In addition to Google phasing out AdWords pay-per-action beta, Google AdSense Team blog has announced, retiring the AdSense Referrals program during the last week of August.

Here’re some alternative options to consider:

• Google Affiliate Network: As part of the integration of DoubleClick, the DoubleClick Performics Affiliate Network will now operate as the Google Affiliate Network for advertisers targeting users located in the United States. Similar to the AdSense Referrals program, the Google Affiliate Network enables publishers to apply for advertiser programs and get paid based on advertiser-defined actions instead of clicks or impressions. For further details, please visit: http://www.google.com/ads/affiliatenetwork/.

  Through the network, advertisers can open their ads to all publishers in the network, or select specific publishers that match their criteria. You can set a CPA for your entire campaign or establish custom payment schedules for specific publishers -- such as a higher CPA for a particularly optimal placement. The Google Affiliate Network is currently a separate product from AdWords and AdSense. As with AdSense, publishers must apply and be accepted into the network.[Google AdWords Team Blog]

• AdSense for content ads: If you have less than three AdSense for content ad units on a page, you may wish to replace the referral ad units with standard AdSense for content ad units.

If you currently use referral ads, either to promote Google products or offerings from AdWords advertisers, AdSense Referrals code will no longer display ads beginning the last week of August. It’s advisable to take the following steps before the product is retired:

• Remove the referral code from your site(s): Please take a moment to remove all referral code from your sites before the last week of August, so you can continue to effectively monetize your ad space.
• Run and save all referrals reports on your desktop: Create and save all reports related to the referrals program on your desktop, so you continue to have access to your valuable campaign information.
