Yahoo! Search Marketing (searchmarketing.yahoo.com) is a keyword-based "Pay per click" or "Sponsored search" Internet advertising service provided by Yahoo!.
Yahoo began offering this service after acquiring Overture Services, Inc. (formerly Goto.com) (overture.com). Goto.com was an Idealab spin off and was the first company to successfully provide a pay-for-placement search service following previous attempts that were not well received.[1][2][3]
