Crawl errors are issues reported by search engines as they crawl your website.Almost everything the search engine knows about your website, it learns via a program called a “spider” which it uses to scan or “crawl” your website. As this is a fundamental mechanism for search engines to interact with your site, we consider them important enough to check regularly. There are a number of different types of crawl errors and some are reasonably benign, while others are more serious issues.
