What Are Crawl Errors in SEO?

Crawl errors occur when search engine bots (like Googlebot) attempt to crawl a page on your website but fail to do so.

There are two main categories of crawl errors:

  1. Site-level crawl errors – Prevent Googlebot from crawling your entire website (e.g., DNS errors, server connectivity issues).
  2. URL-level crawl errors – Prevent crawlers from accessing specific pages (e.g., 404 errors, redirect loops, robots.txt blocking).

If crawl errors are not fixed, Google may deindex important pages, harming your SEO performance.

Types of Crawl Errors (and How They Affect SEO)

Here are the most common crawl errors you’ll see in Google Search Console (GSC) and how they impact your SEO:

1. DNS Errors

  • Happen when Googlebot cannot communicate with your DNS server.
  • Causes: DNS timeout, server misconfiguration.
  • SEO Impact: Google won’t crawl your site, leading to indexing issues.

2. Server Errors (5xx)

  • Happen when your server doesn’t return a proper response.
  • Causes: Overloaded server, misconfigured hosting.
  • SEO Impact: Crawl budget waste, pages drop from the index.

3. 404 Errors (Not Found)

  • Occur when a page doesn’t exist.
  • Causes: Broken links, deleted content, wrong URLs.
  • SEO Impact: Poor user experience, wasted crawl budget.

4. Soft 404 Errors

  • Page returns a “200 OK” status but actually shows a “Not Found” message.
  • Causes: Thin content pages, poor redirects.
  • SEO Impact: Google may ignore such pages.

5. Redirect Errors (301/302)

  • Happen when redirects form a loop or lead to broken pages.
  • Causes: Incorrect redirect chains.
  • SEO Impact: Link equity loss, crawl inefficiency.

6. Robots.txt Errors

  • Occur when important pages are blocked from crawling.
  • Causes: Misconfigured robots.txt file.
  • SEO Impact: Google can’t access and index blocked pages.

7. Sitemap Errors

  • Errors inside your submitted XML sitemap.
  • Causes: Outdated or incorrect URLs.
  • SEO Impact: Google wastes crawl budget on invalid URLs.

How Crawl Errors Affect SEO?

  • Indexing Problems – If crawlers can’t access a page, it won’t appear in search results.
  • Crawl Budget Wastage – Google allocates limited crawl resources; errors waste them.
  • Reduced Rankings – Broken links and server issues hurt user experience and SEO.
  • Local SEO Impact – Crawl issues can prevent Google Business Profile (GBP) landing pages from ranking locally.
  • Ecommerce Impact – Product pages with crawl errors won’t be indexed, causing sales loss.

How to Identify Crawl Errors?

Use these tools to detect crawl errors quickly:

  1. Google Search Console (Crawl Stats & Indexing Report)
    • Shows crawl errors like server issues, 404s, and blocked resources.
  2. Screaming Frog SEO Spider
    • Identifies redirect loops, broken links, and duplicate pages.
  3. Ahrefs Site Audit / SEMrush Site Audit
    • Provides crawl error reports with SEO recommendations.
  4. Log File Analysis
    • Helps understand how Googlebot crawls your website.
