AdSense is Google‘s advertising platform for publishers. AdSense allows website owners and publishers to monetize their websites by placing text, banner, video and rich media ads on their pages. AdSense supports PPC and CPM strategies.

While AdSense can be an effective revenue source for publishers, ad placement is a Google ranking factor. Too much AdSense, especially above the fold, makes a page look low quality and can result in lowered search rankings. Egregious abuse can result in harsh algorithmic and manual Google penalties.
