How in insert Adsense Auto ads on my Blogspot Blog

I know how to set up auto Adsense on my Wordpress blog. How do I do it on my Blogspot Blogger blog?

First things first...

Make sure that your Blogger domain (e.g., mysite.blogspot.com) is listed as a verified site in your AdSense account.
Use a theme that will look good across different devices, e.g., Contempo, Notable, Soho, or Emporio.
If you are using a theme that requires you to select a mobile version, make sure you select the "No. Show desktop theme on mobile devices" option, and use a responsive theme that will look good across different devices. (A good example is Dynamic Views.)

Note: If you change your theme in Blogger, make sure you add the Auto ad code to your blog again.

How to add the Auto ad code to your blog...

Sign in to Blogger.
In the top left, click the Down arrow .
Click the blog you want to show Auto ads on.
On the left menu, click Theme.
Click More Edit HTML.
In your HTML, copy and paste the Auto ad code between the <head> and </head> tags.
Click Save theme.
