FAQPage Schema
How do I validate sitemap.xml and robots.txt files against specifications?ā–¼

Validate sitemap.xml and robots.txt by running the checker against your site or local files—it enforces structural requirements like correct root elements, required fields, absolute URLs, and encoding to surface compliance issues with actionable fixes.

What web resource files can I audit for SEO and security compliance?ā–¼

Audit sitemap.xml, robots.txt, llms.txt, llms-full.txt, and security.txt files. The checker validates each against official specifications, reports severity-based issues, and outputs both machine-readable JSON and human-readable formats for quick remediation.

Can I run web resource validation on a live site or only local files?ā–¼

Run validation on both live sites and local copies. Pass a URL like https://example.com or a local path like ./public to check resources in place, then review JSON or human-readable reports to identify and fix configuration errors.

Why does security.txt validation matter for web compliance?ā–¼

Security.txt helps disclose security policies and contact information to researchers. Validation ensures it follows specification requirements—correct placement, required fields, and format—reducing missed security disclosures and improving incident response readiness.

What happens if my robots.txt or sitemap.xml doesn't meet specification requirements?ā–¼

The checker detects structural violations—missing elements, invalid URLs, encoding problems, and size limit breaches—and returns severity-flagged issues with concrete guidance so you fix indexing, crawling, and security risks before they impact SEO or accessibility.

Do I need any dependencies or setup to run web resource validation?ā–¼

No dependencies required. Run npx web-resource-checker against a live domain or local directory to immediately validate resources and receive structured reports identifying compliance gaps and fixes.
