Meta Tag Previewer Guide

Reference for checking page titles, descriptions, canonical URLs, robots directives, Open Graph tags, and social preview metadata before publishing.

Quick answer

Use the Meta Tag Previewer to review a page title, meta description, canonical URL, robots directive, Open Graph title, description, URL, and image metadata before publishing.

What this tool does

The tool helps you inspect metadata in a predictable view. It is useful for content QA, launch checklists, migration reviews, and spotting stale copy before a page is submitted for indexing.

Supported input

  • Page title
  • Meta description
  • Canonical URL
  • Robots directive
  • Open Graph title, description, URL, and image
  • Twitter card metadata when relevant

Data handling and processing behavior

Processing is handled in the browser for this tool based on the current public implementation. Avoid entering sensitive unpublished URLs or campaign copy unless you have reviewed the implementation and your own data handling requirements.

Step-by-step use

  1. Paste or enter the title and description
  2. Add the canonical URL
  3. Check robots directives for accidental noindex or nofollow values
  4. Add Open Graph values for social preview checks
  5. Compare the preview with the actual page intent

Common errors

Title and H1 disagree. They do not need to be identical, but they should describe the same page.

Canonical points to staging. Always check that canonical URLs use the production host and final path.

Description is reused. Repeated descriptions make it harder for users and crawlers to understand what makes each page different.

Limits

The previewer does not guarantee how Google, Bing, social platforms, or AI answer engines will display a page. It only helps you inspect metadata you control.
