Soft 404 errors represent a discrepancy between the server response and the content intent, where a page returns a 200 OK status despite being empty or irrelevant. Detecting these issues requires a detailed analysis of crawl statistics data within Yandex Webmaster to ensure that the search engine index remains clean and efficient. Resolving these errors prevents the waste of crawl budget and helps maintain the ranking of valid pages by removing dead ends from the site structure.
What defines a soft 404 error in Yandex search?
A soft 404 is not an official HTTP response code but a classification used by search engines to describe a page that should be a 404 but is not. When a user or a bot requests a page that does not exist, the server should ideally return a 404 (Not Found) or 410 (Gone) status code. However, many servers are configured to send a 200 OK status while displaying a custom error message to the visitor. This tells the search engine that the page is a valid piece of content worth indexing, even if it contains no useful information.
Yandex identifies these pages by evaluating the content density and common error patterns. If a page has very little text or contains phrases like ‘product not found’ or ’empty category’ while returning a success code, it is flagged. These pages occupy space in the index and can dilute the authority of your actual content. For a large site, having thousands of these URLs can significantly slow down the discovery of new, high-quality pages.
A soft 404 is essentially a lie told by your server to the search bot. While it might look good to a user, it forces the crawler to process empty data as if it were a key landing page, which is a major efficiency killer.

How does crawl statistics data reveal hidden errors?
The Crawl Statistics section in Yandex Webmaster provides a log of every time the bot visits your site. It lists the URL, the date of the visit, and the HTTP status code received. By filtering this data, you can spot anomalies where URLs that you know are deleted or expired are still showing a 200 OK status. This report is the first place to look when you notice a high number of pages in the index that do not correspond to your actual product or post list.
Analyzing these statistics allows you to see the frequency of visits to these problematic URLs. If the bot is returning to empty pages daily, it is spending less time on your new blog posts or updated product listings. This data is vital for diagnosing why certain parts of your site are not being indexed as quickly as expected. It provides a clear view of how the bot perceives your site structure compared to your intended sitemap.
Why are soft 404 errors harmful for SEO performance?
The primary danger of soft 404s is the waste of crawl budget. Every search engine allocates a specific amount of resources to crawl a website based on its size, authority, and update frequency. When the bot spends that budget on pages that do not exist, it may miss important updates on pages that do. This leads to delayed indexing for new content and slower updates for price changes or stock availability in search results.
Secondly, these errors negatively impact user experience. If a user clicks a search result expecting a specific product but lands on a page that says ‘Nothing found’ despite the browser indicating a successful load, they are likely to leave immediately. This high bounce rate signals to Yandex that the page is not meeting user intent, which can eventually lower the overall trust score of your domain.
- Crawl budget waste on non-existent content
- Dilution of site authority with thin pages
- Increased bounce rates from frustrated users
- Delayed indexing of new or updated pages
- Confusion in search engine reporting and analytics
How Alien Road applies crawl statistics data analysis
At Alien Road, we treat crawl statistics as the foundation of technical health. Our process begins with a discovery phase where we export the last 90 days of crawl data from Yandex Webmaster. We then cross-reference this list with the client’s current database of active URLs. For example, in a typical engagement for a Shopify store with 10,000 products, we might find that 1,500 URLs are being crawled despite the products being discontinued months ago.
We then look for patterns in the URL structure. Often, soft 404s are generated by faceted navigation filters that lead to empty results. We work with the development team to ensure these pages return a proper 404 header. Once the fixes are deployed, we use the IndexNow API to notify Yandex immediately of the changes. This proactive reporting ensures that the search engine doesn’t have to wait for the next natural crawl to see the corrected status codes.
Our team monitors the ‘Excluded Pages’ report in Yandex Webmaster to confirm that the soft 404 labels are moving into the ‘HTTP Status: 404’ category. This shift indicates that the bot now understands these pages are gone, allowing it to focus its energy on the remaining high-value pages. This detailed monitoring is a key part of our monthly performance reviews for clients in Istanbul and beyond.
What are the common causes of soft 404s on e-commerce sites?
E-commerce platforms are particularly prone to these errors due to the dynamic nature of their inventory. When a product is sold out and the page is removed, the CMS might default to a generic category page or a search results page without changing the server response code. This is especially common with automated inventory systems that do not communicate directly with the SEO settings of the website.
- Discontinued products that redirect to the homepage with a 200 code
- Empty search result pages on the site’s internal search engine
- Expired promotional or seasonal landing pages
- Filter combinations that yield zero results
- Technical bugs in the CMS that handle missing URLs incorrectly
Using IndexNow is one of the most reliable ways to clear soft 404 errors. Instead of waiting for a crawl, you tell the engine exactly which URLs have changed status, speeding up the cleanup of your index.

How to fix soft 404 errors effectively?
The most effective way to resolve a soft 404 is to return a true 404 (Not Found) or 410 (Gone) HTTP status code. A 404 is appropriate for pages that are simply missing, while a 410 tells the search engine that the page is permanently removed and will not return. This signal is strong and tells Yandex to remove the URL from its index as soon as possible. You should also update your sitemap to ensure these URLs are no longer listed.
If the missing page has a direct equivalent, a 301 redirect is a better choice. For instance, if you have replaced an old model of a laptop with a newer version, redirecting the old URL to the new one preserves the link equity and guides the user to a relevant alternative. However, avoid redirecting all missing pages to your homepage, as Yandex may still classify these as soft 404s if the content is not relevant to the original request.
Where to start this week
Start by logging into Yandex Webmaster and navigating to the Indexing section to find your crawl statistics data. Look for any URL that returns a 200 OK status but is not part of your current marketing strategy or product list. Identifying these early is the first step toward a healthier site structure. Also, check your ‘Excluded Pages’ report specifically for the ‘Soft 404’ label to see which pages Yandex has already flagged.
Once you have a list of problematic URLs, work with your technical team to adjust the server headers. Ensure that your custom error page actually sends a 404 status code. Finally, submit your updated XML sitemap and use the IndexNow tool to trigger a re-crawl of the affected areas. Following these steps will lead to a more efficient indexing process and better visibility for your key pages.
