and captures the status code, response time in milliseconds, server header, content type, the full redirect chain, and all response headers. It also detects the technology stack -- CMS (WordPress, Shopify, etc.), web framework, analytics tools, CDN provider, and hosting provider. Finally, it extracts HTML meta tags like title, description, and Open Graph data.

The bulk mode lets you submit an array of up to 50 domains and get all results back in one run. Perfect for comparing competitors or auditing a list of prospects.

What data do you get?

• Domain name and authority score (0-100)
• Reachability status (whether the domain responds)
• DNS records: A (IPv4), AAAA (IPv6), MX, NS, TXT, CNAME, SOA
• SSL certificate: validity, issuer, expiration date, TLS protocol version
• WHOIS data: registrar, creation date, expiration date, last updated, name servers, domain age in days
• HTTP info: status code, response time (ms), server header, content type, redirect chain, all headers
• Technology stack: CMS, framework, analytics tools, CDN, hosting provider
• HTML meta tags (title, description, etc.)

Who is this for?

• SEO professionals running quick domain audits and competitor analysis
• Domain investors evaluating domain age, authority, and technical setup before buying
• Sales teams qualifying leads by checking their web presence and tech stack
• Agencies onboarding new clients with a baseline technical SEO report
• Developers checking DNS configuration, SSL status, and server setup

How much does it cost?

This actor costs $0.003 per result (per domain checked). 1,000 domains cost $3, and a bulk check of 50 domains costs $0.15.

Every Apify account comes with $5 in free monthly credits, giving you over 1,600 free domain checks.

Common questions

What does the authority score measure? It is a composite score (0-100) based on domain age, DNS configuration quality, SSL validity, HTTP response, and overall web presence. It is not the same as Moz DA or Ahrefs DR, but it gives you a quick quality indicator without needing a paid SEO tool subscription.

Can I check subdomains? Yes. Enter the full subdomain (e.g., "blog.example.com") and it will be analyzed independently.

How many domains can I check at once? Up to 50 per run using the bulk domains input. For larger lists, run multiple batches or use the Apify API to automate sequential runs.
