Twitter Card Meta Tags
Customize Twitter link previews with card meta tags.
Why a Separate Standard?
Twitter (X) defined its own preview-card protocol before OpenGraph existed and still maintains it. While modern Twitter falls back to OG tags when twitter:* tags are missing, declaring twitter:card explicitly gives the most predictable card layout.
twitter:card Types
Four card types: summary (small thumbnail next to title/description), summary_large_image (full-width hero), app (mobile app install), and player (embedded video or audio). Choose summary_large_image for content-heavy articles.
