Common use cases

Check pasted viewport meta tags while reviewing responsive templates, copied head snippets, or migration exports before publishing.

Use Viewport Meta Checker during a pasted-input SEO QA pass before publishing or handing off a page. It helps review copied metadata, snippets, headings, social tags, or canonical signals without crawling a live URL.

How to use it

  1. Paste a viewport meta tag, HTML head snippet, or copied page-source fragment.
  2. Review the number of viewport tags, extracted content values, and responsive/accessibility warnings.
  3. Copy the viewport values into QA notes or compare the snippet with adjacent HTML SEO checks.

Example workflow

Paste the relevant title, description, tag block, heading outline, or canonical markup from your draft page. Review the warnings and preview output, make edits in your CMS or document, then recheck the same pasted input before publishing.
