Crawlsonar

Full Domain Audit

One input, one report. We run every check — DNS & email, SSL/TLS, HTTP security headers, robots.txt, sitemap, llms.txt and AI readiness — in parallel and aggregate them into a single scored report with prioritised fixes.

What’s included

The audit combines all of our individual tools, each weighted by impact:

  • AI Readiness — how LLMs and AI agents read the page (content extraction, structured data, crawler policy).
  • HTTP & security headers — HTTPS, HSTS, CSP, redirects, cookie flags.
  • SSL / TLS — certificate validity, expiry, chain and protocol.
  • DNS & email — records plus SPF and DMARC authentication.
  • robots.txt, sitemap & llms.txt — crawlability and AI/SEO discoverability.

Each module card links to the dedicated tool for the full detail behind its score. Modules that can’t run (for example TLS on an HTTP-only host) are shown but excluded from the overall score, so one failure never sinks the whole report.

FAQ

How long does it take?

Usually a few seconds — every module runs in parallel with its own timeout.

How is the overall score calculated?

It’s an impact-weighted average of the module scores that ran successfully — fully explainable, never a black box.

Frequently asked questions

Is the domain audit free?

Yes — every check runs for free with no account. It aggregates DNS, SSL/TLS, HTTP security headers, robots.txt, sitemap, llms.txt and AI readiness into one scored report.

What does the overall score mean?

It's an impact-weighted average of each module's score, capped by the most severe issue found, so a critical problem can't hide behind otherwise-green results.

Do you store the sites I scan?

Scans run on demand and aren't stored unless you explicitly create a shareable report. We report only on public data from the target you enter.
