How to use Website Analyzer
The Website Analyzer fetches a public URL from ToolsHub’s servers and returns a single report covering technical SEO, HTTP status, security headers, SSL, robots.txt, sitemap detection, DNS, and a capped sample of on-page links. Use it when you need a first-pass health check before diving into a specialist tool. JavaScript is not executed, private addresses are blocked, and each section links to a deeper ToolsHub checker so you can keep investigating without starting over.
- Paste a public http(s) URL. example.com is accepted and treated as https://example.com.
- Click Analyze. HTTP, SEO, and security header sections stream in first.
- Read the issue list: missing titles, noindex, weak headers, and mixed content are called out in plain language.
- Use Analyze deeper to open the specialist tool for any section you need to fix.
- Share the result link (it stores the URL in the query string) with a teammate.
What the report includes — and what it does not
The analyzer is a live snapshot of one URL, not a full-site crawl and not a lab performance test. It reads the first HTML response (title, meta, headings, images, links, JSON-LD types), grades security headers, checks the certificate on port 443, fetches robots.txt, looks for a sitemap, resolves DNS A records, and probes up to 12 unique http(s) links found on the page (internal first, SSRF-guarded). It does not execute page JavaScript, crawl the rest of the site, or call PageSpeed Insights. That keeps the check fast, cheap, and safe. If you need Lighthouse numbers or a backlink profile, those are different products; if you need the next DNS, SSL, or schema detail, the in-report links go there.
How to act on a low score
Start with indexability: a 404, a noindex robots tag, or a robots.txt Disallow on the path will hide the page no matter how good the title is. Next, fix the snippet — title around 50–60 characters, description around 150–160, one H1, a self-referential canonical. Then raise the security-header grade (HSTS and CSP move the needle most) and confirm the certificate is not close to expiry. Mixed-content HTTP assets on an HTTPS page should be upgraded or removed. Work top to bottom; the analyzer’s issue list is ordered for that workflow.
| Section | What to do next |
|---|---|
| HTTP | Confirm 200 and the final URL after redirects |
| SEO | Fix title, description, canonical, H1 |
| Security | Add HSTS and CSP, then re-grade |
| Links | Sample of on-page URLs — 404s in the sample, not a site crawl |
| SSL / DNS | Renew certs; verify A records after a migration |
Glossary
- Indexability
- Whether crawlers are allowed to index a URL, based on status codes, robots meta, X-Robots-Tag, and robots.txt.
- Canonical
- The preferred URL for a page, declared with rel=canonical to consolidate duplicate URLs.
- JSON-LD
- A script type that embeds Schema.org structured data in a page for rich results.
- Mixed content
- HTTP resources loaded on an HTTPS page, which browsers block or warn about.
- SSRF guard
- Server-side checks that refuse private, loopback, and link-local addresses so a URL tool cannot scan internal networks.
