After Microsoft's last week announcement about its ad platform's "exclusive targeting features" which allowed registered users to select "whom, what time of day and to what geographic location" their ad would be shown, Yahoo! has announced that it will be rolling out a "completely redesigned" search advertising platform in the third quarter of this year.

This new platform would enable marketers to more quickly launch search advertising campaigns across the search giant and its distribution network, "and help better overall return on their search advertising investment."
