Soft 404
CrawlingA soft 404 is a page that appears to work, but does not actually provide useful content. The server responds as if everything is fine, although the user or bot finds an empty, wrong or error-like page.
What means Soft 404
Soft 404: A soft 404 appears when a URL returns a valid response, usually 200, but the content shows that there is nothing useful. For a search engine, it is a confusing signal: technically the page loads, but in practice it should not be treated as a valid URL.

It matters because it consumes crawl resources and pollutes the site reading. If there are many pages like this, bots can waste time on low-value URLs and take longer to find the pages that deserve attention.
- Check that non-existing pages return a real 404 or 410 status.
- Avoid empty pages that respond with status code 200.
- Review internal results, deleted listings and old URLs.
- Differentiate a page without stock or content from a page that truly does not exist.
Common errors
