How much will I earn with AdSense?

There's no precise answer, because your earnings will depend on a number of factors.

• The type of ads appearing on your pages: By displaying ads with AdSense for content, you can display ads that are paid when users click them or when users view them. All ads compete in an ad auction, and our system automatically picks the advertisers who are willing to pay the most while ensuring a good user experience.
• The pricing of ads appearing on your pages: Not all ads are priced the same, so factors such as changing advertiser budgets, your specific content, and the ads your users choose to click will cause your earnings to vary even from day to day.
• How many AdSense products you use: You can earn from AdSense in many different ways -- by displaying ads on your webpages, by providing search to your users, and more. Using more AdSense products will increase your potential earnings.
