If you use WordPress you can use conditional statements as well to pull different information on single posts, category or pages etc.
By using the code below you can control the information you want:
<meta property="fb:app_id" content="YOURAPPID" />
<meta property="og:type" content="article" />
<meta property="og:title" content="YOURTITLE" />
<meta property="og:url" content="YOURURL"/>
<meta property="og:description" content="YOURDESCRIPTION" />
<meta property="og:image" content="DEFAULTIMAGE" />
More details on facebook og meta tags can be found on in the facebook developers section.
