About

One of the largest digital advertising platforms globally, offering a full-stack DSP/SSP with significant owned-and-operated media reach and first-party data assets

Yahoo is a digital media and advertising technology company that operates a demand-side platform (DSP) and connects advertisers with AI-powered tools spanning audience targeting, campaign activation, creative, and measurement workflows. Yahoo Search reaches over 117 million unique searchers per month, and to serve advertiser demand, Yahoo offers a range of ad formats including search, display, sponsored, and mail ads, with search ads designed to reach high-intent audiences. Carousel ads can drive two to three times higher click-through rates than single-image ads, native video ads have been shown to drive a 50% increase in brand favorability and a 28% increase in purchase intent, and Yahoo Mail ads have produced click-through rates as high as four times industry averages. Yahoo DSP's recently launched Agent Network integrates 23 ad tech partners — including DoubleVerify, Integral Ad Science, LiveRamp, and Snowflake — across audience and contextual targeting, campaign activation, creative, and measurement, extending Yahoo's broader AI strategy that allows advertisers to use Yahoo's native AI agents, bring their own, or combine both through open APIs. Rather than locking buyers into proprietary tools, Yahoo is betting on interoperability, opening its platform to partner-built agents through standardized integrations designed to work alongside agency-built systems and other external technologies. Beyond advertising, Yahoo aggregates news from content providers and newswire companies, with company profile and industry listing data supplied by Capital IQ and Morningstar.
