How can I tell if having the embedded Facebook iframe/html5 is any good at gathering a meaningful amount of page likes? (High enough to justify the real estate and extra load time it takes.)
I see plenty of big sites dropping it. In fact I just went to ten or so random places and couldn't find any surviving example (not even buzzfeed!), not even of the tiny version of it.
In the insight section, I'm not sure where to look - some of the likes are attributed to 'your page', but does that include your Facebook page and the plugin on your site and, if yes, how many likes from which?
