HTML會讓我困惑

Question

當我在Facebook上的聊天中複製粘貼我網站的網址時，我得到一個預覽：Boostrap的網格模板。

但是不......我的網站使用Boostrap，但其內容是關於足球！

這裏是我的頭：

<meta charset=utf-8> 
<meta http-equiv=X-UA-Compatible content="IE=edge"> 
<meta name=viewport content="width=device-width, initial-scale=1"> 
<meta name=description content="Scout the opponent team!"> 
<meta name=author content="G. Samaras"> 
<link rel=icon href=img/favicon.ico> 
<title>Cage Scouter</title>

<meta property="og:site_name" content="Cage Scouter"/> 
<meta property="og:title" content="Cage Scouter"/> 
<meta property="og:description" content="Scout the opponent team!"/> 
<meta property="og:image" content="img/favicon.ico"> 
<meta property="og:url" content="http://cgi.di.uoa.gr/~std10093/test/scouter/index.php"> 
<meta property="og:type" content="site"/> // not even sure is site is valid. Blog also didn't change anything 

任何想法？

請注意我如何使用meta兩次。最初，我只有他們的第一套，但得到了相同的結果！

開發人員應該在Facebook OG Debugger處尋找新的更改。
