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.
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
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
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
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
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
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
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
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
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
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
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
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
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
