Frequently Asked Questions

What are Open Graph tags?

Open Graph (OG) tags are HTML meta tags that control how your links appear when shared on Facebook, Twitter, LinkedIn, and other platforms.

Why isn't my link preview updating?

Social platforms cache OG data. Use Facebook's Sharing Debugger or Twitter's Card Validator to force a refresh after updating your tags.

What size should an OG image be?

The recommended OG image size is 1200×630 pixels. This ensures proper display across Facebook, Twitter, LinkedIn, and WhatsApp.
