How to Identify and Audit Soft 404 Errors on Your Website

From an SEO perspective, few things are as frustrating as a “Soft 404” error. Unlike a standard 404 error, where a server explicitly states that a page doesn’t exist, a Soft 404 occurs when a page tells users it is missing but returns a successful 200 OK status code to search crawlers. Because the server claims the page is fine, Google continues to index and crawl it, wasting your website’s crawl budget and degrading your search visibility. In this technical SEO guide, we will explore what Soft 404 errors are, why they are harmful, and how to identify and resolve them in bulk.

What is a Soft 404 Error?

An explanation of the discrepancy between the visual content (e.g., “Page not found” or empty pages) and the server’s HTTP header response (200 OK).

Why Soft 404s Hurt Your SEO Strategy

• Crawl Budget Waste: Search bots waste time reading thin, broken pages instead of indexing high-value ones.
• Diluted User Signals: High bounce rates on useless pages tell search engines your site is low quality.
• Indexation Bloat: Keeping low-quality, empty pages in the Google index.

Common Causes of Soft 404 Errors

• Thin content pages or blank pages with no text.
• E-commerce category pages with zero products in stock.
• Missing files redirecting users to the homepage instead of a proper error page.
• JavaScript errors preventing page content from rendering for search bots.

How to Find and Audit Soft 404s in Bulk

1. Google Search Console (GSC): Using the Page Indexing report to find pages labeled as “Soft 404”.
2. Bulk URL Status Checkers: Auditing page content and header combinations across lists of URLs.
3. Crawl Logs: Checking server access logs to spot search bot activity.

Step-by-Step Guide to Fixing Soft 404 Errors

• Returning a true 404 Not Found or 410 Gone header code.
• Redirecting permanently deleted pages to a highly relevant page with a 301 redirect.
• Adding high-quality content or items back to thin pages.
