This is the documentation of the Responsive Ads plugin for Advanced Ads.
Set up the fallback width
In some cases, the plugin might not be able to retrieve the browser width and falls back to an assumed width of 768 px. You can change that fallback width in Advanced Ads > Settings > General > Responsive Ads.
Display ads only for specific browser widths
Once you installed and activated the plugin, you can set the browser width a visitor must have to see the ad. Go to the Visitor Conditions meta box on the ad edit screen and create a new visitor condition with the browser width type.
Once you added the condition you can choose whether the browser of the user must have a specific width or a width higher or lower than that to see the ad.
You can also combine multiple browser width conditions to set a range. The following example is a setup to display an ad only on browsers with a width between 480 and 767 pixels.
Display ads for tablets
While the default mobile visitor condition includes smartphone and tablet devices, the Responsive add-on has a dedicated condition for tablets only.
You can find it among the visitor conditions and select whether to show or hide the ad on such devices.
In order to target smartphones only, you should use the following setup:
If you have troubles finding the correct ad size, you can activate the frontend assistant. This will allow you to see the size of your ad, ad container and window in the frontend.

To activate the assistant go to Advanced Ads > Settings > General > Activate size assistant. Only logged in users (admins) will see the helper.
AdSense Responsive Ads
The Responsive add-on comes with a dedicated support to set up specific sizes for AdSense responsive ads. Setting up specific sizes instead of using the auto sizing feature that is coming with AdSense responsive ad units can boost your income even more. You can define the default size of the ad as well as sizes for custom browser widths without the need to code.
This feature is explained in more detail in the tutorial How to set up AdSense Responsive ads with custom sizes in WordPress.
List of responsive ads
You can use the list of responsive ads to see if your responsive ads are set up correctly. You can access the following view under Advanced Ads > Advanced Ads > List of responsive ads by browser width (page bottom).
The dark places in the visualization are the sizes where the ad is visible. E.g. the Medium Rectangle ad that belongs to the Sidebar group is visible in browsers with a width ranging from 0 to 1000 pixels.
