Common Soft 404 Errors: How to Find and Fix Them
Soft 404 errors are one of the most common yet overlooked technical SEO issues. They can silently hurt your site’s performance without you even realizing it. In this guide, we’ll cover everything you need to know about soft 404s.
What Are Soft 404 Errors?
A soft 404 error happens when a page:
- Returns a 200 OK status code (indicating the page exists)
- But displays content saying the page is missing or not found
- Essentially acts like a 404 error without the proper status code
This is confusing for both users and search engines, as the server says everything is fine while the content says otherwise.
Why Soft 404s Hurt Your SEO
Wasted Crawl Budget
Search engines allocate a certain amount of resources to crawl your site:
- Wasted resources: Crawlers spend time on pages that don’t exist
- Missed opportunities: Legitimate pages may not get crawled
- Lower efficiency: Your crawl budget is used inefficiently
Confused Search Engines
Soft 404s send mixed signals to search engines:
- Mixed messages: Status code says OK, content says missing
- Indexing issues: Search engines may not know how to treat the page
- Ranking impact: Can negatively affect your site’s overall authority
Poor User Experience
Users get frustrated when they encounter soft 404s:
- Confusing experience: Users don’t understand what’s wrong
- Higher bounce rates: Users leave your site immediately
- Lost trust: Users may not return to your site
Common Causes of Soft 404s
Missing Content Templates
- Empty category pages: Category pages with no products or posts
- Broken search results: Search pages that show no results
- Removed content pages: Pages that were deleted but not properly redirected
Misconfigured CMS Settings
- Incorrect error handling: CMS shows content instead of 404 status
- Template issues: Error pages use wrong status codes
- Plugin conflicts: SEO plugins causing status code issues
Broken Redirects
- Redirect chains: Multiple redirects leading to issues
- Redirect loops: Pages redirecting to each other infinitely
- Redirecting to missing pages: Redirecting to another missing page
