Frequently Asked Questions

Everything you need to know about Open Graph images and social media optimization in 2025.

What is an Open Graph image and why is it important?

An Open Graph image is the preview image that appears when your URL is shared on social media platforms like Facebook, Twitter, LinkedIn, Slack, and Discord. It's crucial for engagement - posts with images get 2.3x more engagement than text-only posts. A well-optimized OG image can significantly increase click-through rates.

What are the optimal Open Graph image dimensions for 2025?

The universal standard is 1200x630px (1.91:1 aspect ratio) which works across Facebook, LinkedIn, Twitter, Slack, and Discord. Twitter/X also accepts 1200x628px. For best results, always use this size with high-quality images under 5MB (ideally compressed to under 300KB).

Why do platforms cache my OG images and how can I refresh them?

Platforms cache OG images to improve performance. Slack caches for ~30 minutes, Facebook and LinkedIn cache indefinitely until manually refreshed. To force a refresh: use Facebook's Sharing Debugger, LinkedIn's Post Inspector, or Twitter's Card Validator. Adding a query parameter like "?v=2" to your image URL can bypass caches.

What's the difference between og:image and twitter:image?

og:image is the universal Open Graph tag used by Facebook, LinkedIn, Slack, Discord, and others. twitter:image is Twitter-specific. Twitter will fall back to og:image if twitter:image is missing, so you only need twitter:image if you want a different image specifically for Twitter/X.

How do I validate my Open Graph tags are working correctly?

Use this tool to preview how your URL appears across platforms! You can also use platform-specific validators: Facebook Sharing Debugger, Twitter Card Validator, LinkedIn Post Inspector. Make sure OG tags are in your initial HTML (not loaded via JavaScript) as crawlers don't execute JS.

What common mistakes should I avoid with OG images?

Common pitfalls: images too small (min 200x200px), wrong aspect ratio, file size over 5MB, relative URLs instead of absolute, missing og:image:width/height tags, images loaded via JavaScript, too much text overlay (Facebook may reject >20%), and forgetting that Discord supports up to 15MB while others cap at 5MB.
