Open Graph
Open Graph is the protocol that controls how your page looks when shared on Twitter/X, LinkedIn, Slack, Discord, Facebook, and messaging apps. The core tags are og:title, og:description, og:image (1200×630 recommended), and og:url. Missing OG tags are the #1 reason launch posts don't get shared — the preview looks broken. A single og-image.png in /public is enough for most launches.
Open Graph은 페이지가 Twitter/X, LinkedIn, Slack, Discord, Facebook, 메신저 앱에 공유될 때 보이는 모습을 제어하는 프로토콜이에요. 핵심: og:title, og:description, og:image (1200×630), og:url. OG 태그 누락이 런치 포스트가 공유 안 되는 1번 이유 — 프리뷰가 깨져 보여요.
Open Graphは、Twitter/X・LinkedIn・Slack・Discord・Facebookやメッセンジャーで共有されたときの見え方を制御するプロトコル。主要タグ: og:title, og:description, og:image（1200×630推奨）、og:url。OGタグの欠如はローンチ投稿がシェアされない最大の理由です。
