Check your website's security and trust signals.
Is your SSL certificate valid? Are your security headers set? Is your domain protected against email spoofing? RankForge checks your TLS certificate, HTTP security headers, and SPF/DMARC/DNSSEC records — and explains each in plain English. Paste your URL — free, no account required.

What does this tool check?
What problems does this find?
The issues this check most often surfaces on real sites:
- Expired or misconfigured SSL/TLS certificates
- Missing security headers (HSTS, CSP, X-Frame-Options)
- No SPF/DMARC, leaving your domain open to email spoofing
What do I do after the check is complete?
We checked the basics that keep your site safe and trusted: your security certificate, the protective settings your server sends, and the records that stop scammers from faking email from your domain. Here's what's set up and what isn't.
- 1
Start with the pages that matter commercially
Work down the list in order of how much you care about the page, not how bad the number looks. A flagged page nobody needs to find is not worth an hour of your time.
- 2
Fix the cause, not the symptom
Most findings here are structural: a page is unreachable, under-linked, or competing with another page. Adding one contextual link from a strong, relevant page usually fixes more than editing the page itself.

Re-run this check to confirm the fix landed
The check is free and takes a couple of minutes. Re-crawling after a change is the only way to know it worked — and the full audit tracks the difference between crawls for you.
Why website security checker matters for SEO
Security and trust signals protect your visitors and your brand. A valid HTTPS certificate is table stakes — and the one item here that's also a (minor) Google ranking signal. Security headers like HSTS and Content-Security-Policy defend against common attacks, while SPF and DMARC stop scammers from spoofing email from your domain. These aren't SEO ranking factors (beyond HTTPS), but a site that fails them looks untrustworthy to users and is a soft target for attackers — both of which quietly cost you conversions and reputation.
How this compares to paid tools
Honest side-by-sides, including where each paid tool is genuinely the better buy.
Website Security Checker: frequently asked questions
Does website security affect SEO?
Mostly no. HTTPS is a minor Google ranking signal, but security headers (HSTS, CSP) and email-auth records (SPF, DMARC) are not ranking factors. They matter for user trust, safety, and email deliverability — not for where you rank. RankForge keeps them out of its SEO score for exactly that reason.
What are SPF, DMARC, and DNSSEC?
SPF and DMARC are DNS records that stop attackers from sending email that looks like it's from your domain. DNSSEC cryptographically signs your DNS so it can't be tampered with. They protect your domain and your customers, even though they're unrelated to search rankings.
