2xx
Successful response
The page responded successfully. Public indexable pages should normally return a stable 200.
HTTP Status Checker
HTTP Status Checker
Check a page's HTTP status, redirect chain and search-related response headers.
Example: Enter a full page URL. The checker follows redirects and reports the final response.

HTTP SEO
What is an HTTP status check?
An HTTP status check requests a public page and records the server status, redirect chain, final URL, response IP, headers and request time.
It focuses on the HTTP signals a crawler sees first. It does not change site content or store a history record.
3xx
Redirect
The URL moved. Long-term moves normally use 301 or 308 with as few intermediate hops as possible.
4xx
Client error
The page is missing, restricted or rejected, so crawlers usually cannot fetch it normally.
5xx
Server error
The server or an upstream failed. Persistent errors can reduce crawler request frequency.
Why check HTTP status?
A page opening in one browser does not guarantee that crawlers can fetch it consistently. Redirects, 4xx, 5xx and response directives can affect crawling and indexing.
Confirm crawlability
Identify 200, 4xx, 5xx and abnormal redirects while separating page errors from request failures.
Reduce redirect loss
Inspect every hop and find long chains, loops or redirects that fall back to HTTP.
Find indexing blocks
Read X-Robots-Tag and detect server-level noindex or nofollow directives.
How does the checker work?
The checker makes a controlled HTTP request without user credentials and applies safety limits to targets, redirects and response size.
- 01
Normalize the URL
Validate HTTP/HTTPS, remove fragments and reject credentials or private targets.
- 02
Request the page
Resolve a public address, connect to the pinned IP and record status, headers, IP and timing.
- 03
Follow redirects
Recheck every redirect target, follow at most eight hops and detect loops or invalid protocols.
- 04
Explain the result
Generate practical recommendations from the final status, chain and X-Robots-Tag.
How should the result be read?
The status shows how the server handled the request; diagnostics explain possible crawl and indexing impact.

HTTP status checker FAQ
Does a 200 status guarantee indexing?
No. A 200 only means the HTTP request succeeded. Robots rules, canonical, noindex, content quality and internal links still affect crawling and indexing.
When should I use 301 versus 302?
Use 301 or 308 for a long-term move. Use 302 or 307 for a temporary change, based on the migration strategy.
Why does a browser work while the checker receives 403?
The server may apply rules based on User-Agent, IP, region or headers. Search crawlers may face the same restriction, so review logs and CDN rules.
Does the check execute JavaScript?
The current version reads the server HTTP response and does not execute JavaScript. It is designed for server-rendered HTML and HTTP signals.
How long are results stored?
Results remain on the current page. A short server cache may speed up repeats, but no history record is written.
