Validation

The validation panel is a powerful tool to check the correctness of website pages.
It can validate:

• HTML pages:
  Fast and essential, the built-in HTML validator doesn't bother with trivial validation errors which have no meaningful impact, and restrict its focus reporting only the worst validation errors that could impact rendering or SEO performance.
  It doesn't use external services and thus is extremely fast and efficient.
• XML Sitemaps:
  We believe this to be the most complete and fastest XML Sitemap validator on earth. That says it all.
  XML Sitemaps errors tend to impair your SEO effort, so we equipped this built-in validation engine both with rules to validate basic XML schema violation and - most importantly - rules to validate the Sitemap protocol.
