What are Open Graph tags?
Open Graph (OG) tags are snippets of code that control how URLs are displayed when shared on social media. They were originally created by Facebook but are now used by LinkedIn, Pinterest, and many other platforms.
The most common tags include:
- og:title - The headline of your content.
- og:description - A brief summary of the page.
- og:image - The visual preview (thumbnail) shown in the feed.
- og:url - The canonical URL of the page.
Why use this Open Graph preview tool?
Optimizing your social sharing cards is a crucial part of technical SEO and brand visibility.
- Boost Click-Through Rates: Attractive, well-structured cards with high-quality images can significantly increase clicks from social feeds.
- Ensure Professionalism: Broken images or missing descriptions make your brand look unprofessional. Debugging them here prevents public errors.
- Verify Cross-Platform Look: Check how your content appears on both Facebook/LinkedIn standards and Twitter/X specific card formats.
How this Open Graph Preview Works
This tool sends a request to your URL and extracts the `og:image`, `og:title`, and `og:description` tags. It then reconstructs the exact visual card that users will see when you share the link on social platforms.
- Cache Busting: We fetch fresh data, helping you debug if social networks are showing old images.
- Dimension Check: We verify if your image aspect ratio is optimal (1.91:1) for large summary cards.
- Missing Tags: We check for fallback tags (like `twitter:image`) if standard OG tags are missing.
Why it Matters for GEO
Click-Through Rate
A link with a compelling image gets up to 300% more clicks than a naked URL. If your OG image is missing or cropped badly, you lose traffic.
Professionalism
When users share your link on Slack or Discord, a broken preview looks like spam. A valid card establishes trust immediately.
