The FaceBook’s Open Graph (OG) Meta tags have og: as prefix, followed by a specific property element. The data for the specified property is given using the content attribute. So with this meta, you can tell the content type to FB – whether it’s url, site name, image, audio or other types.
The syntax for Open Graph tags is:
<meta property="og:tag name" content="tag value"/>
Look at the below header section to see FaceBook OG tags in action.
<head> <title>Webfroze Home Page FB Demo</title> <meta property="og:title" content="Webfroze Home"/> <meta property="og:type" content="blog"/> <meta property="og:url" content="http://www.webfroze.com/"/> <meta property="og:image" content="http://www.webfroze.com/logo.png"/> <meta property="og:site_name" content="Webfroze"/> <meta property="og:description" content="Blogging, WordPress, CSS and more."/> </head>
You can just paste this meta tags in your WordPress header.php file. It works perfectly. Visit Open Graph protocol – FB Developers page to see the big list of supported Open Graph meta tags. You can use FB Debugger tool to validate the tags.
