What the sitemap validator checks

Focused sitemap validation for technical SEO QA

Wranker focuses on the sitemap issues that can affect crawl discovery, indexation workflows, and technical handoff quality.

Use it during internal linking audits, content optimisation, technical SEO reviews, website migrations and content hub planning.

Fetch health

Sitemap fetch and XML status

Check whether the sitemap file is accessible, fetchable, and parseable as XML.

Sitemap structure

Index and child sitemap review

Review sitemap index files and child sitemap files to confirm they are reachable and returning valid responses.

URL quality

Status, redirect, and canonical checks

Find non-200 URLs, redirected sitemap URLs, and canonical mismatches inside listed sitemap entries.

Coverage gaps

Find crawlable URLs missing from sitemaps

Use spot crawl coverage to compare discovered URLs against sitemap URLs and surface important missing pages.

Why sitemap validation matters

Clean sitemaps create clearer discovery signals discovery signals

A sitemap does not guarantee indexing, but it helps search engines discover important URLs more efficiently. Broken, redirected, non-canonical, or outdated sitemap entries can make that discovery workflow harder to trust.

Keep sitemap URLs clean

Find broken, redirected, and non-canonical URLs before they create confusing discovery signals.

Improve crawl discovery

Make sure important indexable URLs are represented in sitemap files and ready for discovery workflows.

Support technical SEO QA

Validate sitemap fetch status, XML parsing, child sitemap files, sampled URL health, and coverage gaps.

Frequently asked questions

Sitemap validator FAQs

Straight answers about live URL checks, sitemap formats, redirects, canonicals, coverage, and technical SEO scope.

A Sitemap Validator checks whether a sitemap can be fetched and parsed, then reviews listed URLs for technical issues such as non-200 responses, redirects, and canonical mismatches.

Yes. The tool is designed to check live sitemap URLs and live site URLs. It should not be described as checking staging, private, or password-protected URLs unless that functionality is confirmed.

The UI indicates support for sitemap index files, .xml, and .xml.gz sitemap files.

Auto-detect mode starts from a site URL and tries common sitemap paths such as /sitemap.xml, /sitemap_index.xml, /sitemap.xml.gz, and /sitemap-index.xml.

Sitemap URLs should usually point to clean, accessible pages. Non-200 URLs can create poor discovery signals and should be reviewed.

Usually, no. Sitemaps should generally include final canonical URLs rather than redirected URLs.

Non-canonical means the sitemap URL and the page’s detected canonical URL do not match.

Sitemap coverage compares discovered or crawled URLs with sitemap entries to find important crawlable pages missing from the sitemap.

Yes. You can export CSV data or use Download Report to share findings with developers, clients, or SEO reviewers.

No. This tool focuses on sitemap validation and coverage. For full crawl-based analysis, use Wranker’s Site Audit Tool.
