SEO Metadata Validator

Scan every public URL in your sitemap and validate title tags, meta descriptions, and canonical tags — with duplicate detection, CSV export, and copy-ready AI fix prompts.

We read your sitemap.xml, then check the title, meta description, canonical, H1, and social tags on every URL it lists.

What gets checked on every URL

  • Title tag present, 30–60 characters, unique across the site
  • Meta description present, 70–160 characters, unique across the site
  • Canonical tag present, absolute, self-referencing, and only one per page
  • Exactly one H1, plus og:title and og:description for link previews
  • No accidental noindex on pages listed in your sitemap

Pro tips

One title per page

Duplicate titles make Google pick a winner and bury the rest.

Canonicals point at themselves

A canonical aimed at another URL quietly removes the page from search.

30–60 and 70–160

Title and description character ranges that survive Google's truncation.

Fix the reds first

Missing tags and wrong canonicals cost rankings; length warnings only cost clicks.

Frequently asked questions

A canonical tag tells Google which URL is the real version of a page. If it points at another URL, Google may index that one instead and drop this page from search. Every page should normally point its canonical at itself.
