Does someone knows how to use Google Social Interaction Analytics with the Tumblr share button? (which is hosted on my Wordpress blog)
I've done it for Facebook and Twitter (i.e: http://visualise.ca/anne-au-cherry)
There is no information about in google's docs : http://code.google.com/apis/analytics/docs/tracking/gaTrackingSocial.html
P.S.: What about the Pinterest button? ;-)
The Tumblr Share button doesn't have any callbacks for completing the share. However, its just a link to another page. So, you can trivially add click-tracking to it:
$(".tumblr a").click(function(){
_gaq.push(["_trackSocial", "Tumblr", "Click"]);
});
The Pinterest Pin It button is in an iframe, has no JS API, no click tracking, no "on pin" callback. So, you're lost there in terms of tracking.
