facebook attaching link preview problem

it’s suppose to pick up random text/images, instead mine picks up random code. google analytics to be more exact. any suggestions?

-->

var _gaq = _gaq || [];
_gaq.push(['_setAccount', 'UA-1111111-2']);
_gaq.push(['_trackPageview']);

(function() {
var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true;
ga.src = ('https:' == document.location.protocol ? 'https://ssl' : 'https://www') + '.google-analytics.com/ga.js';
var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(ga, s);
})();

//');
