Zen den is a San Francisco-based website design firm and creative agency. Zen den utilizes e-commerce solutions and CMS systems to enhance its commitment to optimal branding and graphic design. Zen den uses open-source CMS to design websites that are tailor-made to the client's needs and the marketing landscape that that client works within. Zen den also uses e-commerce solutions from Magento to integrate an array of e-commerce functions into completed websites. Magento is the best tool for this job since it can be scaled up or down depending on the client's budget, company size and needs. Search engine optimization is one of the marketing tools that Zen den takes advantage of to deliver effective marketing campaigns. In recent years, Zen den has used Google AdWords and email marketing campaigns to give its clients' brands even more exposure online.
