Open Graph (OG) images are the visual preview cards that appear when you share a URL on social media platforms like Twitter, LinkedIn, Facebook, and Discord. They typically display a title, description, and visual elements that make your content stand out in feeds. The recommended size is 1200×630 pixels.

What is an OG Image?

Open Graph (OG) images are the visual preview cards that appear when a URL is shared on social media platforms. Defined by the Open Graph Protocol, these images help content stand out in crowded social feeds by providing a visual summary of the linked page.

Key Benefits of OG Images

Increased Click-through Rates: Posts with custom images receive 2-3x more engagement than those without.
Brand Recognition: Consistent visual style builds recognition across platforms.
Professional Appearance: Custom images look more credible than auto-generated previews.
SEO Value: Rich previews can improve search appearance in Google and other engines.
