OGP Text Optimization — Improve Social Media Share Displays
Open Graph Protocol (OGP) controls how your web pages appear when shared on social media. Without proper configuration, titles get truncated and unintended descriptions appear, dramatically reducing click-through rates. This guide covers OGP text optimization and platform-specific display specifications.
Platform Display Specifications
| Platform | og:title Display | og:description Display | Image Size |
|---|---|---|---|
| X (Twitter) | ~70 chars | ~120 chars | 1200×628px |
| ~60 chars | ~80 chars | 1200×630px | |
| ~70 chars | ~100 chars | 1200×627px | |
| Slack | ~70 chars | ~150 chars | 1200×630px |
Design your og:title around Facebook's ~60 character limit to ensure proper display across all platforms.
Optimizing og:title
- Keep to 40–60 characters for universal display
- Omit the site name — use the space for article content
- Include numbers and specifics for higher CTR
- og:title can differ from the HTML title tag — optimize each for its context
Writing og:description
Keep og:description to 70–120 characters. Place the most important information in the first 40 characters so truncation doesn't lose meaning. Use Character Counter to verify lengths.
OGP Image Guidelines
- Size: 1200×630px (landscape) as the standard
- Text on images: limit to 5–10 words, minimum 40px font
- Keep text in the center-upper area — bottom may overlap with platform UI
- Ensure sufficient contrast between text and background
Debugging and Validation
Always verify OGP settings using platform debugging tools: Facebook Sharing Debugger, X Card Validator, and LinkedIn Post Inspector. If cached data persists, use the re-scrape function to fetch updated OGP information.
Common Mistakes
- Using identical og:title and HTML title — missing the opportunity to optimize for social context.
- Not setting og:image — platforms auto-select irrelevant images, hurting CTR.
Conclusion
Aim for 40–60 characters for og:title and 70–120 for og:description. Always verify with debugging tools before publishing. Use Character Counter to check your OGP text lengths.
