A soft 404 occurs when a web page returns an HTTP 200 status code instead of 404, but contains no useful content or is essentially empty.

01What it is and how it works
When a server returns HTTP 200 OK, browsers and search engines assume the page has valid content. A soft 404 happens when the page loads but contains only a message like 'Page not found' or 'This page is under construction' without proper 404 headers. Google's algorithms analyze the page content, user experience signals, and internal linking patterns to identify these false positives. The search engine may then apply soft 404 detection, removing the page from search results or treating it as a soft error rather than a valid page.
A soft 404 is when a website shows a page that looks like it should have content, but actually has none. The server says the page is fine (status 200), but there's nothing there. Google can figure this out and may ignore the page as if it were gone.
02What to do about it
If you discover a soft 404 on your site, you need to take immediate corrective action. First, determine whether the page should exist and have content. If it's a temporary page that should have content later, add a noindex tag until the page is ready. If the page is genuinely gone, implement a proper 404 status code or redirect it to a relevant existing page. For pages that are under construction, create a holding page with useful links to your main site sections. Monitor Google Search Console for soft 404 errors and fix them within a few weeks to prevent ranking damage.
- Implement proper 404 status codes for genuinely missing pages
- Add noindex tags to temporary placeholder pages
- Create useful holding pages with site navigation links
- Set up 301 redirects to relevant existing content when appropriate
- Monitor Google Search Console for soft 404 error reports
03How it is measured or noticed
The most reliable way to identify soft 404s is through Google Search Console's Coverage report, which specifically flags these errors under 'Error' type. You can also manually check by viewing the page source and looking for text like 'not found' or 'under construction' while the HTTP status remains 200. Browser developer tools show the actual status codes being returned. Third-party SEO tools like Screaming Frog or Ahrefs also detect soft 404 patterns by analyzing page content and HTTP responses together. Regular site crawls will reveal pages with minimal or no content that return 200 status codes.
04Common mistakes
Many site owners accidentally create soft 404s through common oversights. Using generic templates without proper error handling is a frequent cause. Another mistake is implementing JavaScript-based error messages without updating the HTTP status code. Some developers create placeholder pages that look complete but contain little actual content. Redirecting all missing pages to the homepage instead of using proper 404s creates poor user experience. Failing to update server configurations when removing pages is another common error that leads to soft 404 situations.
- Using generic templates without proper error status codes
- Implementing JavaScript error messages without HTTP 404 headers
- Creating placeholder pages with minimal actual content
- Redirecting all missing pages to homepage instead of proper 404s
- Not updating server configs when removing or changing pages
05Limits
Soft 404 detection has specific boundaries that marketers should understand. Google's algorithms use multiple signals to identify soft 404s, so a single indicator rarely triggers detection. Pages with substantial content, even if they're under construction, typically won't be flagged as soft 404s. The concept applies primarily to Google's interpretation and may differ for other search engines. Temporary maintenance pages with useful navigation and clear messaging usually avoid soft 404 classification. Understanding these limits helps prevent over-correction of pages that are genuinely valid but incomplete.
06Worked example
Consider an e-commerce site that removes a product page but leaves the URL active. The page loads with a message 'This product has been discontinued' but returns HTTP 200. Google's crawler sees the page has no product information, minimal content, and the 'discontinued' message. After analyzing user engagement metrics and content quality, Google's soft 404 detection flags this as a soft error. The page disappears from search results, and the site loses traffic for that product. The correct approach would be to implement a 404 status or redirect to similar products with a 301 redirect, preserving user experience and search visibility.
"A page that returns HTTP 200 but contains only a 'Page not found' message is considered a soft 404 error by Google's algorithms. These pages may be removed from search results as if they were permanently unavailable."

Frequently asked questions
How is a soft 404 different from a regular 404 error?
A regular 404 returns the correct HTTP 404 status code, signaling to search engines that the page does not exist. A soft 404 returns HTTP 200 OK, misleading search engines into thinking the page is valid when it has no useful content.
Should I fix a soft 404, and what depends on that decision?
Yes, you should fix it if the page is meant to be gone or empty. Leaving it can waste crawl budget and prevent search engines from properly indexing your site.
How does Google detect a soft 404?
Google uses automated systems to analyze page content and HTTP status codes. When it detects a mismatch, such as a 200 status with thin or no content, it flags the page as a soft 404.
Where can I find soft 404 errors on my site?
You can find them in Google Search Console under the Coverage report, which lists soft 404s as a specific error type. Other tools like Screaming Frog or Sitebulb can also detect them during crawls.
What common mistakes cause soft 404s?
Soft 404s often occur when a server returns 200 OK for missing pages, or when custom error pages are misconfigured. They can also happen when redirects are removed but the original URL still serves a blank or minimal page.
What happens if I ignore a soft 404?
Ignoring soft 404s can lead to poor user experience and inefficient crawling by search engines. Over time, this may impact your site's indexability and search performance.
Asked out loud
spoken, not typedThe same term in the words somebody uses speaking to an assistant rather than typing into a box — written from the situation, which is why each one carries the situation it came from.
It depends on whether the page is supposed to exist. If it's meant to be gone, returning a 200 status tells search engines the page is valid, which can cause indexing issues.
Usually, the page returns a 200 OK status but has little or no real content. Google treats this as a soft 404 because the page isn't providing value to users.
You should return a proper 404 or 410 status code so search engines know the page is gone. Leaving it as a 200 with no content creates a soft 404 and wastes crawl resources.
