Open Graph 預覽工具會向您顯示在發布之前共享連結的外觀。您輸入 og:title、og:description、og:image、og:url 和 Twitter 卡欄位 - 或貼上您已有的元標籤區塊 - 並且該工具會呈現 Facebook、X/Twitter、LinkedIn、Slack 和Discord 並排。您無需即時推送頁面、分享頁面並發現標題被切成兩半或圖像永遠不會加載,而是可以在仍然可以修復問題的同時看到問題。
Open Graph 協定是幾乎每個平台用來建立這些卡片的共享詞彙。刮刀訪問您的頁面,讀取<head> 中的 og: 元標籤,並從中組裝預覽。問題是每個平台都會以不同的方式呈現這些相同的標籤:X 截斷大約110 個字元的描述,而Facebook 顯示接近155 個字符,LinkedIn 將描述完全隱藏在某些表面上,而Slack 將所有內容折疊成一個緊湊的附件。一張卡片中看起來不錯的欄位可能會在另一張卡片中損壞,這就是為什麼同時預覽所有卡片是唯一可靠的檢查。
該工具完全在您的瀏覽器中運行,並且不會對您的網站進行網路呼叫。它不會獲取您的 URL 或抓取您的頁面 - 它可以從您提供的標籤中運行,無論是輸入到表單中還是粘貼到原始 HTML 中並在本地解析。這意味著您可以驗證登入後面、暫存網域上或根本沒有部署的頁面的元數據,並且您輸入的任何內容都不會上傳。
填寫 OG:Title、OG:Description、OG:Image、OG:URL 和 Twitter 卡欄位。 如果頁面已經有元標記,請將原始 HTML 貼到 Parse 框中,然後該工具會將每個已識別的標籤載入到您的表單中。
每個欄位都針對真實平台限制獲得通過、警告或失敗狀態:標題長度、X 和 Facebook 的描述長度、圖像 URL 是否為絕對值和 HTTPS,以及您的句柄是否有效。
查看 Facebook、X 大圖、X 摘要、LinkedIn、Slack 和 Discord 卡。 修剪您的標題或描述,直到每張卡片都清楚地閱讀,並以正確的縱橫比確認圖像載入。
複製完成的 <meta> 標籤區塊並將其貼到您的頁面頭中,或將值輸入您的框架元資料 API。 然後重新刪除每個平台偵錯器中的 URL 以清除任何快取的預覽。
從同一組標籤中渲染近似 Facebook、X(兩種卡片樣式)、LinkedIn、Slack 和 Discord 卡,這樣您就可以發現平台斷裂
放入頁面頭或鬆散的元 HTML 區塊,內建解析器載入每個 OG: 和 Twitter:標記它直接識別到表單中
針對目前平台限制,每個欄位都通過、警告和失敗狀態,包括 X 和 Facebook 使用的不同描述限制
標記相對路徑、非 HTTPS 圖像和缺少的圖像,並提醒您每張大圖卡都假設的 1200x630 (1.91:1) 建議
Generate SEO, Open Graph, and Twitter Card meta tags for any page, with live preview and length checks
Build valid schema.org JSON-LD for Organization, Article, Product, FAQ, LocalBusiness, Breadcrumb, and more - copy the ready-to-paste script tag. 100% client-side.
Check one name across hundreds of TLDs at once. RDAP first, WHOIS fallback, and a verdict of available, taken or unknown — never a guess
Break any URL into its parts - scheme, host, port, path, query, and fragment - and read the query string as a clean, decoded key-value table.
