Referrals 2.0 launches to all AdSense publishers
This past March, we launched a referrals beta to test the feature and iron out some wrinkles. Now that we've finished our testing, we're pleased to announce that referrals 2.0 will soon be available to all AdSense publishers in referrals-supported languages.
Context & Ripple Effects
Referrals are not new to AdSense — Google first shipped a referral feature back in November 2005, letting publishers earn by driving sign-ups rather than clicks. The March 2007 beta was the test run for a rebuilt version of that product, and this announcement closes the loop: testing is done and Referrals 2.0 goes to every AdSense publisher in referrals-supported languages.
The significance is pricing, not novelty. A general rollout moves cost-per-action advertising out of a limited test and into the default toolkit alongside AdSense's click-based ads, giving advertisers a second way to buy and publishers a second way to earn on the same inventory.
First-order effects
- Every AdSense publisher in supported languages can now run referral units, earning when site visitors complete an advertiser's specified action instead of merely clicking.
- Advertisers gain a performance-priced channel inside AdSense, paying only on completed actions rather than per impression or click.
Second-order effects
- Publishers now arbitrate between CPC and CPA units on the same pages, pushing them to favor placements and content that convert rather than merely attract clicks.
- Click-based advertisers face new competition for AdSense inventory from conversion-paying advertisers, pressuring bid dynamics on the network.
Third-order effects
- If the pattern holds, AdSense evolves from a single-pricing click market into a mixed CPC/CPA marketplace, with Google as the measurement layer deciding which actions count — a structural shift in how web publishing is monetized.
The trend: Ad networks are broadening beyond click-based pricing toward action-based monetization, making the publisher's page a venue for measured outcomes rather than raw traffic.
