The domain analyzer tool provides a detailed report on a website's configuration, security, and ownership based on a quick scan.
Enter a domain such as example.com. Reports are public and cached for 14 days.
What is a domain analyzer?
A domain analyzer is a tool that inspects a website and generates a report on its technical setup and security features. When you enter a domain name, the tool contacts the website’s server and gathers data on various aspects of the site. This includes its HTTP status, response time, TLS certificate details, and security headers. The report also covers DNS records, registration information, server location, and more.
What does the domain analyzer check?
The tool performs a comprehensive scan of the domain, covering several key areas:
- HTTP and TLS: It checks the HTTP status code and response time, as well as the TLS certificate, its issuer, expiry date, and the subdomains listed on it.
- Security Headers: It identifies which of six common security headers are set: HSTS, CSP, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, and Permissions-Policy.
- DNS and DMARC: It retrieves DNS records and checks for DMARC, CAA, and DNSSEC configurations.
- Registration Details: It provides registration date, registrar information, expiry date, and registry status from RDAP.
- Server and Hosting: It identifies the server location, hosting provider, and network (ASN) using IP geolocation.
- Website Structure: It analyzes the homepage title, description, word count, headings, and detected platform fingerprints like WordPress or Angular.
- Schema.org Types: It lists the published schema.org types found on the site.
- Robots.txt and Sitemap: It checks robots.txt rules, including whether AI crawlers like GPTBot and ClaudeBot are blocked, and reports the sitemap size.
- Redirect and Canonicalization: It examines redirect and canonicalization behavior.
- Error Handling: It shows what the domain returns for a URL that does not exist.
- Third-Party Resources: It lists third-party hosts, cookies, and trackers used by the site.
- Common Pages: It verifies the existence of about, contact, privacy, and terms pages at their usual paths.
What will the domain analyzer not tell me?
The domain analyzer does not provide traffic estimates, domain authority scores, keyword rankings, or any SEO-related metrics. These aspects cannot be determined by simply inspecting a domain and require different tools and methodologies to assess. Additionally, the tool does not guarantee compliance with any laws or regulations, nor does it make promises about the website’s performance or reliability.
What if a site blocks the domain analyzer check?
If a website blocks automated requests, such as through a Cloudflare interstitial or by returning a 403 error to bots, the domain analyzer will still produce a report. This report will be labeled as “blocked” and will not include any data derived from the page content. However, it will still show certificate, DNS, registration, and robots.txt information because these are served to everyone.
Is my privacy protected when using the domain analyzer?
Yes, your privacy is protected. When you use the domain analyzer, the tool queries the domain registry over RDAP and an IP geolocation service to build the report. This process does not involve collecting or storing any personal information about the user. The reports are public and cached for 14 days, but no user-specific data is retained.
How does the domain analyzer handle CDN-hosted sites?
For sites behind a Content Delivery Network (CDN), the location shown in the report is where the responding server sits, which is typically the CDN edge server. This means the location may not reflect the actual geographical location of the company or organization that owns the domain.
What is the purpose of the table in the report?
The table in the report compares what the domain analyzer measures directly against what it does not provide. This helps users understand the scope of the tool and what aspects of a website it can and cannot assess.

How does the tool handle sites that block automated requests?
The tool still generates a report labeled 'blocked' for sites that block automated requests. It provides certificate, DNS, registration, and robots.txt data but does not extract any content from the page. This ensures you get some information even when full access is restricted.
What information is available about a site's registration and hosting?
The tool shows the site's registration date, registrar, and server location. It also details the network and whether the site is behind a CDN. This helps understand the site's operational background and potential geographical influences.
Can the tool identify the platform or CMS a site is using?
Yes, the tool detects platform fingerprints and published schema.org types. This can help identify the CMS or platform a site is built on. It's useful for understanding the site's technical foundation.
What details does the tool provide about a site's structure and content?
The tool analyzes robots.txt rules, including whether GPTBot and ClaudeBot are blocked, and sitemap size. It also checks for the existence of about, contact, privacy, and terms pages. This provides insights into the site's organization and content accessibility.
How does the tool report on third-party elements and redirects?
The tool lists third-party hosts and cookies and analyzes redirect behavior. This helps identify external resources and track how the site directs traffic. It's valuable for understanding the site's reliance on third parties and user navigation experience.
