I have created my website using wordpress 3.4.1 and, I tried sharing my webpage in facebook. I do not get any thumbnail or the basic blog description in the facebook post. Instead I get “No Title”. I know this question has been asked a number of times in wordpress forums. But, most of them are leading to dead ends. Can some one help me in this regard.
PS: I tried using the facebook debugger (http://developers.facebook.com/tools/debug) I get the following
Error Parsing URL: Error parsing input URL, no data was scraped.
You need to add OpenGraph tags to your page, or even easier, finf a WordPress plugin to do it for you. Run the page through the debugger again and the issues should be fixed.
Just like what Niraj said you need to make sure you have the open graph meta tags on your blog. Here is a plugin which will add them http://wordpress.org/extend/plugins/facebook-open-graph-meta/.
