HTTP Header Checker for response clarity
Inspect HTTP response headers for any public URL. Review status codes, redirects, security headers, cache rules, compression, raw headers and SEO-specific header signals before you move into the detailed output.

HTTP Header Checker
Inspect status codes, response headers, security headers, cache rules, compression, redirects, and SEO header signals.
Check options
Keep the public check lightweight while controlling redirects, request method, and output depth.
Follow redirects
Show the final response after following redirect hops.
Show raw headers
Include a raw export-friendly view of the response headers.
Separate SEO-specific signals
Group canonical, robots, indexing, language, and content-type signals into their own tab.
Free public checks are limited to 3 uses/day. CAPTCHA may appear for protection.
Response details that browsers do not always show clearly.
The checker focuses on URL-level HTTP responses: status codes, redirect behaviour, parsed response headers, security protections, cache rules, compression and SEO-specific directives.
Use it during internal linking audits, content optimisation, technical SEO reviews, website migrations and content hub planning.
Inspect status codes and redirects
Review final HTTP status, redirect hops, destination URLs and Location headers so SEO-critical pages respond as intended.
Organise response headers by purpose
Separate raw server response details into readable groups for security, cache, SEO, compression, server and other header categories.
Check common browser protections
Highlight headers such as HSTS, Content-Security-Policy, X-Content-Type-Options, X-Frame-Options and Referrer-Policy.
Surface crawl and indexability directives
Review X-Robots-Tag, canonical header signals, Content-Type, Content-Language and body-aware robots meta hints when GET scanning is enabled.
Headers shape how pages are handled before rankings react
HTTP headers help browsers, crawlers, CDNs and search engines understand how a page should be served, cached, protected, redirected and indexed. Poor header configuration can affect crawlability, performance, security and SEO visibility.
Confirm pages are available
Validate whether important URLs return expected 2xx, 3xx, 4xx or 5xx responses before crawlers and users hit problems.
Make developer handoff easier
Copy raw headers and focused findings so technical SEO issues can move cleanly into QA, tickets and release reviews.
Review security, cache and SEO together
See how headers affect crawlability, caching, performance, browser protections and indexability without turning the page into a full audit report.
From public URL to structured header review in four steps.
The landing page stops at setup. The detailed result opens after submission inside the checker output experience.
Enter a public URL
Add one HTTP or HTTPS URL such as https://example.com/page. If you paste only a domain, add the protocol first.
Choose check options
Control redirect following, public hop limit, request method, user-agent mode, timeout and optional raw or SEO-specific grouping.
Run the header check
Wranker sends the request, follows redirects where enabled, parses headers and prepares a structured technical response.
Review the output workspace
Open tabs for overview, response headers, security, cache and compression, SEO signals, redirects and raw headers after submission.
Use header checks before crawlability, QA or launch decisions.
HTTP headers are small, but they can change how users, crawlers, caches, CDNs and browsers handle a page. Use the checker when URL-level response behaviour matters.
Technical SEO specialists
Check status, redirects, cache rules, compression and SEO directives while diagnosing crawlability or indexability issues.
SEO agencies
Add focused header checks to technical audit workflows, migration QA and client-facing developer recommendations.
Developers
Inspect raw response headers during QA, release validation, CDN changes and server configuration reviews.
Marketing teams
Validate campaign landing pages before launch so redirects, status codes and indexability signals are not accidentally misconfigured.
Continue the technical SEO workflow.
Pair header checks with redirect, availability, indexability and SSL reviews when diagnosing URL-level SEO health.
URL Redirect Path Checker
Review redirect chains, temporary redirects, final destinations and hop-level response details.
OpenServer Status Checker
Check live HTTP status and availability for important URLs before deeper diagnosis.
OpenIndexability Checker
Review whether a URL is likely eligible for indexing based on crawl and directive signals.
OpenSSL Certificate Checker
Validate HTTPS certificate status, expiry and issuer details as part of technical SEO workflows.
HTTP header checker questions, . answered
Practical answers about response headers, redirects, HEAD and GET requests, security headers, cache rules, compression and SEO directives.
An HTTP Header Checker is a tool that inspects the server response for a URL. It can show status code, response headers, redirects, security headers, cache rules, compression and SEO header signals.
HTTP response headers are server-sent instructions and metadata that describe how a browser, crawler or cache should handle a response. Examples include Content-Type, Cache-Control, Location, X-Robots-Tag and Strict-Transport-Security.
Yes. The tool can follow redirects up to the selected public redirect limit and show the final response, redirect hops and Location headers.
The default public method is Auto, which tries a HEAD request first and uses a GET fallback when HEAD is blocked, incomplete or misleading.
Yes. It can highlight common security headers such as Strict-Transport-Security, Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, Referrer-Policy and Permissions-Policy.
Yes. It can review cache-related headers such as Cache-Control, Expires, ETag, Last-Modified, Vary and Age where available.
Yes. It can detect response compression signals such as gzip, Brotli or deflate through headers like Content-Encoding and Vary: Accept-Encoding.
Yes. It can review SEO-relevant signals such as HTTP status code, X-Robots-Tag, Link rel canonical headers, Content-Type and Content-Language.
Robots meta tags require reading page HTML. Header-only checks cannot always detect them. If GET or lightweight meta scan is enabled, the tool may inspect a limited portion of HTML for robots meta data.
Yes. Public exports may include CSV, PDF, JSON and TXT. You can also copy the summary, response headers, security findings or raw headers where available.
