Before this, we have Adsense’s Referral Program. Now, as an adsense publisher we have even more:
1. Firefox referrals are now available internationally!
You can earn up to USD1.00 when someone download and install google toolbar from your Firefox referral link.
2. Onsite Advertiser Sign-Up
It works like adbrite.com or adengage.com where advertiser can buy a ad space directly from you webpage using thier own Adwords account. To customize your own Onsite Advertiser Sign-up:
- Log in to your AdSense account.
- Under the My Account tab, visit the Account Settings page.
- Scroll down to the Onsite Advertiser Sign-up section and click ‘edit.’
- Upload a logo for your site.
- Use the default description, or create your own to highlight key information you’d like advertisers to know about your sites.
- Choose the color scheme for your landing page.
- Click Save changes.
