There is an awesome plugin out there http://wordpress.org/extend/plugins/fix-facebook-like/ which fixes errors that can crop up with incomplete Facebook Meta Data. Basically when Facebook goes to submit a Like they attach a lot of information to it such as a description, link, type, so on. This data is what ends up in Facebook Insights (among other places I am sure) and is generally used to categorize the information. What Fix Facebook Like does is rebuild that data, which can be outputted wrong from WordPress.
There is a small issue with the plugin though, it comes down to the Type field used by Facebook, “og:type.” If this “og:type” is wrong Facebook considers it a showstopper and the Like system breaks. The plugin fills this out automatically and every now and then hits an “og:type” Facebook doesn’t recognize and everything grinds to a halt. The easiest fix is to go into the PHP for the Fix Facebook Like and remove the line:
< meta property="og:type" content="" />
Removing the line means Facebook will try and figure out the type on it’s own. Alternatively you can look up the “og:type” and fill it out manually, there is a site here http://ogp.me/#types that will do just that for you. The modified plugin means all your Likes will go through and have the proper meta information with them!
