Sitemap Validator

このツールが使われる理由

Sitemap Validator is useful when you need to check whether a sitemap file is structurally sound before shipping it to production or submitting it in Search Console.

• Check a sitemap.xml file before a launch, migration, or technical handoff.
• Validate sitemap indexes and individual sitemap files from CMS or build output.
• Spot invalid URLs, missing tags, and format mistakes before search engines crawl the file.

使い方

1. 1Paste the sitemap XML or sitemap index content into the validator.
2. 2Review the detected issues, warnings, and supported entries.
3. 3Fix the source file, then re-run the validation before publishing or submission.

Best practices

• Validate the sitemap after template changes, migration scripts, or build pipeline edits.
• Keep only canonical, indexable URLs in the file so the sitemap stays trustworthy.
• Review sitemap indexes and child files together when a site uses multiple sitemap outputs.
• Re-check the file after correcting one issue because XML and URL errors often appear in clusters.

Common mistakes to avoid

• Do not submit a sitemap that still contains staging, broken, or redirected URLs.
• Do not assume your CMS output is valid without checking the final XML.
• Do not leave malformed loc entries or wrong protocols in a production sitemap.
• Do not treat a valid sitemap as a substitute for strong internal linking or crawlable architecture.
