Imagine walking down a busy street and seeing a store with a beautiful window display. You’re curious, so you pull on the door only to find it locked. The store exists, the products are inside, but you can’t get in. Most people wouldn’t try again. They’d keep walking and go somewhere else.
That’s exactly how search engines experience a website with crawl errors. Your content may exist, but if Google or Bing can’t “enter,” it might as well be invisible. In SEO, invisibility means lost rankings, missed traffic, and fewer conversions.
What Are Crawl Errors?
Crawl errors happen when a search engine’s bot, also known as a crawler or spider, tries to access a page on your site but fails. Crawlers follow links, scan sitemaps, and index pages so they can appear in search results. If the crawler can’t reach a page, it gets flagged as a crawl error.
In short: A crawl error is a failure in communication between your website and a search engine.
These errors signal that something is blocking or disrupting access. Sometimes it’s a temporary glitch, like a server timeout, while other times it’s structural, like a broken link or misconfigured setting. Understanding this distinction helps prioritize which errors to fix first, ensuring crawlers spend time on valuable pages instead of dead ends.
