To give you editorial control over the Adsense Google ads that appear on your site, Google offers several options for reviewing and blocking ads that may appear on your pages.
When you create a Adsense Google ad experiment, you can opt to let Google choose the winner for you. Google will automatically apply the winning setting after your experiment has finished. If you prefer not to select this option, then you’ll need to choose the winner of the experiment yourself.
You must be at least 18 years old, or have a legal guardian older than 18 years of age who can handle your payments via AdSense. Create content that meets Google advertiser-friendly content guidelines
