為何在Facebook分享網址沒有圖片預覽?

Facebook專頁及網站內容管理者都有機會在Facebook的「近況」中鍵入網站網址作分享,一般都能顯示該網頁的主題圖片(如有)、標題及首段 “?*
部分文字,並可加以修改,但偶爾主題圖片會不出現,令人頭痛。其實這是因為網站並未載有Open Graph Protocol-一個讓社交媒體更精準地了解網頁內容的技術,例如該網站是否已被讚好和分享,甚至讓管理員追蹤讚好數據。至於要解決Facebook網址預覽圖問題,需在網站加入數條程式碼(meta property),但如網站採用內容管理系統(如WordPress),則方便得多!只需安裝Open Graph相關的plugin進行簡單設定,再使用Facebook Open Graph Object Debugger (https://developers.facebook.com/tools/debug/)測試或刷新即可。
