In an announcement made just moments ago, Yahoo has formally decided to try a limited test of Google’s AdSense for Search program in their search results. From the release:
The test will apply only to traffic from yahoo.com in the U.S. and will not include Yahoo!’s extended network of affiliate or premium publisher partners. The test is expected to last up to two weeks and will be limited to no more than 3% of Yahoo! search queries.
In response to speculation earlier today, Business Week’s TechBeat pointed out that “Analysts have long pointed out that Yahoo could jack up its profits overnight by outsourcing its search advertising to Google, which generates much more revenue per search than Yahoo. Indeed, such a deal has been rumored for at least the past year.”
