Sunnyvale, Calif. - In the midst of its efforts to ward off -- or sweeten -- a takeover bid from Microsoft (NASD: MSFT), Yahoo (NASD: YHOO) announced on Wednesday that it will embark on a limited test of Google's (NASD: GOOG) AdSense for Search service, which will deliver Google's ads alongside Yahoo's own search results.

The two-week test will only include Yahoo's U.S. search traffic, will not affect its partners, and will be limited to no more than 3% of Yahoo search queries.

"As previously announced, Yahoo's board of directors is exploring strategic alternatives to maximize stockholder value, including exploration of potential commercial business arrangements," Yahoo said in a statement.

"The company noted that the testing does not necessarily mean that Yahoo will join the AdSense for Search program or that any further commercial relationship with Google will result."
