Assessing a domain's technical health means checking several things at once: whether DNS is configured correctly, whether the SSL certificate is valid, whether on-page SEO has basic flaws, whether email is protected against spoofing, whether there are unnecessary redirects, and what technology is behind it. Doing it tool by tool works, but when what you need is a quick overall snapshot (for example, before taking on a new client's project, or reviewing your own site after months of not touching it), a single report saves time.
What this audit combines
- DNS: A, MX, TXT, NS and other records, to confirm the domain resolves correctly.
- WHOIS: registrar, registration and expiry dates of the domain.
- SSL: certificate validity, TLS protocol and security grade.
- SEO: basic on-page checks (title, meta, H1, schema).
- Email: whether SPF, DKIM and DMARC are correctly configured.
- Redirects: whether there are long or unnecessary chains on the main URL.
- Tech stack: what framework, CMS, CDN and analytics the site uses.
Everything is summarized in a score from 0 to 100, with each category's detail available to dig deeper where needed.
How to run the audit
- Enter the domain you want to analyze.
- The tool runs all checks in parallel.
- Review the overall score and the per-category breakdown.
You can do it free with the web analyzer on this site.
When the full report makes sense vs. an individual tool
If you need to dig into one specific aspect (for example, debugging exactly why email isn't arriving, or seeing the full detail of a redirect chain), the individual tools give more control and detail: DNS Lookup, WHOIS Lookup, SSL Checker, SEO analyzer, email security, redirect checker and tech stack detector.
The web analyzer makes more sense as a first look: when you don't yet know where the problem might be, or you simply want an overall score to compare several domains' status.
Real use cases
- Before taking on a website maintenance project: understanding in minutes the site's real technical state, beyond what the client tells you.
- Periodic audit of your own site: a quick quarterly review catches certificates about to expire, email configurations that stopped working, or SEO issues that slipped in unnoticed.
- Comparing several domains: when evaluating providers, competitors or candidates for a domain purchase, having a comparable score for each speeds up the decision.
Frequently asked questions
Do I need access to the domain to audit it? No, all checks are based on public information (DNS, WHOIS, SSL certificate, the page's HTML).
How long does the full audit take? Seconds; all checks run in parallel.
Is the score comparable between different domains? Yes, the methodology is the same for any domain analyzed, so it's useful for comparing several sites' relative status.
Does it replace the individual tools? For a first diagnosis, yes; to dig into a specific issue, the individual tools offer more detail and configuration options.
