Search Marketing Startup WordStream Gets $6 Million

WordStream, one of a series of startups pitching easy-to-use search marketing tools, has raised $6 million in a second round of funding. WordStream’s subscription products help customers determine what keywords they should buy for their search campaigns and also what keywords they should play up on their sites. The company says it plans to eventually introduce additional tools as well. WordStream — which says it has more than 500 customers — had previously raised $4 million in a first round of funding a year-and-a-half ago. The new cash comes from new investor Egan-Managed Capital and existing backer Sigma Partners.
