Free Website Security Checker vs SEOptimer
SEOptimer is strong at quick, presentable on-page audits and embeddable audit forms for lead generation. RankForge covers on-page too, but its differentiator is the structural layer: internal-link recommendations, authority flow, and topic-cluster strength that surface-level audits don't model.
If the job in front of you is website security checker, you can run that check here for free in a couple of minutes with no account. Whether you also need SEOptimer depends on what else you do in a week — which is what the rest of this page is about.
What the free website security checker checks
- SSL/TLS certificate — validity, issuer, and expiry
- Security headers — HSTS, Content-Security-Policy, X-Frame-Options, and more
- Email & domain protection — SPF, DMARC, and DNSSEC records
Where SEOptimer is genuinely better
These are real advantages. If any of them describe your week, SEOptimer is worth paying for and this free check is not a replacement.
- Fast, presentable on-page audit reports
- Embeddable audit forms for agency lead generation
- Simple, approachable for quick client snapshots
