You may already be using AdSense referrals to direct your users to Google products like Google Pack or Google AdWords. Now, you can expand the earning potential of your website even further by directing users to products and services from our base of AdWords advertisers. In just a few minutes you can hand-pick and display ads that will appeal directly to your users’ tastes and interests. After choosing relevant ads or keywords, you will be able to customize referrals units that complement the look and feel of your site. Then you can start directing visitors to the products or services you’ve selected.
With referrals, you’ll be paid when your visitors click through to an advertiser’s site and complete an action defined by your advertisers, such as a sale or sign up. Because these actions are often more involved than a simple click or impression, advertisers pay more for these referrals, which can translate into higher earnings for your site. Further, you’ll see the expected earnings and advertiser performance ahead of time, so you can make the best decisions about what to refer. You can also choose to target the keywords that will ensure you get the highest-paying referrals for your ad space.
