HTTP Status Codes: Complete Guide (200, 301, 302, 404, 500+)

Understanding HTTP status codes (2xx, 3xx, 4xx, 5xx) and their SEO implications is crucial for website optimization and troubleshooting.

200

OK - Success

SEO Impact: Positive ✅

The request was successful and the page loaded correctly. This is the ideal status code for all your important pages.

SEO Best Practices:
  • • Search engines can crawl and index the page normally
  • • No negative impact on search rankings
  • • Ensure fast loading times for better user experience
  • • Monitor for consistent 200 responses across all important pages
301

Moved Permanently

SEO Impact: Neutral to Positive ✅

The page has permanently moved to a new location. Search engines will transfer ranking signals to the new URL.

SEO Best Practices:
  • • Passes 90-99% of link equity to the new URL
  • • Use for permanent site restructuring or domain changes
  • • Update internal links to point directly to new URLs
  • • Avoid redirect chains (301 → 301 → 200)
  • • Monitor for proper implementation across all platforms
302

Found (Temporary Redirect)

SEO Impact: Caution ⚠️

Temporary redirect that doesn't pass full link equity. Search engines may continue indexing the original URL.

SEO Considerations:
  • • Use only for truly temporary redirects (A/B tests, maintenance)
  • • Search engines may not transfer ranking signals
  • • Can cause indexing confusion if used long-term
  • • Convert to 301 redirects when the move becomes permanent
  • • Monitor to ensure it's not being used unintentionally
307

Temporary Redirect

SEO Impact: Caution ⚠️

Similar to 302 but preserves the HTTP method. Used for temporary redirects where the request method must remain unchanged.

SEO Considerations:
  • • Maintains the original HTTP method (POST, PUT, etc.)
  • • Treated similarly to 302 by search engines
  • • Use for short-term redirects only
  • • Consider 308 for permanent method-preserving redirects
308

Permanent Redirect

SEO Impact: Positive ✅

Permanent redirect that preserves the HTTP method. Similar to 301 but maintains the original request method.

SEO Best Practices:
  • • Transfers ranking signals like a 301 redirect
  • • Use when the HTTP method must be preserved
  • • Ideal for API endpoints and form submissions
  • • Less commonly used than 301 for regular pages
400

Bad Request

SEO Impact: Negative ❌

The server cannot process the request due to client error. This prevents proper crawling and indexing.

SEO Issues & Solutions:
  • • Search engines cannot crawl or index the page
  • • Check for malformed URLs in your sitemap
  • • Validate URL structure and parameters
  • • Fix server configuration issues
  • • Monitor crawl errors in Google Search Console
401

Unauthorized

SEO Impact: Negative ❌

Authentication required to access the resource. Search engines cannot index password-protected content.

SEO Considerations:
  • • Content won't be indexed by search engines
  • • Use for private/member-only content intentionally
  • • Avoid accidentally protecting public pages
  • • Consider using noindex instead for temporary hiding
403

Forbidden

SEO Impact: Negative ❌

Server understands the request but refuses to authorize it. Often due to permission issues or IP blocking.

SEO Issues & Solutions:
  • • Search engines cannot access the content
  • • Check robots.txt for accidental blocking
  • • Verify server permissions and .htaccess rules
  • • Ensure Googlebot isn't being blocked
  • • Review IP whitelist/blacklist settings
404

Not Found

SEO Impact: Negative ❌

The requested resource was not found. One of the most common issues affecting SEO performance.

SEO Issues & Solutions:
  • • Page will be deindexed by search engines
  • • Fix broken internal links immediately
  • • Set up 301 redirects for moved content
  • • Create custom 404 pages with helpful navigation
  • • Monitor 404 errors in Google Search Console
  • • Update sitemaps to remove non-existent URLs
410

Gone

SEO Impact: Neutral ⚪

Resource permanently removed and will not be available again. More definitive than 404 for intentionally removed content.

SEO Best Practices:
  • • Faster deindexing than 404 errors
  • • Use for permanently discontinued products/pages
  • • Helps search engines understand intentional removal
  • • Better than 404 for deliberate content removal
  • • Remove from sitemaps and internal links
500

Internal Server Error

SEO Impact: Severely Negative ⛔

Server encountered an unexpected condition. Critical issue that prevents crawling and can lead to deindexing.

Urgent Actions Required:
  • • Fix immediately - critical for SEO
  • • Check server logs for error details
  • • Monitor uptime and server performance
  • • Pages may be deindexed if errors persist
  • • Set up monitoring alerts for 500 errors
  • • Communicate with hosting provider if needed
502

Bad Gateway

SEO Impact: Severely Negative ⛔

Server acting as a gateway received an invalid response from upstream server. Often related to CDN or proxy issues.

SEO Issues & Solutions:
  • • Search engines cannot access content
  • • Check CDN and proxy configurations
  • • Verify upstream server connectivity
  • • Monitor load balancer health
  • • Implement proper error handling and fallbacks
503

Service Unavailable

SEO Impact: Temporary Negative ⚠️

Server temporarily unable to handle requests. Often used during maintenance or when server is overloaded.

SEO Best Practices:
  • • Use with Retry-After header for maintenance
  • • Temporary impact if resolved quickly
  • • Avoid extended 503 periods
  • • Inform search engines of planned maintenance
  • • Monitor server capacity and scaling
