5 DNS Checks Every Website Owner Should Run
Your website might look fine on the surface, but hidden DNS issues could be hurting your SEO, security, and email delivery. Here are 5 checks you should run regularly.
1. DNS Lookup — Are Your Records Correct?
Wrong A, CNAME, or NS records can take your site offline. Run a https://dnsrobot.net/dns-lookup to verify all your records resolve correctly from multiple global locations.
2. SSL Certificate — Is It Valid and Not Expiring?
An expired or misconfigured SSL breaks trust and tanks your Google rankings. Use an https://dnsrobot.net/ssl-checker to see your certificate chain, expiry date, and protocol support.
3. WHOIS — Is Your Domain Info Up to Date?
Outdated WHOIS data can cause renewal failures and transfer issues. A quick https://dnsrobot.net/whois-lookup shows your registrar, expiry date, and nameserver configuration.
4. SPF, DKIM & DMARC — Can You Actually Send Email?
If these DNS records are missing or broken, your emails go straight to spam. Check all three at once with the https://dnsrobot.net/spf-checker, https://dnsrobot.net/dkim-checker, and https://dnsrobot.net/dmarc-checker.
5. Domain Health — The Full Picture
Instead of checking things one by one, run a complete https://dnsrobot.net/domain-health to get DNS, SSL, email authentication, and security headers in one report.
