One of the largest wants/needs of Google AdSense publishers is to be able to make their AdSense ads work with responsive design web sites.
Although Google won't do it for you automatically, Google is allowing you now to modify your AdSense code to support responsive design web sites.
Google announced they have updated their modification of the AdSense ad code policy to make exception for responsive design and other things. Google is now allowing publishers to modify the code only if it does "not artificially inflate ad performance or harm advertisers."
This is specifically useful in these situations says Google:
- Responsive design: Enabling publishers to create a single webpage that will adapt to the device on which it’s being viewed, whether it’s a laptop, smartphone or tablet, to maximize user experience.
- A/B testing: Running a test by creating multiple versions of a page, comparing user behavior to see which page is the most effective.
- Setting custom channels dynamically: Tracking performance of segments of users, sections of your site, or other behavior to maximize ad and user experience.
- Ad tag minification: Enabling your site pages to load faster by reducing the amount of data to be transferred.
Publishers are extremely happy about this update and are excited to take advantage of this.
