function matchResultsCallback(data){
var scriptTag = document.createElement(‘script’);
scriptTag.type = “text/javascript”;
scriptTag.text = scriptTag.text + “/* */\n”;
$(‘body’).append(scriptTag);
$(‘body’).append(“”);
//I have also tried this bit above using the same method as ‘scriptTag’ with no luck, this is just the most recent iteration.
var scriptTag2 = document.createElement(‘noscript’);
var imgTag = document.createElement(‘img’);
imgTag.height = 1;
imgTag.width = 1;
imgTag.border = 0;
imgTag.src = “http://www.googleadservices.com/pagead/conversion/993834405/?label=bSpUCOP9iAIQpevy2QM&guid=ON&script=0”;
$(‘body’).append(scriptTag2);
$(‘noscript’).append(imgTag);
