Overview
Ensures that ad tag library scripts are being requested securely. This not only
provides better security for your users, it also improves performance. Since ad
requests issued by GPT always use HTTPS, loading the library itself from the
recommended host via HTTPS ensures that the
browser only needs to open 1 connection for all requests related to ad serving.
Recommendations
Always load your ad tag scripts from an HTTPS URL.
Incorrect
<script>
var el = document.createElement('script');
// Incorrect: potentially loading the ad tag over HTTP.
var useSSL = 'https:' == document.location.protocol;
el.src = (useSSL ? 'https:' : 'http:') + '//securepubads.g.doubleclick.net/tag/js/gpt.js';
var node = document.getElementsByTagName('script')[0];
node.parentNode.insertBefore(el, node);
