What Is A Crawl Error?
A Crawl Error is a problem that prevents a search engine crawler from accessing, fetching, or processing a web page or resource. The problem may come from a broken URL, server response, blocked instruction, redirect, or technical configuration. Crawl Errors can affect discovery and indexing, depending on the page and the cause.

Key Takeaways About Crawl Error
- Crawl Errors concern search engine access, not necessarily human visitor access.
- Review the affected URL and the technical cause before choosing a fix.
- A Crawl Error is not the same as a ranking decline.
How Crawl Error Works
A Crawl Error appears when a search engine crawler cannot complete a request for a page, file, or other resource. The crawler may meet a broken internal link, a server failure, a redirect chain, or an instruction that blocks access. The error describes the crawler's experience at that point in the visit.

Google Search Console can report affected URLs and group problems by their apparent cause. A technical review then checks the URL, response behaviour, internal links, sitemap references, and access rules. A page that loads for you can still present a crawl problem if crawler access differs from browser access. The correct response may involve repairing a link, changing a directive, restoring a resource, or confirming that the page should remain unavailable.
Expert Note
When we review Crawl Errors, we trace each affected URL to its source, response behaviour, and intended status. We then compare crawler access with internal links, sitemap entries, and indexation signals. Our team records whether the issue needs a fix, a redirect, or no action.
