HTTP 200 OK is the standard 2xx success code (RFC 9110): the server found the resource and is returning it. For a web page it's the code you want — but it's necessary, not sufficient. Google's own docs say the indexing pipeline 'may index the content, but that's not guaranteed'; quality, duplication, thin content, and noindex are all judged on top of the 200. The classic trap is the soft 404: a URL that returns 200 while its content reads like an error or an empty page, which Google detects at the content layer and reports as a soft 404 in Search Console regardless of the code. Contrast 200 (success + real body) with 204 (success + empty body, treated like a soft 404) and 304 (a caching signal, not an indexing decision). Match the code to reality — gone → 404/410, moved → 301, duplicate → canonical tag — and always confirm what Googlebot itself received via URL Inspection or logs, not just what your browser sees.

TL;DR — 200 OKHTTP 200 OK is the standard 2xx success status code, meaning the server received, understood, and fulfilled the request and is returning the resource. It's the code every page you want indexed should return — but a 200 alone doesn't guarantee Google will index the page. is the standard 2xx success code (RFC 9110 §15.3.1): the server fulfilled the request and, for GET/HEAD, the body is a representation of the resource.

What 200 means in the spec

RFC 9110 (HTTP Semantics) is the current authority, and §15.3.1 is blunt: “The 200 (OK) status code indicates that the request has succeeded.” What the body contains depends on the request method. For the methods that matter for pages — GET and HEAD — the content is a representation of the target resource. The RFC also qualifies this: aside from responses to CONNECT, a 200 is expected to carry content unless the message framing explicitly signals zero length — so “a 200 always has a body” is a shorthand, not an absolute. In practice, for a page you want indexed, that shorthand is the target: a real body, not an empty one. A 200 is also “heuristically cacheable” by default unless a cache-control directive says otherwise, which is why validator headers like ETag and Last-Modified matter on pages that get re-crawled a lot. Evidence for this claim RFC 9110 defines 200 OK as indicating that the request succeeded; the response content depends on the request method. Scope: HTTP semantics for 200 responses; this does not guarantee search indexing. Confidence: high · Verified: IETF: RFC 9110 §15.3.1 — 200 OK

Technically speaking, 200 isn’t only for pages. The RFC lays out what “success” means per method:

Request methodA 200 body represents
GETthe target resource
HEADthe target resource, but without transferring the body
POSTthe status of, or result from, the action
PUT, DELETEthe status of the action
OPTIONScommunication options for the resource

For non-GET methods you’ll often not see a 200 — MDN notes successful PUT or DELETE requests “often do not result in a 200 OK response,” with 201 Created or 204 No Content being more common. None of that is SEO-relevant for page URLs; the one line to carry forward is that for a document you want indexed, 200 with a real body is the target.

Necessary, not sufficient, for indexing

This is the single most important thing to get right, and it’s where most competing glossary pages are flatly wrong. They say “200 means the page gets indexed.” Google’s own documentation says otherwise. For a 200, Google “passes on whatever it received to the next processing step… For Google Search, the next system is the indexing pipeline. The indexing systems may index the content, but that’s not guaranteed.” Evidence for this claim Google passes a 2xx response to its indexing pipeline, which may index the content but does not guarantee that it will do so; error-like content can be classified as a soft 404. Scope: Google Search handling of 2xx page responses and soft 404s. Confidence: high · Verified: Google: HTTP status codes and Search

So the 200 is a contract about the HTTP response, not a promise about the page’s fate in Search. After the 200, Google independently evaluates:

  • Quality — thin, low-value, or auto-generated pages may not be indexed.
  • Duplication — a near-duplicateThe same or very similar primary content reachable at more than one URL. There's no general duplicate content penalty — the real costs are possible signal dilution, the wrong URL getting chosen, and less-efficient crawling. of a stronger URL may get folded into that URL rather than indexed on its own (this is what the canonical-tag exists to control).
  • Directives — a noindex in a meta tag or X-Robots-Tag header keeps the page out even with a perfect 200.

Patrick’s Ahrefs guide draws the same line at the family level: “Most 2xxs will allow pages to be indexed. However, 204s will be treated as soft 404sA soft 404 is a URL that returns a success status code (usually 200 OK) even though the page is empty, missing, or shows a 'not found' message. It isn't a status code a server sends — it's a label search engines apply after comparing the response code against the rendered content, and they treat the page like a 404 for indexing. and won’t be indexed.” The 200 makes a page eligible; it doesn’t make it indexed.

