Google Search Console is not the only tool that can help you identify crawl errors. Other tools, such as Screaming Frog SEO Spider, Ahrefs Site Audit, and Moz Site Crawl, can provide a more comprehensive and detailed analysis of your site's crawlability and indexability. Screaming Frog SEO Spider is a desktop software that crawls your site and provides various reports and metrics, such as response codes, canonicals, redirects, meta tags, and more; you can use it to identify crawl errors like 404s, 500s, noindex, or robots.txt directives. Ahrefs Site Audit is a web-based tool that crawls your site and provides a health score and a list of issues and recommendations; it can be used to identify crawl errors such as broken links, duplicate content, orphan pages, or internal redirects. Moz Site Crawl is another web-based tool that crawls your site and provides a summary of issues and insights; it can help you spot crawl errors like missing titles, descriptions, or headings, thin content, or blocked resources.
