A soft 404 error occurs when a web server returns a 200 OK status code for a page that lacks meaningful content or no longer exists. This misleads search engines, as they assume the page is a valid destination and continue attempting to crawl or index it. To resolve this issue, you must configure your server to return an explicit 404 (Not Found) or 410 (Gone) status code when a user or bot requests a URL that has been permanently removed or never existed.
Ignoring these errors creates a long-term drain on your site quality. Search bots have a finite capacity for how many pages they can visit on your domain within a specific timeframe. When a significant portion of that capacity is spent on non-existent content, your site’s ability to show new or updated information in search results is hampered. By ensuring your server communicates correctly, you help Google prioritize your active, high-value pages.
Why do soft 404s impact your SEO performance?
Search engines rely on HTTP status codes to interpret the state of a webpage. When a page serves a 200 status code, Google assumes the content is valuable and ready to be processed. If the page contains a message such as ‘Item Not Found’ or redirects the visitor to the homepage without a clear purpose, the engine wastes resources on non-existent content. This inefficiency consumes your crawl budget, which is the amount of time and effort Googlebot allocates to your site, potentially reducing the frequency at which crawlers visit your high-value pages.
Consider a large e-commerce site where thousands of seasonal product pages are deleted annually. If the server redirects every single one of these to the root domain, the search engine perceives the site as having thousands of duplicate homepages. This creates a cluttered index where the most relevant content becomes harder to locate, eventually causing a drop in organic search visibility for active products. Addressing these issues creates a cleaner, more reliable site structure that is easier for both users and crawlers to understand.
How to identify soft 404s using Google Search Console
The Indexing report in Google Search Console is the primary tool for monitoring these errors. It provides a dedicated section for pages that are excluded from the index, specifically tracking those categorized as ‘Not found (404)’ and ‘Soft 404’. If you find pages listed under the Soft 404 category, it indicates that Google’s systems have determined the content is insufficient or missing, despite the server claiming the page is a standard, healthy request.
To perform a thorough check, you should combine Search Console data with your internal server logs. Search Console provides the initial signal, but your server logs confirm the technical reality of the response code. If you notice a high volume of these errors, categorize them by URL patterns. Often, these errors happen across entire directories, such as an old tagging system or an archived collection that has been moved, allowing for a bulk fix rather than individual URL management.
- Navigate to the Indexing section in the sidebar of Search Console.
- Open the Page Indexing report to view the list of excluded pages.
- Filter the results by selecting the ‘Soft 404’ category to view specific URLs.
- Perform a URL Inspection on sample pages to confirm if they return a 200 OK code.
- Check your server access logs to see the exact status code returned for those specific URLs.
What are the common causes of these errors?
Soft 404 errors frequently arise from content management system (CMS) configurations or improper redirect handling. For example, some platforms are programmed to catch every broken URL and redirect the user back to the search results page or the homepage to improve user experience. While this keeps the user on the site, it sends an incorrect signal to search crawlers, telling them that the non-existent page is a legitimate destination.
Another common culprit is the use of JavaScript to display error messages. If your site uses a client-side script to render a ‘404 page’ layout while the server continues to send a 200 header, the search engine will ignore the visual error and index the page anyway. It is essential to ensure that the status code is sent at the server level, long before the browser renders the HTML or runs any scripts.
Manual data collection in the Search Console dashboard is restricted by interface constraints.

Common misconfigurations to watch for
- Redirecting large batches of deleted product pages to a generic category page.
- Displaying an empty template page that returns a 200 status code.
- Using client-side JavaScript to display error messages instead of server-side codes.
- Incorrectly mapping URLs that were recently migrated to a new site structure.
- Failing to remove internal links to pages that no longer serve a purpose.
How Alien Road applies this
At Alien Road, our process begins with a comprehensive site architecture review to identify high-traffic areas that might trigger soft 404s. We use server-side log analysis to confirm exactly what status code is being delivered to Googlebot. If a client manages a large inventory, we implement a systematic removal process for deprecated content. We often ensure that truly deleted pages serve a 410 Gone status, which acts as a stronger signal to Google that the content is permanently removed.
For example, in a typical engagement with a legacy retail site, we identified over 5,000 URLs that were returning 200 OK statuses despite having no content. By applying a bulk update to the server response headers, we allowed Google to clear these outdated URLs from the index. This action improved the site’s overall crawl efficiency, as search engines could then focus their resources on the active, high-converting product pages that were previously being ignored due to crawling delays. We monitor these changes for 30 days to ensure the index reflects the new, corrected status codes.
When should you use 404 versus 410 codes?
Distinguishing between a 404 and a 410 status code provides Google with more specific instructions. A 404 (Not Found) code implies that the page might return in the future or that the missing resource is a temporary issue. It is the standard response for a broken link or a removed page that is not expected to return.
A 410 (Gone) status code is more explicit; it tells search engines that the resource is intentionally removed and will not be coming back. This is highly beneficial for large sites undergoing significant restructuring. By using 410 codes, you encourage search engines to drop these URLs from their index faster. If you know for certain that a page is permanently gone, use the 410 status to clean up your site index faster than a standard 404 would.
Where to start this week
Begin your audit by exporting the ‘Soft 404’ report from Google Search Console into a spreadsheet. Group the URLs by directory to identify patterns, such as an entire category of products that were recently removed or a broken tagging system. Once you confirm the pattern, work with your developers to update the server response to return a 404 or 410 status code. By correcting these statuses, you allow Google to manage its index more effectively, ensuring your active content receives the attention it needs to rank.