The soft 404 trap

The sharpest illustration of “200 isn’t the whole story” is the soft 404. Google’s status-codes doc spells out the mechanism: “If the content suggests an error for Google Search, an empty page or an error message, Search ConsoleGoogle's free tool for monitoring crawling, indexing, and search performance. will show a soft 404 error.” Notice what that means — the classification is based on the rendered content, not the HTTP code. Google’s indexing pipeline looks past the 200 at what’s actually on the page, and if it reads like “not found,” it’s bucketed and reported like a real 404.

The gut-check cases: a discontinued product whose page now loads an empty template, a deleted article that still returns a 200 shell, a filtered category page or search result with zero items and a “nothing here” message. Each returns a technically correct 200 while telling both users and Google there’s nothing to see.

This site has a dedicated soft-404-errors article for the detection mechanics and fixes — I won’t re-run them here. The takeaway for the 200 discussion is simply: returning 200 on a page that’s genuinely gone is the setup for a soft 404. The fix is to make the code match reality.

Worth a bounded aside since it comes up in API and monitoring circles: the HTTP layer and the application layer can disagree. An API endpoint can send 200 with a JSON error object sitting in the body; a page can send 200 while a backend dependency failed silently and rendered a broken block instead of the real content. The status line says “delivered fine” — that’s all it’s claiming. Whether the payload is actually correct is a separate question the status code doesn’t answer. Practitioners are genuinely split on whether an API should signal an error with a non-200 status or with a 200 wrapping an error payload; that’s a contract each team chooses, not an HTTP rule. For this site’s SEO focus, the page-level version of the same problem is the soft 404 above — the fix is the same in spirit: don’t trust the status line alone, look at what the body actually contains.

200 vs. 204 vs. 304 — don’t conflate them

Three codes people mix up, and only one of them is the “here’s your page” success:

CodeClassBodyWhat it meansSEO handling
200 OK2xxReal content expectedSuccess — here’s the resourceEligible for indexing (not guaranteed)
204 No Content2xxEmpty by designSuccess, intentionally no bodyTreated like a soft 404 on a page URL — see 204-no-content
304 Not Modified3xxNone”Use your cached copy” (conditional request)A caching signal, not an indexing decision

204 is a genuine success code, but its empty body gives a crawlerA crawler — also called a spider or bot — is an automated program that fetches web pages, extracts their links, and queues new URLs to visit. Search engines use crawlers to discover and download content for their index. nothing to index — so on a page URL it lands in the soft-404 bucket (that’s a separate article; don’t confuse the empty-body case with a normal 200). 304 isn’t even in the same family — it answers a conditional request (If-None-Match / If-Modified-Since) by telling the client its cached copy is still current. It carries no body and says nothing about whether to index; it’s a crawl-efficiency mechanism, not a duplicate-of-200. The common “200 vs 304, aren’t those the same?” question conflates a caching optimization with a success response.

Confirm what Googlebot actually sees

Here’s a gap almost every competing article skips: different requesters can get different codes for the same URL. Your browser can see a clean 200 while GooglebotGooglebot is Google's web crawler — the software that fetches pages so Google can index and rank them. It comes in two variants, Googlebot Smartphone (primary, under mobile-first indexing) and Googlebot Desktop, and runs an evergreen Chromium renderer. gets something else — sometimes deliberately (cloaking, which is a spam violation under Google’s Search Essentials), more often accidentally through WAF/bot-blocking rules, geoGenerative Engine Optimization — visibility inside AI answer engines.-IP targeting, CDN edge logic, or an A/B-testing setup that misfires for bots.

So “it’s 200 in my browser” is not proof “Google sees 200.” The correct diagnostic is to check what Googlebot itself received:

  • GSC URL Inspection — run a Live Test to see the status and rendered content Google fetches, not what your machine sees.
  • Server / CDN logs — the ground truth for what code each user-agent actually got.

A plain curl -I from your terminal is useful, but it’s just one more requester that can hit different edge rules than Googlebot — treat it as a data point, not the final word.

What “healthy” looks like: your important, canonical URLs consistently return 200 with real content, and the pages that should be gone or moved return 404/410 or a 301 instead of a misleading 200.

TIP Check the code and destination without mistaking 200 for quality

  1. Check the canonical URLs and expand any redirecting rows.
  2. Inspect every 200 page for real, intent-matching content and soft-404 signals.
  3. Confirm crawler-specific discrepancies with URL Inspection and verified access logs.

The decision, in one line

Match the code to reality. Wanted in the index → 200 with substantive content. Gone for good → 404 or 410 (see 404-not-found). Moved → 301. A duplicate of another URL → point a canonical tagA rel=\"canonical\" annotation — in the HTML <head> or an HTTP Link header — that tells search engines which URL is the preferred version of duplicate or near-duplicate content. at the preferred version rather than trying to force a non-200 code. The 200 is the green light for pages that genuinely deserve one — nothing more, nothing less.
