How to check domain authority in 3 easy steps

1. Go to the Domain Authority Checker page on Apify and click "Try for free".
2. Configure your input — enter a list of domains (or upload a CSV), set concurrency and timeout, and choose which checks to include (SSL, DNS, meta tags, tech detection).
3. Click "Run", wait for the results, and download your SEO report in JSON, CSV, or Excel format.

No coding required. Works with Apify's free plan.

What it does

For each domain, the Actor checks:

• Domain Score (0-100) — proprietary score based on all collected metrics
• HTTP Status — reachability and response codes
• Page Load Time — response time in milliseconds
• SSL Certificate — validity, issuer, expiration date
• DNS Records — A, AAAA, MX, NS, TXT, CNAME
• Domain Age — registration date via WHOIS
• Meta Tags — title, description, Open Graph tags
• Technology Detection — server software, frameworks, CDN
• Robots.txt — existence check
• Sitemap.xml — existence and URL count
• Social Links — social media profiles found on homepage
