Search firm LookSmart’s five vertical search engines that launched last week will allow more tailored searches based on consumer demographics, along with new ad units for marketers. The company’s new search sites are: teenja.com, a “homework helper” site for teens; gradewinner.com for tweens; 24hourscholar.com for college students; parentsurf.com for all family matters; and gobelle.com, designed for moms on the go. LookSmart said these search engines will let consumers obtain more targeted results than other engines, saving them time and effort as they seek content relevant to their needs.
