I have recently started a Blog, The blog is made using Blogger, Then I thought of preparing my site to show ads and then I created a Adsense account and then in the sites section I had given the URL of My Blog and after some days I saw the sites section and there was written that needs attension, Then I clicked on it and I found that there was wriiten a Notice and a code which I have pasted below :-
Copy and paste this code in the HTML of your site, between the and tags.
Your AdSense code
<script data-ad-client="ca-pub-4836518523777258" async src="https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script>
Now I am Confused That where I have to add this code, In my blog theme's HTML which I have installed currently or some where else can someone tell me.
