Definition
A Twitter Card is a set of metadata fields that define the card type, title, description, and image used in a shared link preview.
Meaning
It gives teams control over how page links look in Twitter/X feeds and messages.
Why It Matters

History And Context
Twitter introduced Cards in 2012 so publishers could attach richer previews to links beyond plain text URLs.
