LookSmart Overview

It's hard to find anything online without looking unless you're talking about ads. LookSmart helps publishers, advertisers, and consumers see what they want when it comes to online advertising. The company earns most of its revenue through its Advertiser Networks offering (AdCenter), which provides advertisers with targeted, pay-per-click search advertising, contextual advertising, and banner products. It also offers Publisher Solutions that help content publishers maintain advertiser relationships online. LookSmart completed its transition to a full-on provider of advertising and publishing services after a couple of years spent divesting its non-core consumer website assets.
