Structured Data & Semantic Web

오픈그래프

Facebook introduced Open Graph in 2010, and many platforms, including KakaoTalk and Slack, now use its metadata for shared-link previews. Support on other platforms, including X, can involve additional platform-specific tags. A 1,200 by 630 pixel og:image is a common preview target, although cropping varies. Open Graph is not a direct search-ranking signal, but it shapes the first impression of a shared link and can affect social click-through.

Business applications and impact#

Improves shared-link presentation and supports social referral traffic.

Implementation guidance and considerations#

Provide accurate og:title, og:description, og:image and og:url values, using suitable preview image dimensions.

Code example#
