Adding content.ad popup code to my hueman site

My site is socialmediamorning.com and I would like to add content.ad exit pop to my page. I have the code from them but I can’t find where to place to activate it. Thanks for any help in advance.

<div id=”contentad133109″></div>
<script type=”text/javascript”>
(function(d) {
var params =
{
id: “cf73f1e4-9554-4e11-8773-e0d02e7875a4”,
d: “c29jaWFsbWVkaWFtb3JuaW5nLmNvbQ==”,
wid: “133109”,
exitPop: true,
cb: (new Date()).getTime()
};

var qs=[];
for(var key in params) qs.push(key+’=’+encodeURIComponent(params[key]));
var s = d.createElement(‘script’);s.type=’text/javascript’;s.async=true;
var p = ‘https:’ == document.location.protocol ? ‘https’ : ‘http’;
s.src = p + “://api.content.ad/Scripts/widget2.aspx?” + qs.join(‘&’);
d.getElementById(“contentad133109”).appendChild(s);
})(document);
</script>
