How to Validate Open Graph Metadata on Your Website

Open Graph (OG) tags control how your pages appear when shared on social platforms. Missing or incomplete tags often lead to low-quality previews, reduced click-through rates, and lost traffic. The LinkMagnet Open Graph validator makes it easy to audit and fix your metadata in minutes.

Why Open Graph tags matter

• Better previews: Correct titles, descriptions, and images make links look trustworthy and clickable.
• Consistent branding: Your site name, image, and description stay consistent across platforms.
• Higher engagement: Clear previews improve click-through rates and conversions.
• Fewer surprises: You avoid broken previews or missing images on launch day.

Use the Open Graph validator

1. Open the validator: https://linkmag.net/validator
2. Paste your URL and click Validate URL.
3. Review the Required, Optional, and Recommended sections.
4. Check the live previews for Facebook, X/Twitter, LinkedIn, Slack, and Discord.

The validator uses ogp.me as the source of truth. It highlights:

• Required tags like og:title, og:type, og:image, and og:url.
• Optional tags like og:description and og:site_name.
• Structured media tags (such as og:image:alt, og:image:width, and og:image:height) that improve accessibility and rendering.

Fix with LLM

The validator includes an LLM Report Export panel that generates a plain text report plus a ready-to-use prompt. This helps you hand the audit to an LLM with full context.

1. Open the LLM Report Export section.
2. Click Copy to clipboard (or Download .txt).
3. Paste it into your favorite LLM and ask it to suggest fixes.

Example prompt (auto-generated in the report):

These are the results of an Open Graph audit for our website. Please fix missing required tags, suggest values for missing optional tags, and highlight any structured media metadata that should be added. Use the report below as the single source of truth.

The report includes your URL, detected og:type, completion counts, and a list of every tag with descriptions and current values.

Common fixes

• Add og:description to improve preview text on social platforms.
• Use high-resolution og:image URLs and include og:image:alt for accessibility.
• Ensure og:url matches your canonical URL.
• Include og:site_name for consistent branding.

What to validate next

Once your OG tags are clean, validate a few key pages:

• Homepage
• Pricing or product pages
• Blog articles
• Landing pages and campaigns
