Most site owners treat a missing page as a minor inconvenience. The real issue is what the server tells Google when that page is requested — and whether that signal is accurate. A 404 is honest: the server says the page is gone. A soft 404 is dishonest: the server says everything is fine when it isn't. Both affect how Googlebot spends its time on your site, but they do it in different ways and require completely different fixes. Understanding 404 vs soft 404 SEO errors is one of those technical details that quietly separates well-ranked sites from ones that plateau.

What a 404 and a Soft 404 Actually Mean
When a browser or crawler requests a URL, the server returns an HTTP status code alongside whatever content (or lack of it) sits at that address. That status code is the first thing Google reads — and it shapes every subsequent decision about whether to index the page, how often to revisit it, and whether to pass signals through to the rest of your site.
The Standard 404
A 404 status code tells the requester: this resource does not exist. The server is being transparent. Google sees a 404, understands the page is unavailable, and — after confirming this across multiple crawls — removes the URL from its index. There is no ambiguity. The URL is dead; Google treats it accordingly.
A custom 404 page (the "Page Not Found" design your team built) can sit at that URL and still return a proper 404 status code in the HTTP header. The design shown to users and the signal sent to Google are two separate things, which is exactly where soft 404s tend to originate.
The Soft 404
A soft 404 occurs when a URL that should return a 404 instead returns a 200 (OK) status code. The server is telling Google the page exists and loaded successfully — even though the content is a "page not found" message, a blank template, or a near-empty product shell. Google receives conflicting information: the status code says "live page," but the content says "nothing here."
According to Google's own crawling documentation, soft 404s are one of the more common and consequential indexing problems it encounters at scale. The engine may attempt to index these pages, find them thin or duplicate, and either ignore them or treat them as low-quality signals — but it will keep crawling them regardless, burning crawl budget each time.
How 404 vs Soft 404 SEO Impact Differs in Practice
The instinct is to assume a 404 is worse because it is the "error." In reality, a soft 404 is frequently the more damaging of the two — not because of any single page, but because of what happens at scale.
Crawl Budget Consumption
Googlebot allocates a crawl budget to each domain based on server health, site authority, and crawl rate settings. A genuine 404 is processed quickly: the URL is flagged, rechecked a few times over subsequent crawl cycles, then de-indexed. Googlebot stops returning to it. A soft 404, on the other hand, looks like a live page. Google keeps crawling it, keeps attempting to index it, and keeps reassessing it — indefinitely. On large e-commerce or publisher sites with thousands of discontinued product pages or expired content, soft 404s can consume a disproportionate share of crawl budget that should be spent on pages you actually want ranked.
Index Bloat
Soft 404s contribute directly to index bloat — the accumulation of low-value pages in Google's index that dilute the quality signals of your site as a whole. A site where a meaningful proportion of indexed URLs are effectively empty shells is signalling, at a structural level, that its content is unreliable. Genuine 404s do not contribute to index bloat because Google eventually removes them from the index entirely.
Link Equity
If external sites have linked to a URL that now returns a genuine 404, that link equity is lost — but the problem is visible and fixable via a 301 redirect. If a URL returns a soft 404, any inbound links are pointing to a page Google may have already flagged as low-quality. The equity passes to a page that is likely doing your site more harm than good.

