Alternate Ads

In AdSense for Content, advertising does not always appear. It can be like this because the advertising inventory related to the content page is already run out or Google can not predict what content of the site actually. If this happens, by default, Google display a public service ads or often known as the PSA (Public Service Ads). Because this type is categorized as donations, so if  it is being clicked, this ad does not produce anything for the publisher. To fix this, Google allows us to install the Alternate Ads.
