Without doubt, Google Adsense is one of the best AD network rendering contextual and CPC ads.
Most Adsense publishers aren’t aware of the number of Ads unit per page. In some cases, they are aware, but they do abuse it.
One of the popular Adsense placement abuse i see new blogger doing is adding the double ad format of Adsense for mobile in the top or header of their website.
The Adsense policy clearly state that, double ad format of the Adsense for mobile can only be use in a webpage footer or bottom while that of the single can be use anywhere.
Also you can’t use more than one adsense for mobile unit(either single or double ad format) in a webpage.

Note: in Adsense for mobile, the double Ad format should only be use at the bottom or footer of a page only, while that of the single unit can be use anywhere.
NOTE: You can use 3 Adsense for content and 3 link unit together in a page, but it shouldn’t exceed three(3) each.
