About this tool
Audit social metadata blocks before publishing so shared links show the right title, description, and image across major platforms.
Open Graph Tag Checker is designed for launch QA, where social metadata often breaks because of template changes, missing image tags, or conflicting fields. It gives teams one focused pass for validating share-preview markup before campaigns go out.
- Parses Open Graph and Twitter meta tags from full HTML snippets or key-value lines.
- Flags missing required OG fields, duplicate properties, and invalid URL formats.
- Outputs a normalized meta tag block you can copy into templates or CMS head fields.
How to use OG Tag Checker
Paste the meta tag block or page head output, then review which Open Graph and Twitter fields were detected, what is missing, and which values should be normalized before release. Fix the source template or CMS fields, then run the page again to verify the final tag set.
When this tool is useful
- QA social metadata before publishing new blog posts, product pages, or landing pages.
- Validate CMS-generated head tags after template changes or plugin updates.
- Catch missing og:image or Twitter card fields before sharing links in campaigns.
Practical tips
- Keep og:url canonical and absolute so social previews map to one preferred page.
- Use consistent title and description intent across OG and Twitter fields unless you have a channel-specific reason.
- Host og:image on a stable HTTPS URL and avoid temporary asset links from draft environments.
Examples you can test
These examples show the kind of real input and reviewed output this tool is designed to support. Use them as a starting point before pasting your own production content, then compare the output with the destination system that will use the result. The goal is not only to produce a value, but to make the input assumptions, output format, and review step clear enough that the result can be trusted in a real workflow.

Example input
HTML containing og:title, og:description, og:image, and og:url
Expected output
Detected Open Graph tags and preview-related warnings
Useful before sharing a page in social feeds, chat apps, or campaign materials.
Detect a missing image tag
Example input
HTML with title and description but no og:image
Expected output
Missing image warning
Pages without social images often look unfinished when shared.
Validation checklist
Run through these checks before copying the result into a CMS, codebase, spreadsheet, campaign, support ticket, or production document. Small formatting differences, unit assumptions, hidden whitespace, and platform-specific rules are common sources of mistakes in quick browser tools, so the final review should happen in the same context where the output will be used.
- Check title, description, image, URL, and type together.
- Use an absolute, crawlable image URL for og:image.
- Re-test after deployment because social crawlers may cache old metadata.
Why people use this tool
