How to use this tool
1. Input Destination URL
Enter the full URL you want to test (e.g. `https://faisalrafique.com`).
2. Inspect Status & Headers
View the exact HTTP status code returned (200 OK, 301, 404, 410, 503) and response headers.
3. Check SEO Impact
Review how search engines interpret this status code (indexable, soft-404, canonical redirect, or server error).
4. Test Alternative Codes
Use the status code reference library to lookup definitions, specifications, and troubleshooting guides.
Formula or logic used
HTTP Status Classes & SEO Interpretation
HTTP status codes are divided into 5 standard classes defined by RFC 9110, each triggering distinct search crawler behaviors.
2xx Success: HTTP 200 (Standard indexable resource) or 204 (No content).3xx Redirection: HTTP 301 (Permanent equity transfer), 302/307 (Temporary), 304 (Not modified/Cached).4xx Client Error: HTTP 404 (Not found - dropped from index), 410 (Gone - permanently purged faster than 404), 429 (Too many requests/Rate limited).5xx Server Error: HTTP 500 (Internal server error), 502 (Bad gateway), 503 (Service unavailable - signals temporary maintenance, preserves rankings).
Examples
Example 1: Live Production Landing Page
Ideal response indicating healthy server performance and fully indexable content.
Example 2: Permanently Deleted Product Page
HTTP 410 signals permanent removal, purging the URL from search engine indexes faster than a standard 404.
Common use cases
Soft 404 Detection
Identify pages that visually display 'Not Found' to visitors but mistakenly return HTTP 200 OK to search engines.
Server Maintenance Management
Verify that maintenance windows return HTTP 503 Service Unavailable with a Retry-After header.
Redirect Protocol Verification
Check whether URLs return permanent 301 vs temporary 302 redirects.
API Endpoint Health Auditing
Inspect backend REST APIs for proper CORS headers and error response payloads.

Frequently asked questions
What is a Soft 404 error?
A Soft 404 occurs when a page tells human users it does not exist (e.g. 'Sorry, page not found') but returns an HTTP 200 OK response header to search engines. Google Search Console will flag this as an error because search engines waste crawl budget indexing empty pages.
What is the difference between HTTP 404 and HTTP 410?
Both indicate missing pages, but HTTP 404 means 'Not Found' (search engines will re-crawl several times in case the removal was accidental). HTTP 410 means 'Gone' permanently, prompting Googlebot to purge the URL from the index immediately.
What status code should be used during scheduled website maintenance?
Always return HTTP 503 (Service Unavailable) along with a `Retry-After: <seconds>` header. This tells search engines your site is temporarily offline and preserves all existing search rankings.
Does TTFB (Time To First Byte) affect Google rankings?
Yes. High TTFB (>800ms) negatively impacts Core Web Vitals, degrades user experience, and causes Googlebot to reduce its crawl rate across your domain.
