A 404 error is not automatically an SEO problem—and it is not a Google penalty. On October 28, 2026, Google revisited this longstanding principle in a Halloween-themed episode of its Non-Canonical Cabinet video series. As Barry Schwartz reported at Search Engine Roundtable, the video addresses misconceptions about missing pages, redirects, crawl budget and Search Console warnings.
This is not a newly introduced ranking factor or a change in how Google indexes websites. It is a useful reminder that technical SEO should focus on meaningful errors rather than treating every missing URL as an emergency.
Why Google says normal 404 errors are not scary
An HTTP 404 Not Found response tells a browser or crawler that the requested URL does not exist. That is a normal part of the web: products are discontinued, articles are removed, old URLs disappear and people mistype addresses.
Google's official Search Console guidance says 404 responses generally do not harm a site's search performance when the URLs genuinely should not exist. A missing URL may eventually be removed from the index, but that is different from a sitewide penalty against other functioning pages.
There is an important exception to the practical interpretation: if a valuable page unexpectedly returns 404, that URL cannot serve its intended content and may lose search visibility. The absence of a general penalty does not mean that every 404 should be ignored.
404, 410, 301 and 200: what each response means
Technical SEO decisions start with the intended state of a URL. Different HTTP responses communicate different outcomes:
- 404 Not Found: the requested page does not exist. Appropriate when no relevant replacement is available.
- 410 Gone: the resource has been intentionally removed. Google currently treats 410 similarly to 404 for indexing purposes.
- 301 Moved Permanently: the page has moved to a relevant new address. Use it when a genuine successor exists.
- 200 OK: the server successfully returns a page. Returning 200 for a page that merely displays “not found” can create a soft 404.
Google's HTTP status documentation explains that ordinary 4xx responses tell its indexing pipeline that content is unavailable. Previously indexed URLs returning these codes are removed from the index over time, while newly encountered missing pages are not processed for indexing.
Google's three-step framework for deleted URLs
The October video summarizes a simple decision process. First, if an old URL has a truly relevant replacement, redirect visitors to it. Second, if the content is permanently gone and no suitable equivalent exists, leave a correct 404 response or use 410. Third, make the missing-page experience useful to visitors with a clear explanation and helpful navigation.
These steps can be applied to most websites without complicated automation. The important judgment is whether the destination actually meets the visitor's original intent.
Why redirecting every 404 to the homepage is a bad idea
A common shortcut is to send all missing URLs to the homepage with a 301 redirect. It may make an error report look cleaner, but it rarely solves the underlying problem.
Someone following a link to a discontinued product, a removed support article or a specific event page expects relevant information. A generic homepage may not provide that information. Google warns that irrelevant redirects can confuse users and may be interpreted as soft 404 behavior.
A redirect should therefore be based on content equivalence, not simply on the desire to eliminate a warning. When no suitable destination exists, a properly designed 404 page is often the more accurate and useful response.
Soft 404s: when the status code and page content disagree
A soft 404 occurs when Google determines that a page behaves like an error or lacks meaningful content even though the server returns a success response, typically HTTP 200. For example, a page may display “This product no longer exists” while reporting 200 OK.
Google's technical documentation identifies other causes, including nearly empty pages, missing server-side resources and JavaScript rendering failures.
To diagnose a soft 404, inspect the URL in Google Search Console, check the actual HTTP response and examine the rendered page. If the resource is gone, return 404 or 410. If it moved, use a relevant 301. If the content should exist, repair the rendering or loading problem instead of deleting the page.
Do 404 errors waste crawl budget?
Google also revisited the idea that normal 404 responses drain crawl budget. Its crawler documentation states that 4xx responses other than 429 do not reduce the site's overall crawl rate in the same way server overload responses can.
That does not mean broken internal links are desirable. A site generating large numbers of unnecessary URLs, inconsistent navigation or invalid sitemap entries still creates avoidable maintenance work and poor user experiences. But the mere presence of legitimate 404 responses is not evidence that Google is withholding crawling from healthy pages.
429 and 5xx errors are a different category of problem
Unlike an ordinary missing page, HTTP 429 Too Many Requests indicates rate limiting, while 5xx errors indicate server-side failures. Google treats these responses as signals that a server may be overloaded or unavailable and can temporarily reduce crawling.
Persistent server failures can eventually affect indexed URLs because Google cannot reliably retrieve their content. This makes repeated 429, 500, 502 and 503 responses more operationally urgent than a long list of genuinely removed URLs.
Site owners should investigate server logs, hosting capacity, application exceptions and rate-limiting rules when these errors recur. Blocking Googlebot accidentally through infrastructure protections can have consequences that are very different from returning 404 for a deleted article.
How to prioritize 404s in Google Search Console
Search Console may report many URLs under “Not found (404).” Instead of counting every entry as a defect, classify them by business value and cause.
High priority: pages that should be live, important URLs linked from site navigation, recently moved content without redirects, and URLs still submitted in XML sitemaps. These can affect users and the discoverability of content the site intends to keep available.
Medium priority: old URLs with meaningful backlinks, referral traffic or a clear replacement page. Consider relevant redirects when they preserve visitor intent.
Low priority: deliberately deleted pages with no successor, random malformed URLs and requests for addresses that never existed. A correct 404 response is usually sufficient.
Google's Page indexing report documentation advises prioritizing 404s that the website itself links to or includes in a sitemap. That is a practical way to distinguish maintenance issues from harmless background noise.
Practical examples for ecommerce and publishers
Discontinued product: if a near-identical replacement exists and meets the same need, redirect to that replacement. If not, consider a helpful 404 page with navigation to related categories; do not assume the category homepage is always equivalent.
Article moved to a new URL: use a permanent redirect from the old address to the new article and update internal links and sitemaps.
Deleted news article: if no equivalent article remains, 404 or 410 can be appropriate. Preserving an archive may be preferable when the content still has editorial or historical value, but that is a publishing decision.
Typo in an internal link: fix the source link first. If the misspelled URL is frequently used externally, a redirect may also help.
Invalid URLs created by a scraper, bot or malformed query: there is usually no reason to redirect every invented address. Make sure the server responds correctly and investigate only if the pattern indicates an application or security issue.
A technical checklist for site owners
When reviewing a 404 report, ask whether the URL should exist, whether it appears in internal links or XML sitemaps, whether it has a meaningful successor, whether the server returns the intended status code, and whether users receive useful guidance. Then check separately for soft 404s, 429 responses and 5xx failures.
For Laravel, WordPress and custom CMS websites alike, the same principles apply: correct HTTP semantics, sensible redirects and reliable server responses are more valuable than making every Search Console warning disappear.
NetContentSEO assessment
Google's October 2026 video is an evergreen technical SEO reminder, not breaking algorithm news. Legitimate 404s do not create an automatic penalty, and a removed page does not require an arbitrary redirect. The real work is identifying URLs that should function, repairing broken internal links, avoiding soft 404s and responding quickly to server-side problems.
Technical SEO is not about achieving a zero-error dashboard. It is about ensuring that users and crawlers receive accurate signals about which pages exist, which have moved and which are permanently unavailable.
