Meta / Open Graph / Twitter Card Checker & Generator

Four metadata examples

1. Product landing page: Generate a unique title, a concise factual description, a canonical URL for the actual product page and a representative social image. Review the output as text before adding it to the document head.
2. Blog article: Paste the existing HTML head and check for duplicate title or description elements. Keep the article's canonical URL on the article, rather than replacing it with the site's homepage.
3. Multilingual page: Give each language URL its own title, description and canonical that reflect that page. Canonicals and hreflang serve different purposes; this generator does not build a full hreflang cluster.
4. Social sharing: Generate Open Graph and Twitter/X card tags with a publicly accessible image URL. The image is not fetched or verified by this local tool, so test its availability separately.

Common mistakes and fixes

Do not use a relative canonical such as /products/1 when the form requests an absolute URL. Do not put generated tags into the visible body: place them in the document <head>. Avoid identical titles across unrelated pages and avoid claims the visible content cannot support. Search engines and social platforms may rewrite or ignore metadata; generated markup does not guarantee a particular preview. Inspect the actual served HTML after deployment, including any CMS-injected duplicate tags.

Review workflow: Check the source head, fill real page facts, copy the escaped output, deploy to a test URL and validate with platform-specific preview tools. For canonical guidance consult Google Search Central.
