In the fast-moving world of e-commerce, this fully revised second edition includes updates on test metrics, prioritization and personalization, alongside updated case studies and newly recommended tools. E-commerce Website Optimization is an invaluable book for those seeking to implement a data-driven ethos for their organization's e-commerce programme, for everyone from chief digital officers and heads of online sales, to entrepreneurs and small business owners.
