Responsive web design is the trend these days as more and more people are browsing the internet through their smartphones and tablets. If your Blogger blog is responsive, you can consider adding responsive ad units to the blog to maximize your Adsense earnings.
Adsense responsive ad code automatically serves different ad sizes based on the space available and also has support for ad size changes after a screen orientation change (e.g., when a tablet or phone goes from portrait to landscape).
By using a responsive ad unit, you can control the size of the ads on
your page, in line with how you control the layout of the rest of your
page across devices.
If your blog design is responsive, all you need to do is to generate responsive ad code and add it to your blog’s html.
