Open Graph Image
The image social platforms use when a page is shared.
Definition
An Open Graph image is declared with the og:image metadata property and tells social platforms which image to show in link previews.
Meaning
It controls the visual preview of a page on many social feeds, messaging apps, and sharing surfaces.
Why It Matters
A missing or weak OG image can make a strong page look unfinished when shared. Good previews improve recognition, trust, and click quality.
History And Context
Facebook introduced the Open Graph protocol in 2010, and its metadata conventions became widely used across social and content platforms.