Where Soft 404s Most Commonly Originate
Soft 404s are almost always a development or platform issue rather than an editorial one. They tend to appear in predictable places once you know what to look for.
CMS and Platform Defaults
Many content management systems — including some configurations of WordPress, Magento, and Shopify — serve a 200 status code by default when displaying their built-in "not found" templates. The template looks like a 404 to users but signals success to crawlers. This is a server-level configuration issue, not a design one, and it requires a developer to correct the HTTP response header rather than change the page's visual appearance.
Dynamic Pages with No Content
Filtered search result pages (e.g., /products/?colour=yellow&size=xs returning zero results), user profile pages for deleted accounts, and event pages after the event date has passed are all common soft 404 sources. The page template loads; the content does not. The server sees a successful page render and returns 200.
Redirect Chains Resolving to Thin Pages
A URL redirected to a page that itself has almost no content — a category page with no products, a blog tag page with one post — may be flagged by Google as a soft 404 even though the destination technically exists. Google's assessment here is content-based, not purely status-code-based, which is why thin content and soft 404s are closely related problems.
How to Identify Both Error Types on Your Site
The challenge with soft 404s is that standard site monitoring tools do not catch them automatically — because the server is not reporting an error. You need to look specifically for the mismatch between status code and content quality.
Google Search Console
The Pages report in Google Search Console is the fastest starting point. Under the "Why pages aren't indexed" section, Google explicitly flags URLs it has classified as soft 404s. This list represents pages Google has already assessed as problematic — treat it as your priority fix queue, not a background task.
Standard 404s appear in the same report under "Not found (404)" — distinct from the soft 404 classification. Both lists are worth exporting and reviewing on a monthly cadence.
Log File Analysis
Server log files show you exactly which URLs Googlebot is crawling and how frequently. If you see Googlebot repeatedly visiting URLs that should be returning 404s, that is a crawl budget leak. Log file analysis requires a tool such as Screaming Frog Log File Analyser or a custom setup, but for large sites it is the most precise diagnostic available — far more reliable than sampling from a crawler alone.
Site Crawlers
Tools such as Screaming Frog SEO Spider can be configured to flag pages returning 200 status codes with low word counts or specific content patterns (such as "page not found" in the title tag). This cross-referencing of status codes with content signals is the most practical way to surface soft 404s at scale without relying solely on Search Console.
The Right Fix for Each Error Type
The fixes are not interchangeable. Applying the wrong solution to the wrong error type can make the problem worse.
Fixing Genuine 404s
For URLs that no longer serve useful content and have no logical redirect destination: leave them as 404s. There is no SEO benefit to redirecting every dead URL to the homepage. Google understands 404s; a mass redirect to an irrelevant page is worse for users and sends poor signals.
Where a 404 URL had inbound links or was previously well-trafficked, implement a 301 redirect to the most relevant live page. Where no close equivalent exists, a 404 is the correct response. Do not create thin placeholder pages purely to avoid a 404 — that is how soft 404s are born.
Fixing Soft 404s
There are three legitimate resolutions, and the right one depends on whether the URL has any residual value:
- Return a proper 404 or 410 status code. If the page genuinely has no content and no future, configure the server to return a 404 (gone temporarily) or a 410 (gone permanently). A 410 tells Google it can de-index the URL faster than a standard 404.
- Redirect to a relevant live page. If the URL had inbound links or ranking history, a 301 redirect to the closest relevant live page recovers that equity while resolving the soft 404.
- Add substantive content. If the page should exist (a category page, a filtered results page), the fix is to ensure it always has meaningful content — or to use canonical tags to consolidate thin variants into a primary URL.

FAQ
Is a soft 404 worse than a 404 for SEO?
In most cases, yes — particularly at scale. A genuine 404 is an honest signal that Google processes and moves on from. A soft 404 misleads Google into treating a non-functional or empty page as live content, which wastes crawl budget, contributes to index bloat, and can depress the overall quality signals of your domain. A single soft 404 is unlikely to cause noticeable harm; hundreds or thousands of them on a large site is a material problem.
Will Google penalise my site for having soft 404s?
Google does not issue a manual penalty specifically for soft 404s. The damage is more structural: crawl budget is wasted on low-quality URLs, thin pages may dilute your site's overall quality signals, and link equity passed to soft 404 pages is poorly spent. The impact compounds over time rather than arriving as a single algorithmic event.
How quickly does Google remove a genuine 404 from its index?
There is no fixed timeline. Google re-crawls 404 URLs multiple times before removing them from the index — this process can take weeks to several months depending on the site's crawl frequency. You can expedite removal of specific URLs using the URL Removal Tool in Google Search Console, or by returning a 410 status code, which Google typically processes faster than a 404.
Can a page be flagged as a soft 404 even if it has some content?
Yes. Google's classification of a soft 404 is based on its assessment of content quality relative to user intent, not simply a word count threshold. A page returning a 200 status code with a single sentence, a "no results found" message, or heavily duplicated boilerplate may still be flagged as a soft 404 in Search Console. The fix in these cases is either to add substantive, unique content or to remove the page from Google's index via a noindex directive or a proper redirect.
What to Do This Week
Rather than auditing your entire site at once, start with the highest-leverage actions:
- Open Google Search Console → Pages → Why pages aren't indexed. Export the soft 404 list. If it runs to more than a few dozen URLs, prioritise by whether those URLs have inbound links (check via your backlink tool) or previously ranked for anything meaningful.
- Check your CMS's default 404 template behaviour. Ask your developer to confirm what HTTP status code the "page not found" template actually returns. Do this with a tool such as httpstatus.io — enter a URL you know doesn't exist on your site and verify the response code shown.
- Identify your highest-traffic filtered or faceted URLs. If your site uses URL parameters for filtering (colour, size, date range), check whether zero-result states return a 200 or are handled with a noindex tag. This is the single most common source of mass soft 404s on e-commerce and publisher sites.
- For genuine 404s with inbound links: export your dead pages from a crawler, cross-reference against your backlink profile, and implement 301 redirects for any URL with meaningful link equity pointing at it.
None of these steps require a site-wide rebuild. A focused half-day audit using Search Console and a status code checker will surface the majority of your soft 404 exposure — and give you a prioritised fix list your developer can work through systematically.
