Complete Guide to Twitter Cards

What are Twitter Cards?

Twitter Cards (also called X Cards) are rich media attachments that transform plain URLs into engaging visual previews. When someone shares a link on Twitter/X, these cards display images, titles, descriptions, and other metadata, making content more attractive and clickable.

Benefits of Twitter Cards:

• 2-3x higher engagement rates
• Professional appearance in timeline
• Increased click-through rates
• Better content discoverability
• Enhanced brand visibility
• Mobile-optimized previews

Common Card Types:

• Summary Card: Title, description, thumbnail
• Summary Large Image: Large featured image
• App Card: Mobile app promotion
• Player Card: Video/audio content

twitter:image	og:image
twitter:url	og:url
