What does this tool check in my robots.txt?

This tool verifies that your robots.txt file exists, is accessible, and has valid directives. It checks user-agent rules, disallow/allow paths, and whether a sitemap URL is specified.

Can a misconfigured robots.txt hurt my SEO?

Yes. A robots.txt error like accidentally disallowing your entire site (Disallow: /) can prevent search engines from crawling any of your pages, effectively removing your site from search results.
