Recently, Google made a change in their ad code by replacing
<script async src="https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js</script>with
<script async src="https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js?client=ca-pub-1234567890123456" crossorigin="anonymous"</script>Reference: Google Adsense Announcement
The old Adsense code looked like this:
<script async src="https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js?client=ca-pub-XXXXXXXXXXXXXXXX"
crossorigin="anonymous"></script>
<ins class="adsbygoogle"
style="display:inline-block;width:350px;height:90px"
data-ad-client="ca-pub-XXXXXXXXXXXXXXXX"
data-ad-slot="XXXXXXXXXX"></ins>
<script>
(adsbygoogle = window.adsbygoogle || []).push({});
</script>
The new Adsense code now looks like this:
<script async src="https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js?client=ca-pub-XXXXXXXXXXXXXXXX"
crossorigin="anonymous"></script>
<ins class="adsbygoogle"
style="display:inline-block;width:350px;height:90px"
data-ad-client="ca-pub-XXXXXXXXXXXXXXXX"
data-ad-slot="XXXXXXXXXX"></ins>
<script>
(adsbygoogle = window.adsbygoogle || []).push({});
</script>
The old JavaScript code used to load the Ad after the page load was:
<script type="text/javascript">
function downloadJSAtOnload() {
var element = document.createElement("script");
element.src = "https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js";
document.body.appendChild(element);
}
if (window.addEventListener)
window.addEventListener("load", downloadJSAtOnload, false);
else if (window.attachEvent)
window.attachEvent("onload", downloadJSAtOnload);
else window.onload = downloadJSAtOnload;
</script>
