Today I have been facing problem sharing my website link at facebook. It was showing the wrong description, which I have recognized as the previous description of my site. After changing the description google is showing okay, but facebook seems to fail at getting the new description. After some googling I have come to that post at stackoverflow (a great source of help for developers).
So you have to follow the following steps to refresh your page description at facebook –
- Go to the facebook debugger link at http://developers.facebook.com/tools/debug
- Put your site address in the input box
- Press debug
Viola! Your site description has been updated on facebook too.
