Chapter 4: Technical SEO
Crawl errors are issues that occur when search engine bots, like Googlebot, attempt to crawl and index a website's content, but are unable to do so. These errors can negatively impact a website's visibility and organic ranking in search engine results pages (SERPs).
There are two main types of crawl errors: site errors and URL errors. Site errors affect the entire website, while URL errors are specific to individual pages. Common crawl errors include server errors, DNS errors, and URL errors like 404 errors, soft 404 errors, and 301 redirects.
Crawl errors can harm a website's SEO performance by preventing search engines from indexing important pages and content. It is important for website owners to monitor and fix crawl errors to ensure that their site is easily accessible to search engine bots and can be properly indexed. This can be done by regularly checking the website's crawl error report in tools like Google Search Console and addressing any issues that are found.
