The Google ads that appear on your content pages can be either cost-per-click (CPC) ads or cost-per-thousand impressions (CPM) ads, while AdSense for search results pages only display CPC ads. This means that advertisers pay you when users click on the ads or when the advertiser's ads are displayed on your site. The amount you receive is a portion of the payment for one or both of these actions that occur on your site. Although we do not disclose detailed revenue-sharing information, our goal is to ensure that publishers earn at least as much as they would by joining other ad networks.
