Syntax & Fallback Comparison
Twitter Card vs Open Graph: Key Differences & Fallback Behavior
While both tag systems control link previews, Open Graph (og:) is universal across platforms, whereas Twitter Cards (twitter:) are specific to X.com.
Key Technical Takeaways
- ✓Syntax Difference: Open Graph uses property="og:...", Twitter Cards use name="twitter:...".
- ✓Fallback Priority: X reads twitter: tags first, then og: tags, then HTML <title>.
- ✓Minimum Required: Including <meta name="twitter:card" content="summary_large_image"> is enough if full OG tags exist.
Implementation Example
<!-- Open Graph (Universal) -->
<meta property="og:title" content="Title for All Platforms" />
<!-- Twitter Card (X.com Specific) -->
<meta name="twitter:card" content="summary_large_image" />
<meta name="twitter:title" content="Custom Title for X" />
