Google Adsense Verification Code

I have just created new account with Google Adsense and I need to add the AdSense verification code to my site. (according to Google in the head tag)

Where is the best place to place the code for both Desktop and Mobile pages and posts

Google indicates that the code should appear on all site pages and posts.

Thanks

Thanks for the prompt reply. And what about other AdNetworks such as Media.net and maybe others?

For example for one of the ad unit.

They always provide 2 code Head & Body

Head:
Note: Place this code in head tag across website. It’ll remain same for all media.net ad units under this account.

<script type=”text/javascript”>
window._mNHandle = window._mNHandle || {};
window._mNHandle.queue = window._mNHandle.queue || [];
medianet_versionId = “3121199”;
</script>
<script src=”https://contextual.media.net/dmedianet.js?cid=8CUUGK7QW&#8221; async=”async”></script>

Body:
Note: Place this code where ads should appear. Ensure it is across pages with content and regular traffic.

<div id=”997013110″>
<script type=”text/javascript”>
try {
window._mNHandle.queue.push(function (){
window._mNDetails.loadTag(“997013110”, “300×250”, “997013110”);
});
}
catch (error) {}
</script>
</div>

2 questions though:

1. Since it is not Google Adsense code – Do I need to wrap it (as mentioned in your guide) with your tags

Using this code:
<div class=”td-all-devices”>
<!– Your NON AdSense code here – this ad will show on all devices –>
</div>

2. What about the body code: you didn’t answer on where to place it?
3. Does body code should be wrapped with your tags
4. Last question: where is it better to place the code (for both desktop and mobile) via the template (composer) or via the Theme Panel?
