Website Health Check & Test
Run a free website health check and test with Web Health. Audit SSL, DNS records, HTTP status codes, security headers, and SPF, DKIM, and DMARC email security in one scan.
Complete Website Health & Performance Audit
Maintaining a healthy website requires continuous monitoring across multiple technical domains. A single security vulnerability or broken DNS record can cause website downtime, email delivery failures, or severe search engine ranking penalties.
The 6 Pillars of Site Health
- 1. SSL/TLS Certificate: Ensures encrypted HTTPS communication and valid certificates.
- 2. DNS Resolution: Verifies A, AAAA, MX, and TXT record routing stability.
- 3. HTTP Response Headers: Checks status codes (200 OK) and server responsiveness.
- 4. Security Headers: Audits HSTS, CSP, and clickjacking protections.
- 5. Email Authentication: Tests SPF, DKIM, and DMARC spoofing defenses.
- 6. WHOIS Registration: Inspects domain expiration deadlines and registrar locks.
Best Practices for Webmasters
- Enforce HTTPS & HSTS: Redirect HTTP traffic to HTTPS and set HSTS header max-age.
- Enforce DMARC Policy: Transition from p=none to p=reject for email protection.
- Monitor Domain Expiry: Enable auto-renewal with your domain registrar.
- Optimize TTL Values: Set appropriate TTLs for quick DNS propagation during changes.
