Frequently Asked Questions

What are 404 crawl errors and how do they affect SEO?

A 404 crawl error occurs when a search engine bot tries to access a URL on your site that no longer exists or returns a "Not Found" response. While occasional 404s are normal, excessive crawl errors waste your crawl budget and can signal to search engines that your site is poorly maintained, potentially hurting your overall search visibility and rankings.

How should I fix 404 crawl errors?

The best fix depends on the situation. If the content has moved to a new URL, set up a 301 redirect from the old URL to the new one. If the content no longer exists and has no suitable replacement, return a proper 404 or 410 status code and create a helpful custom 404 page that guides visitors to relevant content on your site.

What is the difference between a 404 and a 410 status code?

A 404 status code means the page was not found, but it may return in the future, so search engines will periodically revisit the URL. A 410 status code indicates the page has been permanently removed and will never return, prompting search engines to remove it from their index faster. Use 410 for content you have intentionally and permanently deleted.
