Google's AdSense referrers to earn dollars

Google has expanded its AdSense service by rewarding participants that refer other small web publishers and bloggers with US $100 each. Google’s AdSense service allows firms with web sites or individuals with blogs (a.k.a. web logs) to run Google-supplied text and banner ads and share per-click revenue with the company. Its new referral component works by rewarding referrers with $100 per AdSense sign-up then, but only after new participants have earned their first $100 in ad revenue. To join the new referral program, web site owners must simply add a ‘referral button’ to their sites via their existing AdSense accounts.
