HTTP Status Codes for SEO: 200, 301, 404, 410 Explained

A server returning 200 OK on a broken, empty page is arguably worse for SEO than an honest 404. Google calls this a soft 404, and it quietly wastes crawl budget while telling search engines everything is fine when it clearly isn't. HTTP status codes are three-digit messages most visitors never see, yet they shape how Googlebot understands your entire site.

HTTP status codes for SEO are the three-digit server responses, 200, 301, 404, 410, and dozens more, that tell search engines whether a page loaded successfully, moved, disappeared, or failed, directly shaping how efficiently a site gets crawled, indexed, and ranked.

We covered the crawling pipeline these codes feed into in our crawling and indexing guide. Status codes are the raw signal that pipeline reads on every single request.

The Five Status Code Classes

200 OK: The Response You Actually Want

According to Conductor's guide to HTTP status codes and SEO, a clean 200 response on genuinely complete, useful content is the baseline every important page should return, with nothing more complicated required.

301 vs. 302: The Distinction That Costs Sites Traffic

According to DigitalApplied's 2026 HTTP status codes reference, 301 permanent redirects consolidate ranking signals from the old URL to the new one; 302 temporary redirects do not. Migration mistakes here cost real traffic.

# Apache .htaccess: correct permanent redirect
Redirect 301 /old-page.html https://www.example.com/new-page

# NGINX equivalent
rewrite ^/old-page\.html$ https://www.example.com/new-page permanent;

"permanent" in NGINX and "301" in Apache both signal the same thing: this move is final

404 vs. 410: Which One Actually Removes a Page Faster

According to dbeta's guide to HTTP status codes for SEO, both codes tell Google a page is not live, but 410 states it explicitly and permanently, while 404 leaves the door open to reappearing.

# Apache: serve a proper 410 for permanently removed content
Redirect 410 /discontinued-product

A one-line rule, but a meaningfully clearer signal than a generic 404

The Soft 404 Trap

503 for Maintenance, Never 404

According to KelVPN's complete guide to HTTP status codes, returning 503 with a Retry-After header during planned downtime tells Google to re-check later instead of treating the outage as permanent removal.

# Correct maintenance mode response
HTTP/1.1 503 Service Unavailable
Retry-After: 3600

Retry-After in seconds tells crawlers exactly when to come back and check again

Quick Reference: Status Codes and SEO Impact

The 4xx Codes Beyond 404

According to SE Ranking's complete list of HTTP status codes for SEO experts, 401 Unauthorized and 403 Forbidden indicate access restrictions rather than missing content, and should never appear on pages meant to be publicly indexed.

A 429 Too Many Requests code signals rate limiting, often triggered when a crawler requests pages faster than a server can comfortably handle. Sustained 429 responses can slow how thoroughly Googlebot crawls a site over time.

Server Errors and What They Signal Over Time

According to DefiniteSEO's guide to HTTP status codes and SEO, occasional 500 errors are normal on any site, but sustained 5xx responses signal instability, and Google reduces crawl rate on sites it perceives as unreliable.

This creates a compounding problem. A site already struggling with server errors gets crawled less frequently as a direct consequence, which then slows how quickly fixes and new content actually reach the index once resolved.

Diagnosing Status Code Issues With Search Console

According to Webyes' guide to HTTP status codes and SEO fixes, the Page Indexing report surfaces exactly which URLs are returning errors, letting teams prioritize fixes for pages that previously ranked or drove traffic over ones that never mattered much.

After deploying a fix, checking back within 48 to 72 hours and using URL Inspection to request recrawling confirms the correction actually took effect, rather than assuming it worked and moving on without verification.

Redirect Chains Quietly Leak Ranking Signal

According to DigitalApplied's reference guide referenced earlier, each redirect hop in a chain, URL A to URL B to URL C, can leak a small amount of ranking signal along the way. Keep redirects to a single hop wherever possible.

# Verify redirects resolve directly, not through multiple hops
curl -I -L https://www.example.com/old-page

The -L flag follows every redirect in the chain, revealing exactly how many hops occur

Building Status Code Discipline Into a Publishing Workflow

According to Yoast's guide to HTTP status codes and what they mean for SEO, checking Search Console's indexing section regularly, rather than only after something visibly breaks, catches drift before it accumulates into a larger problem.

Treating status code health as an ongoing habit, not a one-time technical audit, matters especially on larger sites where content gets deleted, moved, and restructured constantly as part of normal operations.

A simple internal checklist helps: before deleting any page, decide deliberately between a redirect, a 404, or a 410, rather than letting the default server behavior decide by accident.

That one deliberate choice, repeated consistently, prevents most of the status code problems covered throughout this guide.
