I paste this code and save.
<script>
(function(i,s,o,g,r,a,m){i[‘GoogleAnalyticsObject’]=r;i[r]=i[r]||function(){
(i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),
m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m)
})(window,document,’script’,’https://www.google-analytics.com/analytics.js’,’ga’);
ga(‘create’, ‘YOUR_UID_REPLACE_THIS’, ‘auto’);
ga(‘require’, ‘displayfeatures’);
ga(‘set’, ‘campaignSource’, ‘Facebook’);
ga(‘set’, ‘campaignMedium’, ‘Social Instant Article’);
ga(‘set’, ‘title’, ia_document.title);
ga(‘send’, ‘pageview’);
</script>
After it got saved it looks like below:
<iframe><script>
(function(i,s,o,g,r,a,m){i[\’GoogleAnalyticsObject\’]=r;i[r]=i[r]||function(){
(i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),
m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m)
})(window,document,\’script\’,\’https://www.google-analytics.com/analytics.js\’,\’ga\’);
ga(\’create\’, \’UA-Xxxx\’, \’auto\’);
ga(\’require\’, \’displayfeatures\’);
ga(\’set\’, \’campaignSource\’, \’Facebook\’);
ga(\’set\’, \’campaignMedium\’, \’Social Instant Article\’);
ga(\’set\’, \’title\’, \’FBIA: \’+ia_document.title);
