您需要使用Open Graph元标记在Facebook上进行此类共享。WordPress存储库中有很多插件可用于此。

例如：

<meta property="og:url" content="http://sharing/url" />
<meta property="og:type" content="article" />
<meta property="og:title" content="Title of the post" />
<meta property="og:description" content="Description or excerpt of the post" />
<meta property="og:image" content="YOUR FEATURED IMAGE SOURCE" />

你也可以预览你发布的FB爬虫的外观here.
