🛡️ Domain Trust Signals

Most "authority checker" tools online show you a single made-up number and call it Domain Authority or Trust Flow. Those are real metrics — but they belong to Moz and Majestic, are built from enormous proprietary link databases, and can only be queried through a paid API. Any free tool showing you a DA score is either scraping Moz's site (against their terms, and often wrong) or generating a number from thin air. This tool takes a different approach: instead of guessing at a fake score, it checks several things that actually correlate with a trustworthy domain — how old it is, whether its SSL certificate is valid, whether basic security headers are configured, and whether it publishes a robots.txt and sitemap. None of this replaces a full backlink audit, but all of it is real and verifiable.

How to Use This Tool

Enter a domain name (no need for "https://" — just the domain, like example.com) and click Check Trust Signals. The tool queries the domain live: it looks up WHOIS registration data for its age, opens an SSL connection to inspect the certificate, fetches the homepage to check security headers, and checks for a robots.txt and sitemap.xml at their default locations.

What This Tool Checks

Domain age (from public WHOIS records), SSL certificate validity and expiry, presence of common security headers (Strict-Transport-Security, X-Content-Type-Options, X-Frame-Options, Content-Security-Policy), whether the site redirects HTTP to HTTPS, and whether robots.txt and sitemap.xml exist at their standard paths.

Understanding Your Results

A green checkmark on every signal is a good sign but not a ranking guarantee — these are baseline technical-trust indicators, not a replacement for real backlink or content analysis. A very new domain (under six months) isn't automatically untrustworthy, but combined with a missing SSL certificate or no security headers, it can be a red flag if you're vetting a site before buying a link placement on it.

How to Fix Common Problems

If your own domain shows warnings: renew or install an SSL certificate through your host or a free provider like Let's Encrypt; add HTTP→HTTPS redirects in your .htaccess or server config; add security headers via your web server config or a plugin; and make sure a sitemap.xml is generated (most SEO plugins do this automatically) and referenced in your robots.txt.

SEO Best Practices

Use this tool as a first-pass filter when someone offers you a guest post or link placement on a domain you don't recognize — a domain that fails several of these basic checks deserves a closer look before you pay for a placement there. Pair it with an actual visit to the site: does it look like a real, maintained website with real content, or a thin placeholder?

Example

Checking "wikipedia.org" returns: domain age well over two decades, valid SSL with months remaining, all four security headers present, automatic HTTPS redirect, and both robots.txt and sitemap.xml found — a clean sweep, as expected from a major, actively maintained site.

Common Mistakes to Avoid

Don't treat this as a substitute for a real backlink profile check — it says nothing about the quality or quantity of links pointing at the domain. Don't reject a domain purely for being new; plenty of legitimate new businesses have brand-new domains. And don't confuse "passes trust signals" with "will pass link juice" — those are different questions entirely.
